Abstract
Systems and methods for controlling a dual active bridge converter are disclosed herein. A probability of losing zero voltage switching (ZVS) of a dual active bridge (DAB) converter comprising is determined. At least one control variable of a plurality of control variables of the DAB converter is modified to change ZVS margin to achieve ZVS based on a determined probability of losing ZVS. A plurality of switch control signals, which are provided to respective switches of the primary bridge and the secondary bridge of the DAB, are caused to switch according to a time-based switching sequence based on the plurality of control variables.
