Patent ID: 8174247

Claim:
An electrical circuit for DC-DC voltage conversion in a network comprising: an input voltage terminal; at least one input impedance (C IN ) coupled in parallel to the input voltage terminal; at least one first switch (T 1 ) coupled in series with the input voltage terminal; and at least one transmission line with known impedance coupled in series with the at least one first switch (T 1 ); at least one second switch (T 2 ) coupled in series with the at least one transmission line; an output voltage terminal in series with the second switch (T 2 ); at least one load impedance coupled to the output voltage terminal; wherein 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 (T 1 ) 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 the load capacitance (C OUT ) of the load impedance with electrical energy.
