Thanks for the great feedback. Unfortunately, I can not add those after the video has been released.
Also, I no longer have the test setup. Ready to move on to the next project. I will show that in future test videos of other converters.

Does adding capacitance help any? Adding a capacitor or replacing the caps with a higher uf rating?
Great feedback!
I ran a quick output capacitor calculation, and the numbers came close to the values already used for this converter. But I will test that with my converter design. However, making converter outputs more capacitive helps with better peak-to-peak output ripple.
Thanks again!

Thanks so much for this
I have a project at hand that requires dc dc converter for charging of lithium battery. The challenge at the moment now is that the primary battery pack i have is 48v 50A configuration which i want to use for charging a battery pack of 60v 50A. But the dc dc converter i have which you have been using in the video has input current limits; 10-30v 30A and 31-60v 25A. These limits will not work for my project.
Please how can i increase the input current to suite my project. Should I just reinforce the input current fuses
Your assistance at this point sir will be much appreciated
Wonderful question.
But you are already on the right track. With your 48V power supply as an input to the 1500W version of the converter, you should be able to get a continuous output power of up to 1300W or more out of the converter with good cooling fans.
For a 60V LiFePO4 battery, you should need a charging voltage of about 72V....please double-check your battery specifications and manufacturer recommendations.
Now, 72V at 1300W means that you will have a charging current of 18A that will be delivered to your battery.👍👍
The only bottleneck for you will be that it would be a slower charging process....about 3 hours instead of 1hr. This also means that you will charge your battery at about 0.4C. Honestly, this is better, in my opinion, and your battery will last longer as you will get more cycles out of your battery system.
You can also try making the modifications I showed in this video to see if you could raise your charging current well about 20A....this could get you close to 0.6C charging capacity.
I am also working on other alternatives. Stay tuned.
I hope this helps.

Nice mod ! Did you lower the switching frequency so the current has a longer period and can reach so a higher amperage ( together with the higher inductance) ?
You are pretty much on the right track. However, in a nutshell, every inductor has a switching frequency that optimizes its energy transfer performance. Being able to vary the switching did help tune the converter for better efficiency.
I will make a follow-on video in the future to explain inductor design better.
Stay tuned.

@@theinnovati0nlab782You can improve your efficiency and power delivery by replacing the mosfet and diodes! I build my Owen boost converter with an SB1060L (ultra-low power loss super baria diode) and two AON6276 connected in parallel. The AON6276 has a lower Qg and resistance than the original in your boost converter. With these modifications, my boost converter runs cold under high load and can output more power. I'd like to see how my version performs with your coil design in the next video.

ANOTHER GREAT VIDEO!!!! I have gotten about 16 minutes into it...will finish tonight.
a couple things so far:
1) How many strands of 22AWG wire did you use for the thick windings?
2) ...may be premature: At about timestamp 15:00 for 10kHz to 60kHz, I think I would have used 'at least' 1K for the fixed resistors, since at 10kHz, R=100K already. And @ 60kHz; R=16.7k.
At pot extreams, 200 Ohms gives 5MhZ............2000 Ohms gives 500kHz
THANKS FOR CONTINUING...

Hello, wonderful friend!
Thanks a lot for the great feedback!
All your questions and comments were addressed in chapter 4 of the video.
The 2X 100 ohms was barely used as a stand-off/jumper to 100K trim potentiometer.
But I see your concern about the pot extremes...having the scope to keep a close eye on the PWM waveform while making the switching frequency adjustments.
A couple of things to consider are that the TL494 has a max frequency rating of 300KHz, and it should not be able to exceed that. Also, looking at the formula, the frequency of the is inversely proportional to a product of RT and CT. So, it is not solely dependent on RT.
Let me know if you have more questions when you have been able to watch the entire video.

I was charging my battery pack with this. While charging, I turned off the adapter plug and turned it on while my battery was connected. Then the output side of the regulator exploded and the diodes burned out. I wonder if there was a backward current from my battery? Should I disconnect the battery first before removing the adapter?
Sorry to hear about the failure you encountered. However, It is never advisable to power ON your converters with loads already applied.
What killed your converter is probably an output overload or cureent surge - as the converter was still trying to regulate. These converters have output rectifier diodes that should be reverse biased with respect to your batteries' polarity.
You should never leave your battery connected to these converters, especially when they are powered off because they will discharge your battery over time. Yes, the output diode is supposed to block any incoming power to the converter, but in reverse bias mode, there is still some leakage current that gets through. At reverse bias, the Junction resistance/impedance of that diode is high....but not infinite, thus the it never like an OPEN switch.
I made a video a while ago to detail a 6-step method for using these converters as a constant current/voltage battery charger.
Please, I highly recommend that you watch this video👇👇👇

However, I only know how to implement a similar concept using a different converter topology.

Hello friend, the difficult becomes simple, great knowledge, keep it up.
Please do a video on INDUCTOR calculations , 47 microH to 50 microH, 200Amp, for a 24 VDC to 220VAC solar inverter at 5000 Watts operating at 50Hz with a 25 kilogram toroidal iron core transformer; the EGS002 is the control board, and it produces 22 KHz too.
Is skin effect important here also?
The chinese sellers of such inverter boards say to use 47 to 50 micro Henry (at ~~200 Amps max).
Wonderful, it seems you are talking about an LC filter circuit for pure sine wave inverter.
The big, heavy, and bulky toroidal tranformer is a soft iron torroidal core that should be a transformer and not an inductor. Realistically, it should operate down to about 50 to 60Hz. Skin effect only applies to high frequencies, and you should not be worried about it for the main toroidal transformer.
However, you should definitely consider skin effect for the filter inductor needed for the LC filter circuit. The LC filter is supposed to serve as a low pass filter to block the 22KHz switching frequency that MOSFETs or IGBTs used to chop down the DC power to a stepped waveform.....long but simple story, depending on who is telling the story...hahaha!
The 22KHz is the first stage that is used to create a digital sine wave PWM. But then, given that soft iron cores cannot hand 22KHz, it needs to be filtered off by the LC low-pass filter first.
f(cutoff) = 1/(2pi*SQRT(LC)
You are right. This will have to be a video. Text explanation would take a 200-page thesis...hahaha

isn't the converter need some power diode or something like that?, which I assume is what the heatsink is trying to cool, so... isn't that is the other limitation?
but question aside, it's a really great video man, love it
Thanks a lot for the thoughtful feedback.
Your question was on point. Yes, there are output rectifier diodes on the unit, of course. They should be able to handle greater than 40A at the output. This is why I am using 3X fast recovery diodes in my design... Maybe an overkill, but I prefer to derate components to minimize unnecessary dissipation and stress on the components.

Thanks so so much for the video sir, God bless. Please sir it will be nice if you could help us with the reason they used 35UH inductor and the theories behind it sir thanks and stay bless.
Wonderful question👍👍👍
I was avoiding getting too deep on the inductor design for this video....because I didn't want to make this a 2-hour video, hahaha.
However, that number came from a calculation of the CRITICAL INDUCTANCE for the boost converter - operating under continuous conduction mode. However, with that said, inductor construction itself presents a major difficulty in reaching the desired inductance because it is usually very difficult to pack the windings, though toroidal core due to the small inner diameter.
I would have preferred a higher inductance value. However, 35uH was what I could feasibly achieve with my build.
Please research the following as you may find them helpful;
💥core materials
💥boost converter critical inductance.
💥Continuous conduction mode
💥inductor saturation currents
💥Skin Depth/effect.
I will make a future video to explain this better.

The more power you drive over a DC/DC converter the easier is it to reach higher efficiencies. For synchronous buck converters you can reach quite easily 5 kW of transferred power with a loss of less than 50 W because you don't have Schottky diodes in your system, which typically have a voltage drop of at least 0.5 V in conduction. So if you have a current of 200 A at 25 V you will get 100 W of power dissipation in the Schottky diodes allone. If you use a cascade of 4 power MOSFETs with only 0.5 mOhm in a half bridge you will get only 20 W of power dissipation in the power MOSFETs.
The challenge of power MOSFETs in half bridges, however, is "phantom" opening of the low side switches due to steep voltage rises coming from the high side. The capacities between drain and gate and gate and source are acting like a capacitive voltage divider. The inner resistance of the internal bond wire to the gate even if it is very small like just 2 or 3 Ohm will let the gate float up for a while that it can exceed the gate threshold voltage, leading to a "silent" opening of the low side MOSFETs. So the current shoots though and not through your inductor, which stays uncharged. So when you increase the input voltage a sudden collaps of the output voltage happens leading a extremely high shoot through currents.
Thanks a lot for the great and super constructive feedback!!👍👍
Great points, and I couldn't agree more.

Are these even ferrite? They look like Sendust cores to my eye.. It's more like iron powder core..you know the yellow/white or green/blue rings in many appliances, but without many of the losses and hysteresis, etc. issues of the iron powder ones.. also i think ferrite would have needed an airgap to store the energy between the switch cycles which is kinda inbread property of iron powder or sendust -type of cores.. 😊 By the way..very good video! I couldn't spot half truths or other issues there at least with single watch..and the converter efficiency is right there where it should be!!

You can also search the part number shown in the video to dive in a bit better into the specs. As for the color coding of cores....I found that this is really an unregulated standard, and most manufacturers can just paint any color on anything these days.
I hope this makes sense to you.

www.theinnovati0nlab.com
@@theinnovati0nlab782Hi!😊 Yep...the colors are a mess.. I think only properly color-coded rings are manufactured by Micrometals, and they are iron-powdered rings. Chinese manufacturers sometimes clone them, but no-one knows if they are even close to originals. I think i've never seen any coding with ferrites. I'm electronics repair engineer thus have access to different magnetics from variety of deceased products..so i've tried in the past to define what stuff is usually what, but it's very hard.. It's easy to define whether it's high permeability or low permeability material (or ferrite vs iron powder), but all other parameters from them is just impossible or too impractical with regular tools found in basic workshop.. I've had a hobby of hf dx radio listening and best stuff to salvage are the high permeability ferrites in smps common mode chokes.. They make excellent impedance transformers for receive antennas, etc.. (not for transmitters though!) Lazy man's hf (lw, mw, sw bands) isolation transformer is made out of such ferrite and 10-15 turns of a single twisted pair dismantled from cat cable.. other wire's a primary and the other is a secondary..that's some literal transmission-line transformer..😅
I built about 700-800w boost converter from scratch for some solar project and i did quite a bit of research and few prototypes and ended up getting sendust (i think that's Magnetic's Inc. name for FeSiAl cores..i think Micrometals use name CoolMu).. They looked identical up to the point of print font on this video..that's why they looked familiar..As You suggested i dropped the numbers from Your cores into my AliExpress app and apparently these ARE sendust cores.. (Tangda sendust FeSiAl toroidal cores inductor OD*ID*HT 48*23*19 mm AL: 281nH/N2 Ue: 125 AS184125A CS467125 77438-A7 .
a.aliexpress.com/_ExU3our )
My switching freq was 62kHz and airgapped core from Samsung 24v microwave oven saturated immediately (i have no specs about the mwo inverter switching frequency..and it utilized a flyback topology so i didn't have high expectations but tried anyway to see how it would survive in boost converter..)..i didn't want to start experimenting with air gaps and stuff so i went straight to powdered iron.. Yellow-white micrometals core worked without saturation but i felt i could choose a core with less losses so i went with sendust..very good stuff!
I think You would have had problems with core saturation if they had been ferrite since your toroids have no gap..
Since boost converter needs to store all the energy into the core during the on state of the switch which is released into the load during the off state of the switch it's way more fiddlier to do it with ferrite cores..😅..at least for me..
Schematics?
It was all in the video.

My problem is that I need a buck converter capable of delivering at least 30A at 3.6V, 60A or 90A would be better😅 but there arent many ready made converters that dont blow a giant hole in my bank account😂
I hear you!
There are some Analog Devices buck converter modules that can give you what you those specs. However, as you rightly said, they are never cheap.
You can always check on Mouser electronics to see if they have something that you can afford.
A custom design is another alternative, but they are expensive as well - unless you can build it yourself - but then it also takes time.

Kendi indiktörlerini paralel bağlamak daha akıllıca olurdu.Bu devrenin akım ayarlama sorunu var bu yüzden sadece voltaj yükseltmesine izin verip akım ayarını başkaca bir devre tasarımıyla yapmayı düşünmeli.Ve bu devrenin yaptığı işi çok daha az elemanla ve çok yüksek frekanla yapmak pekala mümkün.Örneğin radyo frekansında fm çıkış devtreleri tam olarak buna benzer transistör maksimum voltajı olan 33 voltu 220 volta 100 megahertz de çevirmek.Size bir sır vereyim hava endüktanslı yğksek frekanslıçok verimli ve çok küçük devreler mümkün.Yakın grlecekte olacak olan bu.
Great feedback.👍👍👍
I see your point about going to higher frequencies....I already know this, so it is not a secret that needs to be unveiled to me.
Now, what you may not know is that for high power designs, you want to be very careful with switching frequencies that approach the MHz range because at such frequencies, every single component you have on the power board - even the copper traces, begins to act as high frequency antennas. This is fundermentally as a result of parasitic inductance and capatances of components on the board.....things that you would never have worries about if you stayed below 100KHz.
Also, at such high frequencies, you may be venturing into the land of fcc violations for a commercial power supply. This means that you have to add a lot more to the design to ensure an effective Faraday cage or EMI shield around your design. You don't want to build a converter that could disrupt other high-frequency devices around it.⚠️⚠️⚠️
You see, there is a lot that comes between the land of theory and what goes on in an actual test lab.
You have to make the rubber meet the road with your designs. Design feasibility, cost, safety, regulations, power density, material availability,....I can go on.
Also, higher frequency designs take longer and require more analysis and detail......high frequency designs are never cheap, my friend.
Higher frequencies are used for very expensive converters where high POWER DENSITY is super desirable. But not everyone can afford such converters! You should never compare those to these super DUPER cheap $25 converters - not fair at all.😊
Also, this technology already exists, but it is very expensive....so it's not science fiction.
I hope this helps.

By using 3.2v LFP cell can we run e-bike of 48v 1000watt
Please elaborate. I am not sure I understand your comment.

No you can't, and because two things.
1) This converter only step up voltage from min 8.5V and your battery is 3.2V
2) One cell battery in practice have low power so it can't deliver 1000W
@@markhivin8670
By using 3 or 4 cells is it possible
@@aabb-xt8kl Yes, but it is in your interest to have higher voltage because efficiency is higher with higher voltage so you will waste less energy of you battery to power your bike.
@markhivin8670
I couldn't agree more.
Low voltage, high power, bad combination.
Also, these converters have an input/output current limit
....so that by itself limits you anyway.

กระแสไฟฟ้าที่มากขึ้นไดโอดจะทนกระแสสูงได้อย่างไร หากคุณไม่ได้เปลี่ยนมัน
Great question,👍👍
Giving that we are conducting all tests at the high outout voltages, we have not exceeded an output current of 30A. The current diodes used at the output can handle that.
However, these modification allows us to push higher input currents into the coverter - at lower input voltages......thus the increased output power - at higher output voltages.
I hope this makes sense to you.

I have that, plus maybe 5 others....the ones I used in this video are for specific reasons...
They need for the butane soldering iron was explained below. I also talked about my soldering staion in the video 👇👇👇

how come all the free energy creators cant do all these kind of measurements? instead they just light up a light bulb and claim they are making 12kw of free energy.🤔🤔
Great comment!!👍👍👍
Well, they just want to make videos for entertainment and their core audience like their format.
There is a difference between what we are doing and what they are doing....I understand the physics and engineering behind electronics from the theory, design, and test....so, I am not exactly sure what those guys are doing.
To be honest, those fake videos were one of the reasons I became a content creator.
How can you claim you built a high-power machine and you only test it with four 5W LED bulbs?🤔🤔.
Well, we do the hard work and TH-cam gives them the audience..because their content is more entertaining...hahaha.
All good, though. We prioritize honesty and integrity over views.
Thanks again, my friend.

Well it’s because free energy isn’t real.
@@combycat Actually, we have free energy from the sun....but converting that form of energy(solar) to any other form is never a free endeavor. However, in terms of making free energy on our own from any invention, one would have to break the laws of conversation of mass and energy....so in that sense, I fully agree with you 100%.
I love this type of engagement.

Thank you for the quality of your work and your videos. But please try to put black people in images and videos often. You are black, don't forget that. Let us be fair in everything we do.
You have not possibly seen all my videos. I have plenty of videos that show black people. We have a multi-racial community, and there is absolutely no bias in here. We focus on the images that convey a specific relevant illustration that we need for the clip. These are free stock videos and assets, and I am not too picky because the options are
very limited.
