Abstract
This paper presents a new method to compensate steady-state second harmonic, and it solves the contradiction between steady-state and dynamic performance in single-phase PFC circuit. And anti-windup PI regulator is addressed to improve DSP noise immunity and a method named task-averaged method is presented to increase switching frequency and power density, the achieved switching frequency is 160kHz. In addition, the dual-boost topology is selected for higher efficiency, and the average-current control strategy is adopted to control input line current waveform as well as output DC voltage. The digital controller was validated with the results of simulation and experiment.
