Abstract :
A low-harmonic gate-turn-off (GTO) AC-to-DC converter is proposed. The converter can be used as a fundamental input-power-factor compensator in any energized load system. The effect of pulsewidth-modulated (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.<>
