This paper proposes a controlled approach to be used in power factor correction (PFC) circuits to decrease total harmonic distortion (THD) of input current by eliminating the input current harmonics. This method removes the problems of the conventional PFC converters. Since in conventional PFC circuits the input current is controlled to follow the ac input voltage, it will have the same harmonics...
This paper presents a new method to eliminate the harmonics contents of the input current. In conventional power factor converters the input voltage is assumed to be a sinusoidal wave and the converter switching is controlled such that the input current is aligned with the input voltage. Since the input voltage is not always a sinusoidal wave and may include different harmonics the input current aligned...
