Abstract

Abstract—Multiphase electric drives are required in several applications to provide high levels of reliability. A newly developed multiphase Simplified Split-Source Inverter (S3I) provides a boost capability during sags in the input voltage. It also has a wider modulation range and a lower harmonic content than Z-Source Inverters. This paper proposes an Indirect Field-oriented Control (IFOC) strategy for a five-phase induction motor supplied by an S3I. This control strategy can be divided into three parts. The first uses a dual control loop to control the dc-boosted voltage of the S3I and regulate the input current. The second uses a conventional IFOC to control the motor speed and generate sinusoidal voltage references. With a newly developed space vector modulation approach, the third part will generate the switching pulses of the inverter switches. A series of simulations using PLECS and Python were conducted to verify the concept and illustrate the potential of the proposed drive system.
