Design and development of 100 w AC-DC flyback converter

Abstract

This project basically is to design, built and develop 100 W AC - DC flyback converter. This circuit is design by using PSIM software. It is design for universal AC line input and the circuits will be test under various stated conditions. This Switch Mode Power Supply (SMPS) has the input voltage range 110 - 220 V AC and provides a nominal 12 V, 8 A full load DC output. The design uses a flyback converter topology, with a PWM controller UC3844AN as the main switch and control device. Switching frequency varies according to line and load condition. The project has a rated power of 100 W and a frequency range about 50 - 60 Hz. The main objective of this project is to compare value of voltage and currents from calculation and simulation by using Power Simulator (PSIM) software and obtain constant output, high efficiency and frequency range from the hardware either using specification of Malaysia Standard (MY) or America Standard (US).
