Distributed power supply with power factor correction: A solution to feed all modules in power electronic transformers

摘要

The idea of power electronic transformer (PET), which works with solid-state switches, has been considered noticeably recently. Every power electronic transformer has several parts which each of them needs its own reliable supply voltage. So the appropriate performance of a PET depends on the existence of various proper supply voltages. The distributed power supply (DPS), which can produce several different supply voltages simultaneously with various powers and high reliability, may be the optimum choice available for the supply of different modules of a PET. In this paper the idea of a distributed power supply with proper topology for a PET has been introduced and its performance and effects on the network has been demonstrated by simulation.
