Abstract :
This paper presents a novel concept of applying channel interleaving in the boost-type power factor correction (PFC) circuit to reduce the rectifiers reverse recovery loss. The power factor is controlled by the duty cycle ratio of each channel. The phase difference between the channels reduces the turn-on current. Thus, the rectifier reverse recovery problem can be alleviated. Channel interleaving also reduces the input current ripple. This concept can be extended to other PWM-converters
