If you want to make something, but you get not enouth skills, you can consult with experiensed engeneers throu ICQ. We can draw a schematic, make a prototype, test and optimise it, write a program on microcontroller o computer, write a PC driver for you device.
price 7$/hrs.
ICQ 436686480

We can make one device for you by low price.
 

I am new in SMPS system. I have only theoretical idea (no practical). I have made the 12 Volt 1Amp rating SMPS with ST Viper22 PWM controller and found excellent result. But i want to built SMPS only with discreet PWM current mode controller (UC3844/45) and power mosfet, which is readily available in our market. So I request you to give me circuit schematic with all details of the transformer (core, turns, wire size etc) and design equation of a practically built and tested SMPS ( 12 volt 4 Amp flyback), so that I can built the full proof system easily.

Please tell me the price for provide one prototype board for the same with two extra transformer.

Regards
Jagadish
