Abstract
The pulse-width-modulation is used to create a desired amplitude and frequency voltage waveform to feed the motor in different operating points. There are different modulation methods of how to create the desired waveforms. In this paper, waveforms recorded from two-level voltage-source converters with three different modulation methods are analyzed. The voltage and current waveforms are transformed to the frequency domain and the power distribution in the frequency domain is examined. An algorithm to extract the true applied switching frequency is presented. The analysis is performed using 50 Hz output frequency and the load torque values of 100 %, 75 %, 50 %, 25 % and the no-load condition with all three modulation methods. Finally, the effect of the THD calculation procedure to the THD-value is examined and the THD values are compared to other loss indicators of the motor.
