基于比例谐振的PFC控制器及其单次谐波抑制

PFC Controller Design and Selective Harmonics Compensation Based on Proportional-Resonant

针对传统PFC控制器中电流环PI参数不易调整等问题,给出了一种新颖的PFC控制器PRBPFCC(Proportional-Resonant-Based PFC Controller),其原理推导明了,形式简单,使得在控制器设计时难度降低。进而,又给出了另一种新型控制器,能够对PFC电流中的单次谐波进行抑制。以上提出的控制器及相关结论都用仿真和实验进行了验证。

In this paper we propose a novel controller PRBPFCC（Proportional-Resonant-Based PFC Controller） is proposed because for the traditional PFC current controller it is difficult to adjust the proportional or integral coefficients.The proposed controller is simple and easy to implement.Then another novel controller is proposed which can realize selectively harmonics compensation.Validity of the conclusions is verified through simulations and experiments.
