Analysis Of Hysteresis Losses In Iron Sheets Under Arbitrary Voltage Waveforms

Abstract

This paper analyses and compares experimentally the magnetic hysteresis losses evolution in iron steel sheets submitted to different supplies: sinusoidal, square, triangular, two and three-level PWM voltage waveforms. The magnetic induction amplitude influence and the modulation index are investigated for Two and Three-level PWM voltage waveforms. The experimental investigation is performed using a workbench with a closed loop PWM inverter for imposing the induced voltage waveform on the secondary winding of an Epstein frame.
