Harmonics elimination for DC/DC power supply based on piezoelectric filters

This research presents a study, modelling and simulation of the piezoelectric material work as filters (piezoelectric filter) used to eliminate harmonics in power electronic circuits, high order are generating due switching frequencies circuit equipment, detailed is achieved for filter tested full-bridge DC/DC converter with resistive load works dc supply (12 48 volt). As result, uses have great impact on elimination, which leads reduce overall total harmonic distortion increase efficiency, well output voltage from remain constant by varying resistance over wide range. The including has been simulated using PSIM (V9.1) software.
