DC-coupled hybrid energy system and method for converting DC voltages

A method for setting an operating parameter for a DC to DC voltage converter, the method comprising:

• operating a load, using a controller, with the operating parameter at a first value;
• providing, at the controller, a measurement of an actual inductor current at an inductor of the DC to DC voltage converter;
• providing, at the controller, a measurement of an actual load current drawn by a DC load at an output of the DC to DC voltage converter;
• determining, at the controller, a reference value for the inductor current, based on the actual load current combined with an inductor current adjustment value, wherein the inductor current adjustment value is based on a desired output voltage at the DC load,
• comparing the reference value for the inductor current to the actual inductor current, and maintaining the operating parameter at the first value if the reference value is greater than the actual inductor current, and changing the operating parameter to a second value if the reference value is less than the actual inductor current.
