Abstract
The first five-phase induction motor drive systems were proposed in the late 1970s for variable speed drive applications. Since then, considerable research efforts have been devoted to identifying the development of commercially feasible multiphase propulsion systems. Since the three-phase supply is available from the network, it is necessary to remove a static phase conversion system to obtain a multi-phase supply from the existing three-phase supply. Therefore, this paper presents a new transformer connection scheme to convert a three-phase network power supply into a five-phase constant voltage and constant frequency supply. The proposed transformer connection gives a five-phase output and, therefore, can be used in applications that require a five-phase power supply. Currently, the five-phase motor drive is commercially viable. The five-phase transmission system solution can be further explored as an efficient solution for bulk power transmission. The connection scheme is explained using simulation and experimental approach to prove the feasibility. The geometry of the manufactured transformer is explained in this article.
