초록
In this paper, the bidirectional DC-DC converter is composed of the 900V Silicon-Carbide(SiC) devices to get high efficiency. The 900V SiC device is better than a similar current rated traditional SiC device. it has a lower drain-source resistance and output capacitance. therefore it can reduce the switching and the conduction losses of the DC-DC converter. The experimental results verify the improvement of efficiency and usefulness of 900V SiC device.
