The invention relates to a magnetic resonance wireless charging reception plate high energy resonance circuit module (1), comprising an upper layer (2) and a lower layer. The magnetic resonance wireless charging reception plate high energy resonance circuit module is characterized in that: the reception plate module (1) adopts an upper layer (2) resonance circuit inductance coil, the thickness of which is no more than 2 centimeters and the lower layer (3) thickness is no more than 3 centimeters; a fixed value capacitor and a parallel connection variable capacitor (C2) of a semicircle double-moving-plate assembly (5,6) for tuning are positioned; the variable capacitor drives double gears (12) to follow up the double semicircular moving plates; the regulation mode can be hand-operated (18) and automatic (8,17); and the fixed value capacitor portion (4,C1) is integratedly constructed according to the charge medium plane concept. The resonant frequency regulation mechanism of the invention can adapt to the high voltage strong power oscillation circuit.
Description
technical field [0001] The invention relates to a magnetic resonance tuning circuit construction component of a wireless power receiving system and the tuning of a resonance frequency point of a large-energy LC resonance circuit, and belongs to the technical field of wireless power transmission. Background technique [0002] Radio signal reception depends on the frequency tuning of the resonant circuit, and magnetic resonance wireless power reception also relies on the tuning of the resonant frequency. Only when the resonant frequency points of the sending and receiving are the same can the power receiving effect with high efficiency be produced. Before the present invention appeared, the capacitor and inductance components in the resonant circuit of the kilowatt power level did not break through the high voltage and high current limit, especially the resonant frequency tuning problem, which always made the high power level wireless power transmission flawed.
