Systems and methods for controlling a dual active bridge converter are disclosed herein. A bus voltage of a dual active bridge (DAB) converter is detected, and a first duty cycle of a primary bridge and a second duty cycle of a secondary bridge are determined. At least one of the first duty cycle and the second duty cycle is modified by adjusting at least one of a differential mode (DM) adjustment variable and a common mode (CM) adjustment variable based on the detected bus voltage. Such that a plurality of switching control signals provided to respective switches of the primary bridge and the secondary bridge are switched according to a time-based switching sequence based on the first duty cycle and the second duty cycle.

    本文公开了用于控制双有源桥转换器的系统和方法。检测双有源桥(DAB)转换器的总线电压,并且确定初级桥的第一占空比和次级桥的第二占空比。通过基于该检测到的总线电压调整差模(DM)调整变量和共模(CM)调整变量中的至少一者来修改该第一占空比和该第二占空比中的至少一者。使得被提供给该初级桥和该次级桥的相应开关的多个开关控制信号基于该第一占空比和该第二占空比根据基于时间的开关序列进行切换。
