Embodiment Construction
[0030] The solutions of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0031] The present invention is a dual-channel wireless power supply system constant current output method based on composite coils. Aiming at the coil system integrated with DD coils and flat solenoid coils, the DD coils and flat solenoid coils are respectively used as the coupling in the LCC topology. The coil and the resonant coil, when the transmitting coil and the receiving coil are facing each other, the DD coil and the flat solenoid coil jointly transmit energy to the receiving coil; when the receiving coil is offset in the longitudinal direction, due to the characteristics of the DD coil and the flat helical coil , the magnetic flux received by the receiving coil will hardly change, which ensures the constant current output of the load; when the receiving coil is offset in the lateral direction, the magnetic flux of the ...
