Aiming at macro three-phase uncontrolled rectifier bridges, a novel three-phase DC side series active power filter (APF) based on one cycle control is proposed. 针对大量使用的三相不可控整流桥,提出了一种新型的基于单周控制的三相直流侧串联型有源电力滤波器,该滤波器串联在整流桥和谐波源负载之间,只...
In order to consume electrical energy, the DC voltage intermediate circuit (2) is connected to a three-phase voltage system via uncontrolled half-wave rectifier valves (3) which, in this case, for example form a six-pulse bridge circuit. Connected opposingly in parallel to each uncontrolled ...
A practical method is proposed for calculating the harmonic currents of a three-phase bridge uncontrolled rectifier with a DC filter, taking into account the AC source reactance. The method is based on the frequency-domain method and the rectifier switching functions. Analytical equations for the ha...
