非谐振双有源桥变换器变压器稳态直流电流的研究、量化与校正

The efficiency of dual active bridge (DAB) converters can be greatly improved by using gallium nitride (GaN) semiconductors and high-frequency power transformers. However, the variation in the internal resistance of these devices, and possible time mismatches create an unwanted stationary dc current in the power converter transformer. In this article, a mathematical quantification of the steady-st...
