Silicon Carbide Modules Unlock Higher Power Density in Motor Drives

Matthew Feurtado, Application and Systems Engineer; Daniel Martin, Senior Manager Application and System Engineering; Ty McNutt, Director, Power Modules Product Marketing, Wolfspeed

The traction drive is where nearly all of an electric vehicle’s (EV’s) energy is put to use. The drive system must, therefore, perform with the highest possible efficiency while occupying the smallest possible space with the lowest weight — all to maximize the EV range. With the use of dual drives to enhance tr
