Abstract
A system and method for controlling a DC to AC voltage inverter. The system and method include an inverter for generating a pulse width modulated (PWM) waveform to convert a DC input voltage to an AC output voltage suitable for use with a non-linear electrical load, and a signal generator for generating a AC output voltage signal representing the AC output voltage. The system and method further include a processor for processing the AC output voltage signal to select the PWM waveform, and a control signal generator for generating a control signal based on the PWM waveform selected operative to control the inverter for generating a PWM waveform.
