Abstract

This work is devoted to influence of snubber circuits to the fast MOSFET switching. Basic phenomena associated with fast switching were described and sources of transistor current and voltage ringing were defined. The most popular methods of limiting overvoltage and suppressing of parasitic ringing of the MOSFET circuit were presented. The main purpose of the research was the impact of snubber circuits on MOSFET switching energy losses analysis, which are very important in high frequency converters.
