摘要

本文提出了一种简单的无损无源缓冲单元，用于升压变换器，以减轻主功率MOSFET的关断功率损耗，主要是通过关断零电压开关(ZVS)操作和控制器动作来实现。所提出的缓冲电路具有足够的能量恢复或无损操作的潜力，可以提高直流到直流boost功率转换器的性能，从而减少了升压二极管的反向恢复问题、开关瞬态和主开关上的应力

A Passive Lossless Snubber For the Boost Power Converters

In this paper, a simple lossless passive snubber cell is proposed for the boost converter to mitigate mainly turned off switching power losses of the main power MOSFET operated by turned off zero voltage switching (ZVS) operations with controller actions. The reverse recovery problems of the boost diode, switching transients and stresses across the main switch are reduced by the proposed snubber circuit which has enough potential for energy recovery or lossless operations to improve the performance of dc to dc Boost power converters
