| 摘 要： | 分析了基于Ｚｅｔａ变换器的功率因子校正（ＰＦＣ）电路；研究了工作在不连续导电模式的Ｚｅｔａ变换器实现功率因子校正的机理；推导出了保证电路实现功率因子接近１的临界电感值。ＳＰＩＣＥ仿真和实验结果都证明了理论分析是正确的，为设计功率因子校正的Ｚｅｔａ变换器提供了理论依据。

| Abstract: | Zeta converter for power factor correction(PFC)circuit has been analyzed and simulated in the work.Near unity power factor is obtained with the high performance circuit,where the converter operates in its discontinuous conduction mode.The critical inductance to guarantee such good behavior is derived,and the mechanism of PFC is also investigated.SPICE simulations show that the power factor is 0.9998 and the total harmonic distortion is 1.776%,which indicates the effectiveness of the theoretical analysis. |
