초록
New asymmetrical PWM AC Chopper is proposed, which can improve the input power factor and can reduce harmonic contents at both its input and load sides. The switching scheme for the proposed technique is presented and the theoretical characteristics of AC voltage regulator controlled by APWM AC chopper are investigated through the digital simulation
