title = "Modular Multiphase Drives for Variable-Pole Induction Machines in Electric Vehicles",
abstract = "Electric vehicles require high efficiency, compact and reliable high-power drivetrains. A variable-pole induction machine (IM) offers a viable magnet-free solution with distinct advantages, such as extended speed range and better utilization over all loading conditions compared to fixed-pole machines. From a power electronics perspective, a higher number of switching devices is needed to vary the IM pole count. This paper proposes a generalized framework that investigates the efficiency and sizing of a generalized modular multiphase inverter that drives a variable-pole IM. It explores how variable-pole operation benefits and constrains the drive. An experimental GaN-based 18-leg inverter driving a toroidally wound IM is used to validate the theory.",
