1. A DC to DC converter comprising:

  • a full bridge inverter having a positive input, a negative input, a first output, and a second output, said full bridge inverter comprising a first high side switch, a second high side switch, a first low side switch, and a second low side switch, each of said switches having an on state and an off state wherein the switch will conduct current in the on state and will not conduct current in the off state;

    a current doubler connected between the first output and the second output of the full bridge inverter;

    a first current sensor connected between the positive input of the full bridge inverter and the first high side switch of the full bridge inverter, said first current sensor for providing a signal indicative of a current from a power source to the first high side switch; and

    a controller for receiving the signal indicative of the current from the power source to the first high side switch and selectively switching each of the first high side switch, second high side switch, first low side switch, and second low side switch between the on state and the off state as a function of said signal indicative of the current from the power source to the first high side switch.
