Design of a Low-Power Flyback Switching Power Supply

Abstract:

This paper designs a low-power flyback switching power supply using current-mode PWM control chip UC3843. The design of control circuit and high-frequency transformer’s parameters of single-ended flyback converter is given. Simulation model of switching power supply is established by saber software. Simulation result shows that the power supply both have a good line regulation and load regulation with high efficiency, and verifies the correctness and feasibility of the design scheme.
