Abstract
A controller for an inverter provides variable gain control in a voltage regulation loop to prevent overshoot in an output voltage of the inverter. A feedback circuit senses the output voltage and provides a voltage feedback signal to the controller. The controller includes a voltage conversion circuit and an error amplifier as part of the voltage regulation loop. A gain control block varies a circuit parameter in the voltage conversion circuit or the error amplifier such that regulation of the output voltage starts at a relatively lower voltage level and increases smoothly to a desired level.
