摘要

本文的重点是在有源功率因数校正(PFC)电路中常见的过零电流畸变。首先，导出了量化过零误差的几个方程。然后提出了一种新的切换方案，极大地缓解了这一问题。最后，通过仿真结果验证了所提方法的有效性。采用h桥PFC拓扑。

Elimination of zero-crossing distortion in a power factor correction circuit

The focus of this paper is on zero-crossing current distortion that commonly occurs in active power factor correction (PFC) circuits. Initially, it derives several equations which quantify the zero-crossing error. Then it proposes a new switching scheme which drastically mitigates the problem. Finally, it shows the effectiveness of the proposed method using simulation results. An H-bridge PFC topology is used.
