Abstract

The use of some integrated circuits in an SMPS circuit are the main factor that increasing the cost. Self-oscillating feedback converter topology is a well-known circuit topology for low-cost application without using any single integrated circuit chip. In this paper, a Low Cost with high efficiency converter without any single integrated circuit component was analysed and designed. It has also multiple outputs of 3.3 V/1 A, 5 V/0.5 A, and 12 V/0.1 A so that it can be used as power supply for DVD player. Experiment results showed that it can deliver continuously output voltage as designed and a total output power of 7.3 W, with an efficiency for about 70%.
