Magnetic Resonance Coupling Wireless Charging Device Based On Differential Structure

A magnetic resonance coupling (MRC) wireless charging device based on a differential structure is provided. The device includes a magnetic resonance transmitter module and a magnetic resonance receiver module communicatively connected to the magnetic resonance transmitter module, where the magnetic resonance transmitter module includes a differential amplifier circuit, a plurality of transmitter-side differential filter circuits, a transmitter-side differential matching circuit and a transmitter coil that are sequentially and communicatively connected; the magnetic resonance receiver module includes a receiver coil, a receiver-side differential matching circuit, a plurality of receiver-side differential filter circuits and a current-doubler rectifier circuit that are sequentially and communicatively connected; and the transmitter coil is communicatively connected to the receiver coil. The MRC wireless charging system based on a differential structure can effectively reduce the overall electromagnetic interference and has a low working voltage and low requirements on withstanding voltages and powers of the devices.
