ABSTRACT:
A switching time correction circuit for electronic inverters controls the operation of power pole switches by delaying the application of each transition point in a reference pattern signal to the output switches. The length of the delay is reduced for transition points in the reference signal which correspond to negative power transitions in the power pole switch and the amount of delay time reduction is proportional to the output current of the respective power pole switch. By inserting a variable delay between the reference signal and the power switch, transition points in the output voltage are each delayed by a fixed time with respect to transition points in the reference waveform pattern.
