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...
In recent years, energy consumption has been increasing rapidly due to the increased use of Information and Communication Technology (ICT) systems. As one solution to this issue, 380 V dc power distribution systems have been attracting attention as high-efficiency and high-reliability power systems that can be used in telecommunications buildings and data centers. Against this background, we have...
In an isolated DC-DC converter utilized in the HVDC power distribution system, a large surge voltage occurs across the secondary-side diodes due to the transformer's leakage inductance, and then the diodes with a large withstand voltage are required. However, those diodes cause a lot of power loss. In this paper, a simple surge snubber with prominent surge suppression capability is examined, and the...
In recent years, 380V power distribution systems have been attracting attention as high-efficiency and high-reliability power systems that can be used in telecommunications buildings and data centers. The move toward the proactive use of natural energy, meanwhile, has also been gaining strength. Against this background, we have been moving forward on the construction and experimental study of a container...
