초록
Optimal Asymmetrical Pulse-width Modulated (APWM) technique for ac chopper is proposed which can improve the input power factor and eliminate the harmonics of output voltage up to a specified order, and also enables linear control of the fundamental component of the output voltage. The PWM switching patterns at the specified phase angle are obtained by Newton-Raphson method and theoretical comparisons are made with other PWM and APWM technique.
