| Abstract: | A kind of PFC＋PWM Converter is designed based on ICE1CSO2. The circuit is composed with a PFC converter for the first stage, and a two-transistor forward converter for the second stage. According to the analysis and simulation on the circuit, the main transformer is analyzed and designed based on a 500 W experimental converter, and high power factor, stability and efficiency is verified on this circuit. |
