novel variable-frequency three-phase induction motor drive system using only three controlled switches
FREE-DOWNLOAD BA Welchko… – Industry Applications, research Abstract—This paper presents a novel variable-frequency motor drive system for a three-phase induction machine. In this drive system, the machine is excited by unidirectional stator currents shaped and sequenced such that a rotating air-gap flux is induced so that the machine
