Open publisher page 0 citations

Abstract

This paper designs a switching power with high power factor, which has the standard input 220V AC, and the adjustably output voltage range form DC 30V to 36V, the maximum output current can be to 3A. It designs the main circuit, the PFC control circuit, the measurement circuit, and also calculates the important parameters of these circuits. From the test results, this power has a high power factor,output voltage stability and so on.
