A Novel Model for Predicting Iron Losses of Electrical Steels Fed by PWM Inverter

Abstract:

Based on the Bessel function, a novel calculation model of iron losses of electric magnetic material fed by PWM inverter is proposed. Considering the influence of modulation index of inverters, the numerical relationship between material iron losses and PWM modulation index is presented. By improving on the Epstein frame measuring system, a method is proposed to measure the material loss under non-sinusoidal voltage, two three-phase experimental induction motors fed by inverter is considered, the results prove the model is valid.
