摘要
升压型有源功率因数校正电路不可能将功率因数校正到1,该结论本文将利用PSPICE仿真软件来证明。本文提出了一种能将功率因数校正到0.992的无源功率因数校正新电路,给出了优化后的电路参数,讨论了负载变化对功率因数的影响。
The power factor corrected by means of the active voltage-boosting power-factor-correction circuit is less than 1 and it should be proved in this paper by using PSPICE. Furthermore, a new kind of passive power-factor-correction circuit and its optimized parameters are proposed, of which the highest power factor is 0. 992. And the influence to power factor by load is also discussed.
