Claim 7:
8. A method for controlling a direct current DC-DC converter, the method comprising:
receiving an input voltage Vin to the DC-DC converter;
receiving an output voltage Vo from the DC-DC converter;
generating control signals configured to control a charging output of the DC-DC converter responsive to the received input voltage Vin and the output voltage Vo;
wherein generating the control signals includes receiving from a load device a requested power value chosen from a received requested current value I* and a received requested voltage value V*;
wherein generating the control signals further includes generating an estimated battery current value Iest responsive to the output voltage Vo of the DC-DC converter and the requested current value chosen from the received requested current value I* in a first mode, and the requested current value I* determined from the received requested voltage value V*; and
wherein generating the control signals further includes:
generating a current reference value Iref by combining the requested current value I* with the estimated battery current value Iest; and
generating a control signals phase shift θ* responsive to the received input voltage Vin, the output voltage Vo, and a received requested power value P*;

outputting the generated control signals to the DC-DC converter; and
outputting the charging output from the DC-DC converter to the load device based on the generated control signals.
