Abstract
A new control method was proposed by Hunyar et al. (1994) for PWM IGBT AC chopper. The discussed application field was the energy-saving control of an induction motor. Some new fields have been found since that time: compensation of unbalanced voltage supply; filtering the upper harmonics; series compensation; and excitation of brushless motor. The emphasis is on the first two points. In this paper, different methods are developed for these purposes. These are simulated, examined and presented in more detail in the paper. The best one is selected, implemented and tested
