Abstract:
Disclosed are a transmitting coil structure and wireless power transmitting terminal using the transmitting coil structure. The transmitting coil has a first winding and a second winding connected in parallel, so that the transmitting coil has a smaller inductance than the conventional transmitting coil in the condition of the same spatial magnetic field. When the receiving terminal is near the transmitting coil, the inductance of the transmitting coil is smaller, and the influence of the receiving terminal to the inductance of the transmitting coil is reduced significantly, and the effect to the impedance matching of the primary side transmitting coil and the resonant capacitor will not be too large, so as to improve the power transmission efficiency of the system.
