Disclosed is a DC-DC converter with a converter bridge, tank circuitry, and rectifier circuitry. In one embodiment, the converter bridge includes multiple switch circuits, which are formed with silicon carbide MOSFETs (metal on semiconductor field effect transistors), and are configured to provide a primary current. The tank circuitry includes a resonant capacitance, a resonant inductance, and a transformer with a primary, a first secondary, and a second secondary. The tank circuitry is configured to receive the primary current, and the transformer is associated with a magnetizing inductance. The resonant frequency of the tank circuitry is greater than about 225 kilohertz as essentially defined by the magnetizing inductance, the resonant capacitance, and the resonant inductance. The rectifier circuitry is coupled to the first secondary and the second secondary coil, and is adapted to provide a rectified output current.
