摘要

讨论了两种电流源:高频谐振软开关、基于逆变器的有源滤波器。高开关速度导致注入电流的快速瞬态响应。谐波和随机噪声的补偿是可能的。提出了一种新的矢量计算器，它提供了支持三相负载实际功率要求所需的“平衡”基波实际负载电流的瞬时值。注入电流参考由实际电流与实际负载电流之差导出。基本无功补偿或功率因数补偿可同时进行

Fast compensation by a pulsed resonant current source active power filter

Two current source, high frequency resonant soft switched, inverter based, active power filters (APF) are discussed. High switching speeds lead to a fast transient response of injected current. Compensation of harmonics and random noise is possible. A new vector calculator is presented which provides an instantaneous value of the 'balanced' fundamental real load current needed to support the real power requirements of the three-phase load. The injected current reference is derived from the difference between the real current and the actual load current. Fundamental VAr or power factor compensation can be carried out at the same time.<>
