摘要
提出了一种具有恒功率控制的单级功率因数校正电路。该电路功率因数校正级工作在电流断续模式,具有较低的总谐波畸变和较高的功率因数。该电路的直接能量传递方式降低了直流母线电压并且提高了电路的效率。采用恒功率控制方式使得电路具有良好的输出特性。并通过仿真和实验结果证明了电路的可行性。
A novel single stage power factor correction converter with constant power control is presented. The PFC stage operates in discontinuous current mode (DCM) to achieve low THD and high PF. A direct energy forward method and a constant power control strategy are employed to achieve low bus voltage, high efficiency and good output characteristics. It is verified by simulation and experiment results.
