Abstract :
The increase in iron-loss in soft magnetic materials due to the modulation depth in pulse width modulation (PWM) inverters is analyzed. In particular, the specific loss variations with different modulation indexes are measured, both in wound cores realized with high quality grain oriented magnetic material, and in induction motors
