Abstract
A method and an electrical circuit for DC-DC voltage conversion in a network comprising an input voltage terminal, an output voltage terminal, at least one first switch and at least one second switch, at least one input impedance, at least one load impedance and at least one transmission line with known impedance where the electrical circuit is characterized by that the impedance of the at least one transmission line is adapted to be mismatched to at least the load impedance and where at least one of the at least first switches is arranged in relation to the at least one transmission line to switch between open and closed positions for generating a pulse wave propagating in the at least one transmission line charging a load capacitance of the load impedance with electrical energy.
