Abstract

This paper presents the high power density and high efficiency DC-DC converter for 400V-DC power distribution system. The full-bridge converter is used for typical topology. However, there are some problems such as surge voltage occurrence. Here, the miniaturization of isolated DC-DC converter using the LLC resonant converter which can achieve soft-switching operation without auxiliary circuit is considered. The prototype test circuit is evaluated by experimentally. As a result, the high power density of 12.5W/cm3 and high efficiency of over 95% is achieved.
