| Abstract(in English) | Recently the scale of a data center is expanding with increase in the amount of communication traffic, and then its power consumption has increased rapidly High-voltage DC power distribution systems(HVDC-PDS) have been developed in order to achieve energy saving of the power supply system in the data center. This HVDC-PDS requires an isolated DC-DC converter with high efficiency and high power density. So far, a full-bridge DC-DC converter has been researched for the aforementioned converter, but some difficulties of surge occurrence and transformer heating prevented the research. This paper proposes a scheme of fabricating LCC current-mode resonant converters as the high-efficiency, high-power-density converter mentioned above. In the experiment of 400V class LLC resonant converters, our target is a high efficiency of more than 95% and a high power-density of 10 to 20W/cm3 at power capacity of several kW. |
