Abstract:

Flyback converter is widely used as low power switching power supply.The efficiency of flyback converter is greatly improved with the introduction of synchronous rectification technology.Based on the principle of self-driven synchronous rectification technology,an improved voltage self-driven synchronous rectification circuit of flyback converter is presented.The design scheme is verified by experiments.

Key words: flyback converter, synchronous rectification, self-driven, power switch
