双方向絶縁形DC/DCコンバータの動作電圧と損失解析 Operating Voltage and Loss Analysis of a Bi-Directional Isolated DC/DC Converter
This paper describes a bi-directional isolated dc/dc converter having a high-frequency transformer with a unity turn ratio, where the input and output dc voltages are different from each other. Theoretical analysis reveals that power loss in the dc/dc converter, as well as peak current flowing in the high-frequency transformer and auxiliary inductors, imposes limitations on the maximum transferable power. The 10-kW, 20-kHz dc/dc converter designed and constructed in this paper is operated with one dc voltage fixed to 320V and the other ranging between 180V and 360V without excessively increased power loss. The effect of the so-called "dead time" on the operating performance is also discussed in this paper. Such wide range of dc voltage may bring about a various application fields to the dc/dc converter.
