Abstract

The paper focuses on the effects of the inverter characteristics on the losses increment traction motors fed by pulse width modulation (PWM) controlled converters. Using the MATLAB soft, the AC-DC-AC equivalent model is founded on the principle of sinusoidal pulse width modulation (SPWM). The harmonic spectrum of steady-state operation is simulated using this model. In particular, the influence of the following inverter parameters is considered: modulation index, rise time of pulse and switch frequency. The curve of harmonic loss factor (HLF) with a variation of these parameters is given. The simulation results can be used for purposes, such as loss-optimized design of converter machine system, and cooling system design.
