摘要：

This paper presents a new technique to get unity power factor in a single-phase rectifier based on a Buck pre-regulator. The proposed control technique, which employs a feedforward of the output inductor current, allows the use of a small low frequency inductor with a high current ripple. Theoretical analysis, design procedure and experimental results of a 750W, 30kHz prototype; are presented in the: paper.
