Abstract

The DC power supply is an important device in substations,it can supply uninterrupted power for load,the high frequency switch mode power module must have function of power factor correction.Based on new DSP chip MC56F8025,a digital active power factor correction rectifier with soft switch characteristic was designed,the process of system design was described.At last a 2.2 kW prototype was built to verify the favorable performance resulted from digital control.
