串联谐振型双有源桥变换器电流峰值优化控制
Optimal control strategy of current peaks for the series resonant-type dual active bridge converters
摘要
Abstract
Aiming at the series resonant-type dual active bridges(DAB)bi-directional DC/DC converter,the paper presents a current peak optimization control scheme based on the variable frequency phase-shift control.The normalized values of peak inductor current and transmitted power in the dual active bridge converter are firstly obtained by using time domain analysis,then the established model was compared with the calculation results of the conventional fundamental analysis method.In addition,the soft switching range is derived and the dead time is analyzed.Finally,the results of the time-domain analysis and the variable-frequency phase-shifting optimization method are verified by simulation.The simulation results show that the proposed optimized control method can effectively reduce the current peaks under different power levels compared with existing fixed-frequency control.关键词
