Abstract
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 the second end of the transmission line. A second switch is electrically connected between the second end of the transmission line and the load and both switches are movable between an open and a closed position. A switch control circuit switches the first and second electric switches between their open and closed positions at a selected high frequency. A plurality of variable impedance elements are electrically connected to the transmission line at spaced intervals while an impedance control circuit is electrically connected to the variable impedance elements to vary the impedance of the impedance elements and thereby vary the voltage applied to the load.
