摘要
基于最基本的解决方法,提出了由电感器,电容器和二极管所组成的三相低谐波二极管整流器的拓扑结构。其中的电感器和电容器与三相二极管整流桥一起作用以改善网侧的电流波形。基于这一拓扑结构,本文提出了一种维持电流很小的交/直变流器和一种在风力发电中应用的可四象限运行的频率变化器。
Several topologies of three-phase low harmonic diode rectifiers equipped with inductors, capacitors and diodes, based on an original solution, are presented. Inductors and capacitors are used in conjunction with the three-phase diode rectifier bridge to improve the waveform of the currents drawn from the utility grid. Starting from this configuration, the paper proposes an AC/DC convener with small holding current and a four-quadrant frequency convener with possible applications for wind turhino
