Resumé

An optimized switching control strategy to reduce the conduction and switching losses of the dual active bridge converter is presented in this paper. The control strategy can simultaneously reduce the root mean square value and average absolute value of the leakage inductor current, which are closely relevant to the conduction and switching losses of the semiconductor devices and high-frequency transformers. The optimization is conducted by regulating two manipulated variables on the basis of achieving zero-voltage switching for all switches in a wide voltage range as well as effectively reducing the power losses. An experimental prototype was implemented to validate the theoretical analysis and the feasibility of the proposed method. The experimental results revealed that the converter power losses can effectively be reduced and the overall system efficiency can be improved using the proposed control strategy.
