单级功率因数校正电路的直流母线电压分析和实验研究

Analysis of Bus Voltage of Single-stage PFC Circuit and Its Experimental Research

通过对一种简单的单级PFC电路的研究,从理论上推导出直流母线电压的变化情况,以及电路功率因数和THD的计算公式。

Based on a simple single-stage PFC circuit. the operation prin(?)ple and the variation of the bus voltage of the circuit are analyzed. Then, the formulas of PF and THD of the circuit are getlen. and the theoreltcal analysts is verified by the ev-perimental results.
