1. A method for controlling a dual active bridge converter, comprising:
detecting an output voltage of the dual active bridge converter;
retrieving, from a predetermined lookup table stored in memory prior to detecting 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 associated with the output voltage;
determining a target phase shift between the primary bridge and the secondary bridge, based on the output voltage; and
causing a plurality of switch control signals, which are provided to respective switches of the primary bridge and the secondary bridge, to switch according to a time-based switching sequence based on the first target duty ratio, the second target duty ratio, and the target phase shift.
