Comparative Evaluation of Isolated dc-dc Converters for Low Power Applications

Abstract

Isolated dc-dc converters are particularly important for utilizing renewable energy. These converters are used for direct connection to the dc microgrid or as voltage boosters for on/off-grid ac applications. This article examines and evaluates five popular types of isolated dc-dc converters for low-power applications. In this study, by examining the performance of converters, the general equations governing these converters have been extracted. The converter components are then designed for a low-power application. Using simulations in Simulink/MATLAB, these converters have been evaluated and compared from different perspectives
