对于容量较小的小容量整流电路，如消费类电子产品和电器，一般采用电容输入型整流电路。因此，电力系统内产生的各种谐波成为一个严重的问题。关于这一效应的各种研究以前已经提出过。然而，其中大多数采用开关器件，如场效应管等。没有开关设备使系统更能容忍过载，并带来低无线电噪声的好处。我们提出了一种功率因数校正方案，使用倍压整流器而不使用开关器件。在该方法中，输入电流分为两个周期，其中一个周期为小输入电容充电，另一个周期为大输出电容通过大电感充电。通过将输入电流分为两种不同的模式，可以拓宽电流的传导周期，并且可以在很大程度上消除两种模式之间的谐波。因此，谐波特性可以得到显著改善，从而大大减少低阶谐波，例如五阶和七阶。理论和实验结果都证实了这一结果。
For small capacity rectifier circuits with a small capacity, such as those for consumer electronics and appliances, capacitor input type rectifier circuits are generally used. Consequently, various harmonics generated within the power system become a serious problem. Various studies of this effect have been presented previously. However, most of these employ switching devices, such as FETs and the like. The absence of switching devices makes systems more tolerant to over-load, and brings low radio noise benefits. We propose a power factor correction scheme using a voltage doubler rectifier without switching devices. In this method, the input current is divided into two periods, where the small input capacitor is charged during one period and the large output capacitor through large inductor is charged during the other. By dividing the input current into two different modes, the current conduction period can be widened and harmonics can largely be canceled between the two modes. Hence, the harmonic characteristics can be significantly improved, whereby the lower order harmonics, such as the fifth and seventh orders, are much reduced. The results are confirmed by theoretical and experimental implementations.
