Design Of Minimum Volume Emc Input Filters For An Ultra Compact Three-phase Pwm Rectifier

A design procedure is proposed for the EMC filters to be included in a three-phase/-level PWM rectifier unit in order to fulfill EMC requirements related to conducted emissions. An analytical volumetric optimization is performed considering constraints given by electrical safety, power factor and damping of resonances. The procedure avoids the necessity of applying numerical optimization allowing the analytical calculation of the total filter volume as function of rated power and switching frequency. A discussion about the limits of power density for the rectifier employing modern power semiconductors is done and optimum switching frequency of 540 kHz is calculated for a forced air-cooled system. The experimental verification of the proposed procedure is presented through CE measurements in the designed system.
