Abstract

Size reduction of passive components in power converters especially magnetic components is essential to reduce the overall size of the converter and achieve higher power densities. For that purpose, this paper presents a detailed design procedure of a 4th order resonance output filter to show the advantages it provides in terms of passives size and loss reduction. A design study comparison is presented between 2nd order, 4th order and 4th order resonance filters in a 5.4 W, 20 MHz buck converter with PCB integrated solenoid inductors. The comparison considers the same circuit specifications and PCB manufacturing capabilities for the PCBinductors. It is found that there is potential for a total inductor size reduction of 38% with a corresponding increase in full load inductor efficiency of 2.1% and full load circuit efficiency of 1.3% provided by the 4th order resonance filter compared to a standard 2nd order filter in a 5.4 W buck converter switching at 20 MHz.
