I've testes changing the rectifying diodes with a stronger one (2x20A to 1x90A) and changed its fan for a more cappable one one (while adding two other small fans on its side to inprove airflow). I was capable of drawing +45A@~36V and reached +30A@52V while keeping the mosfet under 70ºC. if your solution and mine were to be combined it might be able to surpass 2000W at 30V input...
You're welcome! I also did some other minor changes, such as adding another shunt (as you did) and changing the current trimpot value for a 1kOhm one... but the main changes were those. One thing we did noticed and still find very unsettling is how, after a few minuts of going under intense load, the dcdc seemed to actively limit its input current to around 40 A, we still have to figure out why, it might be our batteries getting discharged or something around that... but further tests must be taken... @@theinnovati0nlab782
Friend, then I do want to be able to connect in parallel without them happening like what happened to you. Should I put some blocking diodes at the end of each one?
It doesn't help. If you really watched the video, you should have seen that those converters were diode ORd at the output ......the same thing you are suggesting. It doesn't work for high power applications. If you are looking to double your output power by connecting these converters in parallel by diode 'OR'ing them, it won't work. However, I never discourage a diy adventure as they are usually the best way to learn. The Innovati0n Lab💥
@@theinnovati0nlab782 I need soon to do a project. I prefer that you advise me. Yes I have 2 of 40 amp and 1800 w. What is the best way to connect them in parallel without damaging them? to get an output of about 1500 to 2000 w at 54 v output... thank you
Great short video! Can you get a temperature reading of the mosfet and inductor? 1770W in and 1510W out means ~200W is going somewhere? I wonder where??
Of course! That is a very reasonable statement. The dissipated power is usually distributed across all the major components. 💥Quiescent power - control circuit power consumption and dissipations 💥Power Inductor - core and copper losses. 💥MOSFET - Vgs*RDSon dissipation. 💥Rectifier Diodes - I(f) * V(F) Output filter caps: ripple losses I can probably calculate all of this in my head...lol We know that there are power losses due to dissipation.....the fight is to figure out how to minimize the losses through design optimization. Very wonderful feedback! Very constructive!👍👍👍 I am happy that we have very experienced ans knowledgeable people in our audience. Thanks again. 👍😎 - The Innovati0n Lab💥
The inductor core will be the highest heat load. The mosfets will have a lot less heat, but it's critical that it does not build up too much. Modded one similarly to drive a laser diode stack that needed 22 to 40A while using a 48V cell site power supply. In other words an easy way to avoid using very expensive power supplies.❤

What the advantages of those special toroidal core that you are use over standard core? Does EE or ETD core with an air gap is suitable for this apppication? And even though iron powder core can be used here since you use 22KHz you seems to avoid it. Is it too lossy or there is another reason to not use it?
Nothing really too special about them. Those are ferrite powder cores. The idea was to stack a few of them to increase the net saturation current. I prefer to use the EE or EI core for actual transformer designs - especially for comverters where input to output isolation is a design objective. You are correct, gapping helps with those in terms of extended ingredients, the saturation currents. 👍😎 The Innovati0n Lab💥
Thanks for the wonderful feedback. I greatly appreciate it.👍👍👍 I see your point, and you are correct. However, the circuit operates around a very delicate balance. It's hard to explain over text. But I will try. We always have to pay close attention to the current, voltage, and power dissipation ratings of all the major components. For example, adjusting the trim pot value could trick the PWM controller to push for a higher duty cycle, but this could push the power inductors beyond their rated saturation current.....and when this happens, your inductor looses the ability to store energy in its magnetic field during the switching or On-state of the PWM....then the inductor becomes more of a dead weight shunt to your MOSFET...and wala, we have some nice blue smoke - but as long as we capture it on camera, then that is Gold...hahaha! If you are lucky, your fuses will blow first, but that rarely happens because MOSFETs and other solid-state switching devices have faster response times than fuses. I hope this makes sense to you. 👍😎 The Innovati0n Lab💥
@@theinnovati0nlab782 yes, you are correct.. I had blown my mosfet caused by change the trim resistor too big.. so, I limit only 2x value existing trim resistor. And my boost converter still "a live" untill now for charge 83v lithium battery
No worries, I am currently working on it. My videos take quite some time to make. What you see in my videos are usually recorded real tests and analyses of an ongoing project. Stay subscribed, my friend.😊 👍😎 The Innovati0n Lab💥
Just to get a clearer picture, how about as in my case,, if i am stuck with an inverter having mppt operating voltage range of 30-80v, and where I cannot make series connection of 400w panels as it exceeds 80v, and if hooked in parallel, I get the drop in voltage from 40v to 30v very early (30 being the minimum limit of mppt range) thus introducing a bottleneck to the production from solar, with this device maybe I can increase the output of solar voltages at a sweet spot for example 60 or 70v ( from 40v of solar, while connected in parallel) to remove the bottle kneck, right now I am getting 800w from x4 450w solar panesl instad of +1400w which is max possible production throught mppt of the inverter,
Well, I didn't see a question - it looks like you got it all figured out....time for an experiment! The only thing I can tell you is that you should never try to take any shortcuts with your solar design - if you do, you will pay the heavy price of damaging something.⚠️⚠️ You are seeing a resultant voltage drop when you connect the solar panels in parallel because the panel with the higher Voc (Open circuit voltage) is being shorted by the channel with a lower Voc....you do not want this to be happening as you will end up overloading both panels with each other. You need to connect your panels in series, then to an MPPT charge controller that will charge your battery....then, your battery will now be used to drive your power inverter. 💥💥💥 Design flow: Solar irradiance.....=>Solar panels......=>MPPT charge controller........=>Battery bank.....=> Power inverter.....=>LOAD💥 You should always follow this flow UNLESS you are using a grid-tie inverter.
Great question. I don't do reverse engineering because it it unethical. What I have been doing with these converters is simply to make modifications to them to see how we could make them perform better....that's it. In my upcoming video, I will provide the schematic for what I did - but not for the board. Also, boost converters are really simple for me to design, why suffer through the headaches of reverse engineering. Stay tuned, my friend. The Innovati0n Lab💥
Great question.👍👍👍 It really depends on what you are working with or where you are getting the DC power from. If you are talking about and AC to DC power supply, the most affordable or most feasible thing to do will be to go buy one of those used server power supplies that I used in this very video. They can give you a very well regulated 12V output at 65A of output current.....only for about $20 or so. However, if you are talking about a DC-DC power supply, that is another story.. I hope this helps. - The Innovati0n Lab💥

OUTSTANDING...You can go far in the future...can't wait for the next one!!! Have you thought of a high VOLTAGE say, 12-15v TO ~500v at large current for fast charging electrolytic capacitor banks? --dalE
Thanks a lot! I appreciate the great feedback, as always.👍👍👍 As for your high voltage design suggestion, the concept is simple, I have actually built a 12 to 240V DC-DC converter a while ago - as a booster stage to a transformerless power inverter. More of the work is in designing power transformers with great input to output isolation and minimum losses. Also, 500V requires special test and safety equipment. I am always very cautious while playing with high voltage projects on TH-cam because I don't want to set the wrong precedent for our audience. When I am ready for it, I will do the diligence to stress on safety, test equipment, and PPE. 500V DC is quite lethal and I have to make sure that the fact is well communicated to our audience.😊 But this project is now on my bucket list.

You are on the right track, but there are more things to consider. But I would like to engage with you on this subject. Please elaborate - if you don't mind. The Innovati0n Lab💥
@@theinnovati0nlab782I’ve looked far and wide for larger input terminals for this converter and for other products (Atorch DL24, XY6020L, etc) It seems like the pin pitch limits the amperage rating. I think when looking at the 5.08mm pitch terminals I couldn’t find much rated over 20A. Don’t think there was anything rated for 40A. Obviously with some serious modding you could use a different connector. Like the terminals on some BMS’s that allow you to just place a lug on it since it is a table shape with a threaded hole on the top of the table. Looking for something like that to be able to use higher currents on some devices and others I just want beefier wires
@ericklein5097 This is wonderful feedback. I did check a long time ago, and my research showed that the input and output terminal blocks/connectors should be able to support greater than 60A. I will double-check on this - maybe I looked at the wrong datasheet. However, giving the short run between the board and the connectors, you should still be able to push alot of power through the pins - the only issue is that you will encounter more dissipation due to conductor resistivity. Thanks again for reminding me to take a second look at this. Much appreciated. 👍😎 The Innovati0n Lab💥 www.theinnovati0nlab.com

Yes, would like to see the a in depth video on this hack.
Awesome!
Already in the works.

You can try change the value of trim resistor current constant, the ouput current will little increase..
Thanks for the wonderful feedback. I greatly appreciate it.👍👍👍
I see your point, and you are correct. However, the circuit operates around a very delicate balance. It's hard to explain over text. But I will try.
We always have to pay close attention to the current, voltage, and power dissipation ratings of all the major components. For example, adjusting the trim pot value could trick the PWM controller to push for a higher duty cycle, but this could push the power inductors beyond their rated saturation current.....and when this happens, your inductor looses the ability to store energy in its magnetic field during the switching or On-state of the PWM....then the inductor becomes more of a dead weight shunt to your MOSFET...and wala, we have some nice blue smoke - but as long as we capture it on camera, then that is Gold...hahaha!
If you are lucky, your fuses will blow first, but that rarely happens because MOSFETs and other solid-state switching devices have faster response times than fuses.
I hope this makes sense to you.

@@theinnovati0nlab782 yes, you are correct..
I had blown my mosfet caused by change the trim resistor too big.. so, I limit only 2x value existing trim resistor. And my boost converter still "a live" untill now for charge 83v lithium battery
Great bro
Thanks a lot, bro!!

Good evening
Please can you share uts circuit diagram in details.. i need this ,, this wonderful
Wonderful, I am glad you like the design.
Please stay tuned.
hi again, :)
How long before you can prepare and post the full modding video?
No worries, I am currently working on it. My videos take quite some time to make.
What you see in my videos are usually recorded real tests and analyses of an ongoing project.
Stay subscribed, my friend.😊

Just to get a clearer picture,
how about as in my case,, if i am stuck with an inverter having mppt operating voltage range of 30-80v, and where I cannot make series connection of 400w panels as it exceeds 80v, and if hooked in parallel, I get the drop in voltage from 40v to 30v very early (30 being the minimum limit of mppt range) thus introducing a bottleneck to the production from solar,
with this device maybe I can increase the output of solar voltages at a sweet spot for example 60 or 70v ( from 40v of solar, while connected in parallel) to remove the bottle kneck,
right now I am getting 800w from x4 450w solar panesl instad of +1400w which is max possible production throught mppt of the inverter,
Well, I didn't see a question - it looks like you got it all figured out....time for an experiment!
The only thing I can tell you is that you should never try to take any shortcuts with your solar design - if you do, you will pay the heavy price of damaging something.⚠️⚠️
You are seeing a resultant voltage drop when you connect the solar panels in parallel because the panel with the higher Voc (Open circuit voltage) is being shorted by the channel with a lower Voc....you do not want this to be happening as you will end up overloading both panels with each other.
You need to connect your panels in series, then to an MPPT charge controller that will charge your battery....then, your battery will now be used to drive your power inverter.
💥💥💥
Design flow:
Solar irradiance.....=>Solar panels......=>MPPT charge controller........=>Battery bank.....=> Power inverter.....=>LOAD💥
You should always follow this flow UNLESS you are using a grid-tie inverter.
did you reverse engineering the Chinese Bord ? , if you may i need the schematics , thank you
plz share with us , really appreciate your effort
Great question.
I don't do reverse engineering because it it unethical. What I have been doing with these converters is simply to make modifications to them to see how we could make them perform better....that's it.
In my upcoming video, I will provide the schematic for what I did - but not for the board.
Also, boost converters are really simple for me to design, why suffer through the headaches of reverse engineering.
Stay tuned, my friend.

❤❤❤❤❤Sir, I liked your video. Can you tell me which Mosfet you have installed in it? Please give the number of Mosfet.
Thanks a lot for the wonderful feedback! 👍
MOSFET ==> HY3912.
Thanks
Is any way to boost current!?!
Because I have a power supply with 12volt 4amp, need to convert 12volt to 10amps, ; is any way
Great question.👍👍👍
It really depends on what you are working with or where you are getting the DC power from.
If you are talking about and AC to DC power supply, the most affordable or most feasible thing to do will be to go buy one of those used server power supplies that I used in this very video.
They can give you a very well regulated 12V output at 65A of output current.....only for about $20 or so.
However, if you are talking about a DC-DC power supply, that is another story..
I hope this helps.

High friend please what the video below to see if you could find some good information out of it.
But will need MOSFETs, fast recovery diodes, and output capacitors that are high voltage rated.

Good morning
The Innovati0n Lab, I am a new subscriber to the community
The Innovati0n Lab. I would like to try to reproduce this boost converter in a learning context, please help me with the diagram of the electronic assembly of the project
Thanks for the wonderful!
I love people with curious minds!👍👍
However, I have a very strong ethical conviction against reverse engineering someone else's work/design. All I am doing is to find ways to make these converters perform better. In a nutshell, I do not have the design schematics for the converters, so I won't be of much help if you are looking to reproduce them.
On the other hand, I am working on our own design, and I will be sharing some updates on it soon.
See the video below.

@@theinnovati0nlab782 I thank you for answering me, thank you from the heart once again. I then watch over the future project
OUTSTANDING...You can go far in the future...can't wait for the next one!!!
Have you thought of a high VOLTAGE say, 12-15v TO ~500v at large current for fast charging electrolytic capacitor banks?
--dalE
Thanks a lot!
I appreciate the great feedback, as always.👍👍👍
As for your high voltage design suggestion, the concept is simple, I have actually built a 12 to 240V DC-DC converter a while ago - as a booster stage to a transformerless power inverter. More of the work is in designing power transformers with great input to output isolation and minimum losses. Also, 500V requires special test and safety equipment. I am always very cautious while playing with high voltage projects on TH-cam because I don't want to set the wrong precedent for our audience. When I am ready for it, I will do the diligence to stress on safety, test equipment, and PPE. 500V DC is quite lethal and I have to make sure that the fact is well communicated to our audience.😊
But this project is now on my bucket list.
Stay tuned, my friend!
Thanks again.

Nice,these work. Thanks for you give me knowledge.I have no idea boosted power converter efficiency so you can better for used some mosfet, capeciater,s . Thanks🎉
Thanks a lot for the wonderful feedback, my friend!👍👍👍

Can you provide me it,s boosted power .
I have tested it to about 1740W at an input voltage of 48V.
TH-cam ghost un subscribed me, I got some catching up to do. Thanks for great videos and info.
Thanks a lot for the feedback.👍
That is weird, I am not sure why that would happen.
The biggest limit of this boost converter is it´s input terminal and the input undervoltage protection mosfet
You are on the right track, but there are more things to consider.
But I would like to engage with you on this subject. Please elaborate - if you don't mind.
The Innovati0n Lab💥
@@theinnovati0nlab782I’ve looked far and wide for larger input terminals for this converter and for other products (Atorch DL24, XY6020L, etc)
It seems like the pin pitch limits the amperage rating. I think when looking at the 5.08mm pitch terminals I couldn’t find much rated over 20A. Don’t think there was anything rated for 40A.
Obviously with some serious modding you could use a different connector. Like the terminals on some BMS’s that allow you to just place a lug on it since it is a table shape with a threaded hole on the top of the table. Looking for something like that to be able to use higher currents on some devices and others I just want beefier wires
@ericklein5097
This is wonderful feedback. I did check a long time ago, and my research showed that the input and output terminal blocks/connectors should be able to support greater than 60A. I will double-check on this - maybe I looked at the wrong datasheet.
However, giving the short run between the board and the connectors, you should still be able to push alot of power through the pins - the only issue is that you will encounter more dissipation due to conductor resistivity.
Thanks again for reminding me to take a second look at this.
Much appreciated.

Can you elaborate a little? Are you asking about why DC-DC vs AC to DC through rectification?
