摘　　要：针对双有源桥(dual active bridges,简称DAB)AC/DC变换器,该文提出基于电流应力优化和6脉波调制的双有源桥AC/DC变换器控制策略.DAB和三相逆变器(three phase inverter,简称TPI)是双有源桥AC/DC变换器的两个关键单元.对DAB采用电流应力优化,对TPI采用6脉波调制.仿真实验结果表明:相对于单移相(single phase shift,简称SPS)调制策略,该文策略的电感电流的峰值更小,即能更有效地降低电流应力.因此,该文所提策略具有优越性.For dual active bridges(DAB)AC/DC converter,a dual active bridge AC/DC.converter control strategy based on current stress optimization and 6-pulse modulation was proposed in this paper.DAB and three phase inverter(TPI)was the two key components of dual active bridge AC/DC converter.DAB was optimized by current stress.TPI was modulated by 6 pulses.Simulation results showed that the peak value of the inductor current of the strategy proposed in this paper was smaller than that of the SPS(single phase shift)modulation strategy,i.e.,the current stress could be reduced more effectively.Therefore,the proposed strategy was superior.
