Abstract :
In this paper, a novel transformer for 36-pulse AC-DC conversion is designed, modeled and developed to feed isolated varying DC loads. The proposed transformer is normally used for large current rating rectifiers such as electric-aircraft power supply, electrowinning, electrochemical processes, induction heating, drives, plasma torches, etc., where isolation is required mainly for stepping down the supply voltage. It consists of two paralleled 18-pulse AC-DC converters involving nine-phase shifted diode bridges. It improves power quality at AC mains and it meets IEEE-519 standard requirements at varying loads.
