Abstract
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 ratio of a primary bridge and a second duty ratio of a secondary bridge are determined, at least one of the first duty ratio and the second duty ratio are 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. A plurality of switch control signals, which are provided to respective switches of the primary bridge and the secondary bridge, are caused to switch according to a time-based switching sequence based on the first duty ratio and the second duty ratio.
