1. A device for DC-DC conversion, the device comprising:
a plurality of input ports configured to receive a set of DC voltage inputs, the plurality of input ports comprising at least one differential input port;
a plurality of input semiconductor switches, each input semiconductor switch of the plurality of input semiconductor switches being coupled to a respective input port of the plurality of input ports;
an inductor coupled to each input semiconductor switch of the plurality of input semiconductor switches;
a pair of output semiconductor switches coupled to the inductor;
an output coupled to the inductor via the pair of output semiconductor switches; and
a processor configured to generate input switch control signals for the plurality of input semiconductor switches to sequentially and selectively connect each DC voltage input of the set of DC voltage inputs to the inductor to charge the inductor and to generate an output switch control signal for the pair of output semiconductor switches to connect the inductor to the output to discharge the inductor via the output.
