I'm trying to design a sine wave inverter based on Switch Mode technology. I tried many circuits. each of them creating problem. now the latest one was like this:
Mosfets are protected via that fuse from burning. I am using 1A fuse there. Fuse is burning again and again. I don't know why. I fetched this same problem before but found no solution.
MCU pic16f73 is generating two PWM signals like:
what is the problem and what is the solution?
again I tried with another one. But in that circuit NE556 is not generating any clock pulses. I checked PCB diagram again and again, but still can't find then ans. But the DC/DC converter portion is working fine.
the circuit is:
and my DC/AC converter portion is:
Now the question is why all these faults happening???
