Abstract :
The main goal of this paper is to analyze and compare the evolution of magnetic hysteresis losses in silicon-steel sheets submitted to three different supplies: sinusoidal and two and three-level PWM voltages. The influence of the magnetic induction amplitude, the triangular frequency and the modulation index are considered. This experimental investigation was performed using a workbench constituted by a PWM inverter, an oscilloscope and computers for signal generation, data acquisition and calculations
