使用电力电子转换系统的现代工业装置需要改进负载侧输出电压波形以满足各种操作负载条件的需求。本文提出了一种新型的串联谐振正弦波输出滤波装置，该装置插入在脉宽调制（PWM）电压源逆变器（VSI）和无源负载或动态电机负载之间。与传统的LC低通滤波器相比，该拓扑结构具有体积小、重量轻、电路动态响应快等优点，且成本较低。给出了电路工作原理、数学分析、分析结果和实验结果。电力电子元件的工作，推动聚丙烯滤波电容器新的高频电流限制，以及推动一种新的低损耗高频罐芯电感器材料新的电流和热约束限制，突出显示。
Modern industry installations using power electronic conversion systems are requiring improvements in the loadside output voltage waveshape to meet demands of various operating load conditions. This paper reveals a novel series resonant sinewave output filter apparatus inserted between a pulse width modulated (PWM) voltage source inverter (VSI) and passive load or dynamic motor load. Compared with conventional LC low pass filters, the topology given gives size, weight, fast circuit dynamic response advantages and is relatively cost effective. A description of circuit operation, mathematical analysis, analytical results and experimental results is given. The power electronic component work done to push the polypropylene filter capacitors to new high frequency current limits, as well as pushing a new low loss high-frequency pot core inductor material to new current and thermal constraint limits, is highlighted.
