Abstract

The object of this work is to report a passive filter structure dedicated for power applications. The structure is based on a series combination of elementary notch filters resonating at harmonic frequencies of a base frequency (switching frequency of a converter). A calculation of values of the components used for a given performance is presented. In addition, energy study comparing the behavior of this new structure with that of a traditional LC filter shows that the same performances can be achieved with the 50% volume reduction.
