The universal power electronics based distribution transformer, an unified approach

Abstract

A high frequency switched, power electronics based distribution transformer is introduced and described. Besides the definition of appropriate voltage- and power ratings also several preferred topologies are discussed, favorable to replace the typical power frequency distribution transformer by a high frequency switched one with low number of variants. Special attention is paid on modularity and on automated production capability of all individual components, very low first and operating costs e.g. low maintenance costs, long operation Intervals and high efficiency especially at partial load.
