1. A system comprising:
a DC voltage source having a first output and a second output; and
a DC-DC converter having an output, the DC-DC converter comprising:
a first inductor having a first side and a second side, the first side of the first inductor being in electrical communication with the first output of the DC voltage source;
a second inductor having a first side and a second side, the first side of the second inductor being in electrical communication with the first output of the DC voltage source, the first inductor being inversely coupled to the second inductor;
a first switch in communication with the second side of the first inductor and the second output of the DC voltage source;
a second switch in communication with the second side of the second inductor and the second output of the DC voltage source; and
a first capacitor connected between the second output of the DC voltage source and the second side of the first inductor.
