Abstract

The rapid shift toward electrification in various industries necessitates significant advancements in the power density, reliability, and fault tolerance of electric drive systems. This research investigates inverter topologies for driving higher power density in electric motors, particularly slotless permanent magnet synchronous machines (PMSMs), which eliminate iron stator teeth to reduce weight. However, the reduced inductance in these machines introduces challenges for the inverters that drive them. These low inductance machines have rekindled interest in Current Source Inverters (CSIs), which are well-suited for driving such systems due to their inherent ability to maintain a constant input current. This study evaluates different inverter topologies with an emphasis on minimizing total harmonic distortion (THD) in their current waveforms, as well as their related power density and fault tolerance. Challenges associated with implementing a CSI are addressed, and a CSI is designed and tested to use as a benchmark for various inverter topologies.
