摘要

提出了一种补偿稳态二次谐波的新方法，解决了单相PFC电路稳态性能与动态性能之间的矛盾。针对抗绕组PI稳压器提高DSP抗噪声能力的问题，提出了任务平均法提高开关频率和功率密度的方法，实现了开关频率160kHz。此外，为了提高效率，选择了双升压拓扑，并采用平均电流控制策略控制输入线路电流波形和输出直流电压。仿真和实验结果验证了数字控制器的有效性。

The controller of high frequency and high dynamic performance dual-boost PFC module based on DSP

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.
