초록
This paper gives and analytical expression of the average and rms currents of switching devices in volt-age-fed PWM inverters. It is shown that the device currents are represented by a function of the power factor of the load and the normalized output voltage of the inverter. The validity of the derived formulas is confirmed with simulation and experiment, showing that the modulation method has a minor effect on the characteristics of the device current.
