Abstract
A low-harmonic GTO ac-to-dc converter with line current lead-lag phase-shift control ability is proposed and analyzed. The converter can be used either as a low-harmonic GTO-controlled rectifier or a fundamental input power factor compensator in a power supply system. The effect of PWM current pulse number on the harmonic contents and converter output voltage control range is investigated. Lower order input current harmonics are eliminated over a wide range, using a specially designed PWM current pattern. In addition, the effect of these PWM current pulse number on power factor compensation characteristic is also investigated. © 1991 IEEE
