Finite-Element-Based High-Frequency Modeling of Motor Stator Windings Fed by SiC Inverters for Reflected Voltage Analysis
The emerging adoption of wide-bandgap semiconductor devices in motor-drive systems poses significant challenges to the stator winding dielectric insulation of electrical motors due to their high voltage slew rate. Such ultra-fast switching characteristics generate fast-rising voltage pulses with high $dv/dt$ , which ma...
