Abstract
Systems and methods for controlling a dual active bridge converter or other type of DC-DC converter are disclosed herein. An output voltage of the dual active bridge converter is detected. Based at least in part on the output voltage, a first target duty ratio of a primary bridge of the dual active bridge converter and a second target duty ratio of a secondary bridge of the dual active bridge converter are retrieved from a table. Based on the output voltage, a target phase shift between the primary bridge and the secondary bridge is determined. Based on the first target duty ratio, the second target duty ratio, and the target phase shift, a plurality of switch control signals is caused to be provided to respective switches of the primary bridge and the secondary bridge, to switch according to a time-based switching sequence.
