The multimotor drives supplied from reduced switch-count converter topologies are potentially employed in different applications such as EVs/HEVs and traction systems. Much research work has been done to investigate the feasibility of different series/parallel-motor connections in an appropriate manner while being supplied by a single Voltage Source Inverter (VSI). In this paper, a new Fifteen-Switch Inverter (15-SI) topology for supplying two independent five-phase motors is proposed. This topology can be considered as an extension to the well-known nine-switch converter topology, which can be used to independently control two three-phase motor drives. First, the proposed inverter topology and its mathematical model are presented. Then, three carrier-based Pulse Width Modulation (PWM) schemes to control the converter and their operational constraints are investigated under Common Frequency (CF) and …
