Comparison of low power dc to dc converter topologies

Abstract

High frequency power conversion is attractive for the opportunities newlineit promotes for improved performance DCDC converters operating at high newlinefrequencies use smaller valued energy storage elements which tend to be newlinephysically smaller and lowercost and this can result in improved transient newlineperformance higher power density and retaining high efficiency newlineA major barrier to increase frequency is that some important losses newlineare frequencydependent and become prohibitively large at high frequencies newlineSoftswitching techniques are developed to reduce switching losses newlineThe aim of this work is to investigate different simulation models newlineof DCDC converters based on softswitching and to compare them with newlinehardware measurements newline newline
