Embodiment Construction
[0020] The solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.
[0021] The offset-adaptive reconfigurable wireless power transmission system of the present invention, the P coils composed of magnetic flux tubes are symmetrically arranged in the coil ring gap of the double D transmitting coils, and the on-off of the magnetic flux tubes is controlled to control the switching in and out. Coil turns. When the transmitter coil and the receiver coil have position deviation, the logarithm of the P coil and the position of the P coil are controlled to compensate the mutual inductance of the transmitter coil and the receiver coil.
[0022] In order to determine the mutual inductance compensation strategy, the relevant theoretical derivation process is introduced below.
[0023] According to Bio-Savart's law, the magnetic field magnitudes at a point above and a point on the side of the reconfigurable D...
