Claim 0:
1. A wireless power transmission receiving circuit, comprising:
an electrical energy-receiving oscillation circuit, comprising an electrical energy-receiving coil and a compensation capacitor connected in series, wherein the electrical energy-receiving coil is configured to induct an alternating magnetic field to generate an induction current;
a rectifier circuit, connected to a first and second end of the electrical energy-receiving oscillation circuit to rectify the induction current into a direct current, enabling the direct current to flow to a load;
a modulation circuit, comprising a plurality of modulation sub-circuits, wherein each of the plurality of modulation sub-circuits is respectively connected to the electrical energy-receiving oscillation circuit, the modulation circuit is configured to receive a drive signal to select a modulation sub-circuit corresponding to a power level of the load of the wireless power transmission receiving circuit for operation, and during communication, the modulation sub-circuit is configured to receive a communication signal and load the communication signal on a carrier signal for modulation,
wherein the carrier signal is provided by the electrical energy-receiving oscillation circuit.
