要約(英語): This paper describes a soft-switching interleaved power factor correction (PFC) converter with a lossless snubber. AC/DC converters require a unity input power factor characteristic with highly efficient operation to prevent the inflow of harmonic current to the power source. The proposed PFC converter improves the input current ripple with interleave control. The converter realizes a high efficiency by the soft-switching operation of all switching devices without a large auxiliary resonant circuit.This paper introduces the soft-switching operation of the converter. In order to confirm the validity of the proposed converter, experiments with a prototype of the PFC converter have been performed. The experimental results indicate that the proposed converter can realize the soft-switching operation of all switching devices, a reduction in the input current ripple, a unity input power factor of 98% or more, a sinusoidal input current, and constant output voltage control. The efficiency of the proposed PFC converter with a lossless snubber is higher than that without the lossless snubber. The results presented in this paper confirm the validity of the proposed converter.
