In order to increase the efficiency of the PWM inverter, the electronic circuit is highly sophisticated with battery charge sensor, AC mains sensor, Soft start facility, output control etc. The PWM ...

The microcontroller’s PWM output drives the inverter with a 1-kHz, 50%-duty-cycle, 0 to 5V waveform. When the PWM output is 5V, it charges C 1.The lower diode in D 1 biases in a forward mode to ...
