A Passive Lossless Snubber For the Boost Power Converters

Abstract

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
