摘要

介绍了一种高频电流馈电型有源滤波器在逆变器直流环节中消除电解电容的应用。对有源滤波器的工作原理进行了描述，进行了初步的分析和设计，并对PWM和方波模式下的三相逆变器以及PWM模式下的单相逆变器进行了详细的仿真研究，以证明概念的可行性。研究表明，采用高频有源滤波器消除电解电容不可靠是可行的。

Electrolytic capacitor elimination in power electronic system by high frequency active filter

The application of a high frequency current-fed type active filter for elimination of electrolytic capacitor in the DC link of an inverter is described. The active filter operation has been described, preliminary analysis and design have been made, and simulation studies have been made in detail for a three-phase inverter in PWM and square-wave modes and a single-phase inverter in PWM mode to prove the feasibility of concepts. The study indicates that it is possible to eliminate the unreliable electrolytic capacitor by high frequency active filter.<>
