Abstract

A high-performance control method for a voltage-type pulsewidth-modulated voltage-type converter is introduced. Starting from the modeling of the converter, power-factor control and five types of DC voltage control are discussed. The stability and responses of these control methods are analyzed and compared with the root locus method and by digital simulation. The most promising approach, which uses current feedforward control, is applied to the drive test of an induction motor, and its excellent performance is confirmed.<>
