摘要

UPS、电动汽车或混合动力汽车中的三相逆变器使用直流链路电解电容建立中间直流链路，存在可靠性问题，是逆变器故障的突出原因之一。电解电容器体积大，增加了系统的尺寸和成本。近年来，利用六脉冲调制(SPM)技术与高频功率转换相结合的电解无电容逆变器的研究试图解决这一问题。本文介绍了一种无电解电容逆变器的闭环运行。已经建立了一个1kW的实验室原型，并在不同的负载条件下进行了测试，以验证所提出的分析和实施的控制系统。

Analysis, design, and implementation of closed loop control of electrolytic capacitor-less six-pulse DC link inverter

Three-phase inverters in UPS, electric vehicles or hybrid electric vehicles use dc link electrolytic capacitor to establish an intermediate dc link, which has reliability issues and is one prominent cause of inverter failure. Large volume of electrolytic capacitor increases size and cost of the system. Recent research on electrolytic capacitorless inverter using six pulse modulation (SPM) technique along with high frequency power conversion has tried to address this issue. In this paper, closed loop operation of an electrolytic capacitorless inverter is presented. A 1kW laboratory prototype has been built and tested under different loading conditions to verify the proposed analysis and implemented control system.
