Abstract :
This paper discusses for a bi-directional isolated DC/DC converter using series voltage compensation. The proposed converter consists of a high efficiency resonance full-bridge converter and a series converter. The proposed circuit regulates the output voltage by using the series converter, which provides only the differential voltage between the input voltage and the output voltage that is closed to the nominal voltage, since only the resonance converter will operate. In this paper, four types of the auxiliary circuits are investigated using the loss calculation. The relationship between the loss element and efficiency characteristics is clarified. The validity of the proposed circuit was confirmed by experimental results, which converts 48-V to 380-V at 1kW, with a maximum efficiency of 95% at 1 kW at the nominal input voltage region.
