A Novel Method of UC3842 used in Flyback Switching Power Supply

Peng Fang-zheng

Abstract

This paper presents a novel flyback switching power supply in which a intelligent integrated chip named UC3842 is used.A new usage of UC3842 in flyback switching power supply is provided to perform feedback from output directly.Compared with traditional circuit,it has lower output voltage ripple,lower load adjustment rate and lower input voltage adjustment rate. The experimental results verify the virtue of this method.
