A zero‐current transition (ZCT) pulse‐width modulation (PWM) interleaved boost power factor correction (PFC) converter with a ZCT auxiliary circuit is presented to achieve ripple current cancelation and ZCT for power switches. The proposed PFC converter adopts a ZCT auxiliary circuit to realise ZCT for power switches and diodes . Thus, the switching losses of active power switches are reduced and the reverse recovery losses of power diodes are eliminated. The interleaved PWM control scheme with constant frequency and constant duty cycle is used in it. Thus, the control circuit is simple and the circuit cost can be reduced. It shapes a close sinusoidal input current waveform, so that an input current waveform with low harmonic can be obtained. The operational principle and design consideration are discussed in detail. Finally, experimental results taken from a 1000 W prototype are presented to confirm the effectiveness of the proposed PFC converter.
