Hi Ttsqas! thanks to share your schematic, but you didn't give the value of the components like resistors :/ Would you make a list of then, including the power the resistors should sustain?
@Khwartz This pwm is sold by my company. Variations of it are being used by several companies. I cannot post the values, The sole purpose of posting the schematic was to dispell Zero Fossul Fuel's insinuation that my pwm was a copy of his.
Diy will not be possible because most of the components are surface mount 0402 package, the pcb has 4 layers, and there are componets on both sides. The 0402s are too small to solder by hand and must be manufactured. The0402s and a 4 layer board were necessary fit all functions on a small area without having to use a micro processor (though I am writing the codes for a microprocessor controlled PWM).
I had to suspend this project because my parents were ill. Also my company manufactures pro audio equipment and I have to finish a guitar preamp, bass guitar preamp, and active direct box by the end of this week. I will return to the PWM next week for sure. I already sent the pcb file to our pcb manufacturer but had them suspend production. Once I give the OK next week it will take maybe 2 -3 weeks for them to run several hundred of the PWMs.
Do I have a working sample? Lol....yes I do that is the only way I could have tested it before sending it off for production. I used a oversized chassis I had lying around to house it during tests but have designed a chassis which I sent out to a chassis manufacturer. I will post videos of the pwm in operation as soon as I receive the stuffed pcbs and the finished chassis. It won't be much longer now.
I should probably mention that I am using a mosfet driver also. So IC1D's output is connected to the mosfet driver's input and the mosfet driver's outputs are connected to the mosfets' gates.

Hi, Will you sell these PMW finished and in DIY form?
Fantastic schematics and work. I like it very much.

Where is power source to connect to cell? is diagram correct? :) Do you have a working sample?
