Abstract
- A Simple signal compensating strategy for digital inverter is proposed. Because of the non-ideal characteristics from the transformer and MOSFET modules, the output waveforms in positive and negative cycles are non-equaled. This phenomenon will cause the inductive load saturated, and the switches get damaged easily. Thus, the proposed strategy is to combine pulse signal and the reference signal of inverter for adjusting the width and amplitude of pulse signal. The average voltage of the combined signal helps to compensate the DC offset. The strategy is implemented by using built-in low resolution PWM digital controller which has auto adjustment function for the non-equaled output waveforms.
