Research on ZVS Half-Bridge DC/DC Transformer

Liu Kun; Fan Caiyun; Han Kun; Xia Kepeng; Qiu Wenlong; Wang Shuaiqing

The DC transformer (DCT) based on half-bridge topology is studied in this paper, analyzes the circuit principle of work, on the basis of this, the characteristics of DCT are studied, zero voltage switching (ZVS) is deducted, and the characteristic of the output voltage and power transmission of DCT are given, as well as the design method and optimization design. Finally, ZVS half-bridge DC transformer with 120W prototype is developed, the converter has been verified by simulation and experiment.
