摘要

本文提出了一种改善三相抑制链路整流器-逆变器输入电流总谐波失真(THD)和功率因数的新方法。该方法采用了一种新型可控二极管整流器。本文阐述了该方法如何使整流-逆变交流电机驱动工作在宽功率范围内，功率因数接近统一，谐波较低。对采用新控制方法的电路进行了分析。该拓扑的主要特点是成本低、体积小、效率高、结构简单。

A novel near-unity power factor AC drive

In this paper, a new method of improving the input current total harmonic distortion (THD) as well as power factor of a three-phase suppressed-link rectifier-inverter is presented. This proposed method makes use of a novel controlled diode rectifier. This paper illustrates how the proposed new method can enable a rectifier-inverter AC motor drive working in a wide power range with near unity power factor and low harmonics. The analysis of the circuit with new control method is described. The main features of the topology are low cost, small size, high efficiency and simplicity.
