摘要：

A passive lossless snubber is proposed in this paper to reduce switching losses and EMI noise by restricting di/dt and dv/dt of the switching device. As an example, a boost convertor with the lossless snubber is presented to illustrate the operation principle and theoretical analysis in details. Six basic DC/DC convertor topologies equipped with the proposed snubber are also shown in this paper A 5kW power factor correction (PFC) prototype with the snubber is designed to show the advantage of the snubber. Both of simulative and experimental results are given.
