This contribution presents a novel approach to reduce electromagnetic interference of switched-mode power supplies. The interference reduction is based on the inverse piezoelectric effect. Providing a low-impedance propagation path for conducted emissions at a resonance frequency of a piezoelectric element, we can attenuate a discrete disturbance peak of a disturbance spectrum. We successfully integrated our novel piezoelectric EMI-filter in a flyback-converter in order to suppress a common-mode disturbance peak. Measurement results reveal that the suppression effect can be improved by 31 dB compared to a similar regular interference-suppression capacitor. Regarding the practical use of the developed piezoelectric EMI-filter, the temperature dependence is examined in addition.
