Mitigation of Motor Overvoltage in SiC-Device-Based Drives using a Soft-Switching Inverter [PDF]
, 2020 In SiC motor drives, the high-voltage slew rate (dv/dt) of switching transients results in excessive motor overvoltage, due to the reflected wave phenomenon (RWP), which stands behind the premature failure of motor winding insulation while raises ...
