DYNAMIC RESONANCE MATCHING CIRCUIT FOR WIRELESS ENERGY RECEIVERS Russian patent published in 2016 - IPC H04B5/00 

FIELD: radio engineering and communications.

SUBSTANCE: invention relates to communication equipment and can be used in wireless communication systems. For this purpose, resonance matching circuit (310) for matching wireless energy transmission system resonance frequency with frequency of power signal comprises switch (311), connected in parallel with resonant element (302) of wireless energy transmission system; and controller (312), connected to switch (311) and configured to detect crossing zero voltage level signal, passing through resonant element (302), and closing switch (311) during predetermined period of time in case of crossing zero voltage level, wherein circuit switch (311) during predetermined period of time adds any one of inductive and capacitance value to resonance frequency of wireless energy transmission system.

EFFECT: high reliability of communication.
