In this paper, a new three-phase input, three-phase Transformer (PET), regulated sinusoidal AC power supplies four-wire output, and with a high-frequency AC link matrix and AC regulators. type convertor is discussed. The topology of the conventionalRecently, a few three-phase PETs have been reported [3, matrix convertor is modified with an additional high-frequency 4], but they need whether too many AC/DC links, large transformer for three-phase four-wire electronic power distribulky magnetic components or dc-link electrolytic capacibution application.
