Rectifier transformer

Overview

DC power supply is widely applied in metallurgy, electrochemistry and transmission industries and in industrial field, most of the DC power supplies are abtained by transforming AC power supply to the required DC power supply through rectifier transformer and rectifier elements. There are two funcions of rectifier transformer: one is to change voltage and the other is to change the number of phase. Multi-pulse waves can be formed through phase shifting, so as to improve power quality and prevent power grid from being polluted by harmonic wave.
