DESIGN OF FLYBACK CONVERTER WITH POST REGULATOR (TWO OUTPUTS, 8 W)

ABSTRACT DC-DC converter is the essential part of any satellite for providing power to high definition cameras and sensitive sensors and other small devices. These devices require constant low dc voltage and varying load current which can be provided by isolated DC-DC topologies. Some ICs are also available which can provide the required constant low voltage but they are cost effective. So the paper includes the design and Simulation of Flyback converter (Two Outputs, 8W). Design calculations of Flyback converter presented in this paper. Design is also simulated in PSPICE simulator with a switching frequency of 150KHz. Simulation results of close loop and open loop are also presented and discussed Keywords: Flyback Converter, Isolated Buck – Boost Converter, PSpice Simulator, Multiple Output Converter, DC – DC Converter, Post Regulation, Closed Loop
