A DC-DC power converter having a power source, a load, and a transmission line terminated at one end. A first switch is electrically connected between the power source and a second end of the transmission line and movable between an open and a closed position. A second switch is electrically connected between the second end of the transmission line and the load and is movable between an open and a closed position. A switch control circuit switches the first and second switches between their respective open and closed positions. A pulse forming network forms the transmission line to store the charge in the transmission line.
