Classification: CPC H  B  Y | IPC H

Claim 0:
1. A controller module for a direct current DC-DC converter, the controller module comprising:
a controller; and
non-transitory computer-readable media configured to store computer-executable instructions configured to cause the controller to:
receive an input voltage Vin to the DC-DC converter;
receive an output voltage Vo from the DC-DC converter;
generate an estimated battery current value Iest responsive to the output voltage Vo and a requested current value I*, wherein in a first mode, the requested current value I* is received by the controller, and in a second mode, the requested current value I* is determined from a received requested voltage value V*;
generate a current reference value Iref by combining the requested current value I* with the estimated battery current value Iest;
generate a control signals phase shift θ* responsive to the received input voltage Vin, the output voltage Vo, and a received requested power value P*;
generate control signals configured to control a charging output of the DC-DC converter responsive to the received input voltage Vin, the output voltage Vo, the estimated battery current value Iest, the current reference value Iref and the control signals phase shift θ*; and
output the generated control signals to the DC-DC converter.
