Claim 19:
20. A method for adaptive control of a dual active bridge converter, comprising:
periodically sensing an output voltage of the dual active bridge converter coupled to a charging port of an electric vehicle;
in response to sensing a change in the output voltage:
computing a voltage transfer ratio based on the output voltage and an input voltage of the dual active bridge converter;
selecting, based on a voltage transfer ratio, an intra-bridge phase shift computation algorithm from among a plurality of stored intra-bridge phase shift computation algorithms; and
computing, based on the selected intra-bridge phase shift computation algorithm, a target intra-bridge phase shift amount between two bridges of the dual active bridge converter;

generating a time-based zero voltage switching sequence based on the target intra-bridge phase shift amount; and
causing a plurality of switch control signals, which are provided to respective switches of the dual active bridge converter, to switch according to the time-based zero voltage switching sequence to compensate for variations in the output voltage.
