Interdependence between the harmonics of the output and input currents to a three phase rectifier bridge

Abstract

A large number of scientific papers published recently have as their study object the emergence of voltage and current harmonics and their limitation through various methods or devices. At modern power stations equipped with static converters, the existence of these harmonics is inevitable, because these types of high power electronic assemblies are known as deforming elements. The present article is proposing to show the way how the deforming regime, which affects the current at the output of a three-phased bridge rectifier, influences the current, absorbed by the rectifier from the supply, inducting an nonsinusoidal regime in the connection point of the supply.
