Abstract
A single-phase buck rectifier applying pulse width modulation (PWM) creates a large amount of low-order harmonics flow out in the input current. A high-inductance inductor must be used to reduce the pulsations of the DC inductor current and to produce a sinusoidal input current. To address this, the authors propose a single-phase buck rectifier with improved input current waveform by adding a switch for back flow of the DC inductor current to the conventional structural elements. In this paper, the main circuit configuration and operating theory of the proposed rectifier are explained, and its effectiveness is confirmed through experimental results and simulations. © 2006 Wiley Periodicals, Inc.

改进输入电流波形的单相降压整流器的稳态特性
采用脉冲宽度调制(PWM)的单相降压整流器会在输入电流中产生大量的低次谐波。必须使用高电感电感来减小直流电感电流的脉动并产生正弦输入电流。为了解决这个问题，作者提出了一种单相降压整流器，通过在传统结构元件上增加直流电感电流回流开关，改善了输入电流波形。本文介绍了该整流器的主电路结构和工作原理，并通过实验和仿真验证了其有效性。©2006 Wiley期刊公司电子工程学报，2009,31 (4):559 - 559;在线发表于Wiley InterScience (www.interscience.wiley.com)。DOI 10.1002 / ecja.20330
