摘要

提出了一种仅使用两个功率半导体开关的低成本单相-三相变换器。该拓扑电路的复杂性是最小的，并且通过使用先进的脉宽调制(PWM)技术，保证了高质量的平衡三相输出电压。该系统的一个独特优点是静态变流器的kVA额定值仅为三相输出kVA的50%。分析和仿真结果表明了该变换器的高性能。还讨论了选择反应组分的设计程序。选定的结果在实验室原型转换器上进行了实验验证，该转换器为三相感应电动机供电。

A low cost single phase to three phase static power converter

A low-cost single-phase-to-three-phase converter using only two power semiconductor switches is presented. The circuit complexity of the topology is minimal, and, with the use of advanced pulse width modulation (PWM) techniques, high-quality balanced three-phase output voltages are guaranteed. A unique advantage of the proposed system is that the static converter kVA rating is only 50% of the three-phase output kVA. Analysis and simulation results are presented to show the high-performance features of the proposed converter. Design procedures for selecting the reactive components are also discussed. Selected results were verified experimentally on a laboratory prototype converter powering a three-phase induction motor.<>
