Abstract :
The basic principles of operation and the dimensioning of ´zero´-ripple filter concepts, as known for DC/DC boost converters, is discussed. Based on this a novel ´zero´-ripple input filter for a three-phase PWM rectifier system is proposed. The differential-mode characteristics of the filter and the influence of the filter on the selection of the unity gain bandwidth of the input current control is analyzed by simulations.
