efficiency of this converter is about 79% as i have tested

@@innovationic convert 12v 3A to 5v 6A possible??

upto 50 meters

maximum can be 60W to 100W

The PC817 optocoupler is for voltage feedback, with the transformer’s primary and secondary coils each having 16 turns.

In this video, I demonstrate how to control DC motor speed using an XL6009 DC-DC converter. By rotating the potentiometer, you can adjust the output voltage, which directly controls the motor's speed. This method offers precise and efficient motor control.

@@innovationic Yes...I know what you are doing and no you are wrong. Precise and efficient...no not hardly! A DC-DC converter with an adjustable output voltage is starving the motor. It can't run at full torque at anything other than whatever is the max output voltage. Anything less and the motor is receiving too little current to develop max torque. This is the genius of PWM based ESC's! They apply full amps and volts to the motor always. All they adjust is HOW LONG it is applied. AS a result the motor is almost always running at full torque. Yes...sure...under no load...you can adjust the RPM of the motor with adjusting the voltage. Good luck doing that under load! For that you need a PWM ESC. *** You are a smart guy. You ought to know about PWM motor control. I'm surprised that you think adjusting voltage is how you control motor RPM under load. You won't find a brushed variable speed drill or any other brushed motor tool on the planet that adjusts voltage! They 100% do it with PWM. *** Ironically, if you had that PICO o-scope connected to your DC-DC, you'd see that it too is adjusting output voltage via PWM. Pull the output filtering cap or check signal before the output schottky diodes so you can see what the DC-DC IC is doing right at it's output. You will see that it's making PWM of some kind. *** If you are running the motor direct from the DC-DC IC's output leg with no filtering, then you are feeding the motor actual PWM and that's very much the same thing as a brushed ESC. If so and I misinterpreted what you are doing, I apologize. I do make mistakes...it's normal for us humans! *** There's very good reasons for PWM control for lots of things: 1. You are feeding the motor full amps and volts all the time. All you are adjusting is how long you feed it vs how long you aren't feeding it. More time with full power and the motor spins faster. Less time with full power and it slows down. 2. Mosfets and transistors work similarly in a few key ways. They both have a linear region where they act like a potentiometer and can be adjusted via the gate or base to have more or less resistance across the main junction. Resistance = heat and you want that as minimal as possible. 3. Mosfets and transistors both have a fully saturated state where they can't be turned on more. In this state the main junction is at it's lowest possible resistance and therefore making the least amount of waste heat. 4. PWM...aka turning the mosfet or transistor on and off in its saturated state creates the least amount of heat in the power components. This increases efficiencies and makes electronics live longer lives. Even audio amplifiers now days are almost all Class D or PWM driven instead of operating the power electronics in their linear regions where they make the most waste heat.

yes these days digital electronics is used in wide range

You're absolutely correct. Pin 13 output control can be configured for either push-pull or parallel operation. In this scenario, pin 13 will be connected to GND for optimal performance.

@@innovationic is there any updated circuit provided by you ? .. i saw your lots of videos and really fascinated with your hard work.... also your crisp and detailed explanation and quick reply helped me to update my circuits. great job 👌👌👌

thankyou the update in this circuit is just connect the pin 13 of TL494 with GND that's it 👍

"The video is in English. Let me know if you need clarification on any part!"

@@innovationic Well actually speak it

Thanks for the feedback!

To ensure safe operation of the LM7812 with 35v input voltage, diodes can be added in series to drop excess voltage before the regulator

@@innovationic sry for miscomunication actually i want to use this buck boost with max input voltage of 35 volts... is it ok to give this high voltage to TL494 .. i found lm7812 has max input of 24 volts so it cannot be use... i also has one buck boost with uc3843 whose input is also limited .... for the safe operation of PWM controller what regulator should i use

you can try LM2596 buck converter or make auxiliary winding for driving TL494 just like smps

@@innovationic ok thanks

yes its premade pcb for driving led from 7W to 18W

ya sure you can calculate the number of turns based on ferrite core transformer

thankyou

it looks like you are building inverter

the use of resistor between pin 1 and 2 to stabilize the feedback loop as pin 1 is the compensation pin

okk i will do

this converter do both boost and buck so for step down just adjust preset

I am using AJ-SR04M waterproof sensor in my tank as it also have same pinout as HC-SR04. here is the link of this waterproof sensor - www.ebay.com/itm/373964657289?mkcid=16&mkevt=1&mkrid=711-127632-2357-0&ssspo=ljx3rwarrzo&sssrc=2047675&ssuid=&widget_ver=artemis&media=COPY

@@innovationic what should i do if i'm using hc sr04 my brotha?

using SR04 in water tank damages the sensor, so I tried to waterproof the sr04 with plastic rapper or box enclosure but anything didn't works as ultrasonic wave reflects back from the enclosure so you need to use the waterproof version currently I have installed the AJ-SR04 in my tank thankyou

@@innovationic yup, so i have to give up using hc sr04 😀 txu my brotha

welcome

thankyou for watching as this circuit I made with the use of NE555 IC for low battery cutoff protection but its not works perfectly for that watch this upgraded version - th-cam.com/video/HL9gfEzcwbw/w-d-xo.html in this circuit I have used PC817 based very simple logic for low battery cutoff

Watch this ferrite core transformer video this will help you - th-cam.com/video/hFvyCh5-HPE/w-d-xo.html

Thanks

yes input ranges from 9v to 30v and output can from 1.2v to 80v

Yes here is the link of gerber file - drive.google.com/drive/folders/1Wo-_KzmKNqCGDqpQ9fq_wMOO2qYkpfMy?usp=sharing

@@innovationic thank you🙏

the nominal capacitors are rated of 10V 1000uF, diode 1N4007 and the AMS1117 3.3V LDO smd regulator for NRF24 module

thanks 👍

yes easily and peak to peak upto 3A

I see it features same property as the 49E so you can use this to your project

thankyou very much

yes it can be used for 50Hz and 60Hz inverter driver and also for converting 12v to 300v DC i.e. high frequency inverter, its range is wide from 30Hz to 135Khz thankyou

output me load connect karne ke liye 12v aur mosfet drain pin se load connect hoga

@@innovationic ok does that mean mosfet drain pin will act as -ve. Sorry I am from a different field but I want to make galvanostat and I liked your video. Just want to confirm before I start making.

watch this - th-cam.com/play/PLgl9JJrc5AoH-b3oZtFfuM3JNE1esPqy1.html

for 48V dc use converter 48V to 12v for this module and connect voltage sense pin to 48v with voltage divider circuit

most welcome

Thanks

No, this circuit is only for SG3525 thankyou

thankyou for watching circuit is already available in discription - drive.google.com/file/d/19fSnwtTA-3ocw5DT5jXTYdKhupo4xgfm/view?usp=sharing

@@innovationic Thanks for sharing

thankyou for watching circuit diagram is already available in discription - drive.google.com/drive/folders/1C2Erm8nLnHzn2ifuRhZTFsQLLfs6P2Zh?usp=sharing

I think you should go for SS49E, its easier for controlling

@@innovationicok, why? What‘s the difference in detail?

as SS49E or 49E is analog hall sensor so for controlling rpm of motor you need throttle so you can make structure to place 49E with circular magnet to control them

Why is ss49e easier for controlling? Unterstand, i need to copy the design of a circular throttle control element and miniaturize it, and try to panel-mount it (wanna use it for a mini lathe rpm control)

watch this video it might helpful - th-cam.com/video/CYDoM9iL90o/w-d-xo.html

Yes I will

watch this video - th-cam.com/video/WzPd7IcPp8w/w-d-xo.html

thankyou 👍

both SG3525 and TL494 have pros and cons, the TL494 consists of two op-amp which has benifit of controlling voltage and current, on the other hand SG3525 have single op-amp which controls the voltage only. So if you are building DC-DC converter then TL494 are good for CC & CV while SG3525 is good for inverters or other purpose

yes but in this modification I have used A3144 digital hall sensor

does it work without resistors ?

current limiting resistor is necessary for base of Transistor

ok thanks for the reply

you can use higher capacity capacitor like 470uF or 1000uF this makes output stable

thankyou for watching the circuit is correct but in layout the diode is in wrong connection so I have updated it - drive.google.com/drive/folders/1sH-_ll4g7CyGi7784l6jgv9JSg5OUe59?usp=drive_link and if the mosfet is heating then make sure you have connected the transformer in correct way, its basically a flyback converter so the primary coil is opposite to secondary coil.

most welcome

thankyou brother
