This work investigates maximum efficiency control strategies of permanent magnet (PM) traction machine drives that are adopted in General Motors (GM) hybrid and electric vehicles. First, three different current vector control techniques, Maximum Torque Per Ampere (MTPA), Maximum Torque Per Motor Loss (MTPML), and Maximum Torque Per System Loss (MTPSL), are presented to identify the most attractive...
The rapid development of renewable energy systems (RES), especially photovoltaic (PV) energy and wind energy, poses increasing requirements for highpower, low-loss, fast-switching, and reliable semiconductor devices to improve system power capacity, efficiency, power density and reliability. The recent commercialization of wide bandgap (WBG) devices, specifically Silicon Carbide (SiC) and Gallium...
