Abstract :
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.
