Three-phase harmonic reducing diode rectifier

Abstract

Diode rectifiers are essential utility interfaces for several power converter systems and those provide useful characteristics such as cheap, light weight, compact, high efficiency, lower producing EMI noises, robust for fault high current and etc. Only the unwanted feature of the diode rectifiers is greatly distorted input current which may cause harmonic pollution in power systems. The authors propose a 24-pulse three-phase diode rectifier by means of a simple and unique topology. In this paper, the topology and operating principle are shown and the performance and the practicability are validated through experiments.
