When the above auto correcting PWMs is integrated with the mosfet gates of any inverter will enable the inverter to control its RMS value automatically in response to the load conditions. If the load exceeds the PWM the inverter output will tend to go low, causing the PWMs to widen. The next idea discusses an op-amp version which can added with ordinary inverters for achieving an automatic output voltage regulation in. The high voltage AC from the transformer output is stepped down using a potential divider network to about 14V. This voltage becomes the operating voltage as well as the sensing voltage for the circuit. The stepped down voltage using a potential divider corresponds.
