    [SOLVED] Pic 16f876a Pure Sinewave inverter

    sine wave ccs pic conversor Sorry for the delay, update of last day and today: as there was no feed back from a/b signal so i provided 1.5 volts on pin # 1 & 2 of u10 and inverter started to oscilate but only for the breif period as it was going to standby mode. During this time i measured the...

    [SOLVED] Pic 16f876a Pure Sinewave inverter

    circuit pwm for inverter Thank you for your quick reply. I have simulated the invereter in proteus and after some struggling, achieved the simulated output. I found that my system is lacking the feedback from FET's i,e. a/b which must be from 1-2 volts as you mentioned earlier. i am using...

    [SOLVED] Pic 16f876a Pure Sinewave inverter

    16f876a Hi Mr. Taner, thank you for your great design but i am facing the following problem. After Assembeling inverter and burning the pic, i tried to fire it up. but only red and green led's are blinking alternatively at a 1 sec. interval. I had checked every track and connection and its all...
