Abstract

In this paper, a transformer configuration for 44-pulse AC-DC converter configuration is designed, modeled and simulated to feed isolated DC varying loads. The proposed transformer is suitable for large current rating rectifiers such as electric-aircraft power supply, electrowinning, electrochemical processes, plasma torches, etc., where isolation is required mainly for stepping down the supply voltage. It consists of two paralleled 22-pulse AC-DC converters involving eleven-phase shifted uncontrolled diode bridges. It improves power quality at AC mains and it meets the most stringent power quality requirements at varying loads.
