If the IGBTs are replaced with wide band-gap semiconductors, specifically silicon carbide FETs, frequencies can be pushed much higher, with better efficiency than IGBTs. Filtering is then easier, so motors operate more efficiently, and faster switching enables better control of the motor to help eliminate effects such as torque ripple which produces audible noise and motor wear.
