Method and apparatus for controlling a DC/DC power converter

A DC-DC power converter arranged to supply electric power originating from a DC power source to a high-voltage bus, comprising:

• a plurality of interleaved switched inductance circuits, a bulk capacitor, and a HWIO (“hardware input/output”) circuit including a gate driver circuit and an electrical interface circuit;
• wherein each of the interleaved switched inductance circuits includes an inductor, a diode and a power semiconductor switch, and a current sensor;
• wherein the DC-DC power converter is operated at a fixed frequency with a preset cycle time;
• wherein the plurality of switched inductance circuits are operated with offsets in phase during each cycle period;
• and
• a controller, in communication with the HWIO circuit, the controller including a memory device including an instruction set, the instruction set executable to:
• determine a desired control mode for operating the DC-DC power converter, wherein the desired control mode comprises one of a voltage control mode and a current control mode;
• determine a desired voltage for operating the DC-DC power converter based upon the desired control mode;
• determine a desired differential current for operating the DC-DC power converter based upon the desired control mode;
• determine a desired current for operating the DC-DC power converter based upon the desired differential current and the desired voltage;
• and
• control operation of the DC-DC power converter in the desired control mode based upon the desired voltage and the desired current.
