Abstract

For a three-phase three-switch buck-type PWM rectifier with unity power factor, the RMS value of the input filter capacitor voltage ripple is calculated for different modulation methods. A modulation method being optimal concerning the occurring switching losses and the RMS value of the capacitor voltage ripple is identified and guidelines for the dimensioning of the input filter are derived
