Design Notes
IGBT losses depend on operating mode. For motor drives with sinusoidal PWM, use the sinusoidal total (89.1 W). Energy per switching cycle: 8.00 mJ.
IGBT Loss Theory
IGBTs have a constant voltage drop (Vce(on)) unlike MOSFETs, making them preferred for high-voltage, high-current applications. Switching losses are characterized by Eon and Eoff values from the datasheet.
Ptotal = Vce(on) x Ic x D + (Eon + Eoff) x fsw
