COIL MODULE, WIRELESS POWER TRANSMITTING CIRCUIT AND WIRELESS POWER RECEIVING CIRCUIT

The present application discloses a coil module, a wireless power transmitting circuit and a wireless power receiving circuit. By overlapping a plurality of coils with each other and arranging matched capacitance between adjacent coils and matched capacitance at the output of the coil module, the coupling inductance is increased, the circulating current caused by parasitic capacitance between overlapped coils is effectively reduced and charging efficiency is improved while the cross-sectional area of the coil is kept constant.
