摘要：
In this paper, a comparison study of eddy current losses in three-phase induction motors fed by voltage source inverter with sinusoidal pulse width modulation (SPWM) and voltage space vector pulse width modulation (SVPWM) is presented. The simulation model of SPWM and SVPWM inverter are respectively established in MATLAB. After analyzing the harmonic spectrums of inverter output voltage, both the analytic method and FEA (finite element analysis) method are adopted to calculate the eddy current losses. The calculation results show that comparing with SPWM, SVPWM control method could decrease harmonic components of output voltage and reduce the iron losses of the motors.
