    It is a very interesting and professional project based on the ATmega32 microcontroller, I already see such advanced projects in the ATMEL series. Some parts of the circuit are opto-diac MOC3043, MOC3023 with isolated LCD and LED display control (probably rc5) control and many more features...

    600/800W 220~230v AC Inverter SMPS from 12v DC

    First of all you would not used single strands round wire in the working area of over 500hz, Litz or multistrands or flat wire should be used to reduce skin effect. Because high frequency current travels on the outer surface area not the total area of the conductor, so that you need bigger...

    [SOLVED] pic16f72 sinewave inverter with asm codes. not working.

    Thanks Obilaor for your attention, the matter of fact is I use only protues 7.7 therefore I can not provide other than the posted one. To run under 24v battery, you need to change R47 = 6k8 instead of 2k7 rest as it is. Best regards, M Rahman. ---------- Post added at 04:33 ---------- Previous...

    [SOLVED] pic16f72 sinewave inverter with asm codes. not working.

    You are correct Mr.Tipu, LM317 required when you gonna make system for more than 12v. For 12v system you suppose to omit U6 and shot circuit input to output. Rest of the answer Mr.Asif already explain nicely.- Thanks.
