要約(英語): This paper discusses a bidirectional isolated DC/DC converter using the series compensation method. The proposed converter consists of a high efficiency resonance full-bridge converter and a series converter. This proposed circuit regulates the output voltage by the series converter, which provides only the differential voltage between the input voltage and the output voltage, which is close to the nominal voltage.In this study, four types of auxiliary circuits are investigated in terms of loss. The relationship between the loss element and efficiency characteristics is clarified. The validity of the proposed circuit is confirmed by the loss calculation. Moreover, the experimental results confirmed that the proposed circuit, which converts 48V to 380V at 1kW, achieves a maximum efficiency of 95.5% at the nominal input voltage region.
