Embodiment Construction

[0021] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0022] Such as figure 1 As shown, an inductive power transmission system with azimuth self-tuning function includes a transmitting circuit 1, a pick-up circuit 2, a pulse magnetic field generating circuit 3 and an azimuth setting circuit 4. The transmitting circuit 1 is composed of a DC power supply Vcc, a high-frequency inverter The pickup circuit 2 is composed of a pickup coil Ls, a secondary resonance capacitor Cs, a power regulation circuit 7 and a load RL. The exciting coil Lp generates an induced magnetic field B, which generates an induced electromotive force on the pick-up coil Ls, so as to realize the inductive power transmission from the transmitter circuit 1 to the pick-up circuit 2 .

[0023] The pulsed magnetic field generating circuit 3 is provided with a transmitting coil L1, and the transmitting coil L1 is wound on th...

Description

technical field [0001] The invention belongs to the technical field of electromagnetic induction, and specifically relates to an induction power transmission system with azimuth self-adjusting function. Background technique [0002] Energy conduction based on the principle of electromagnetic induction, its transmission efficiency is mainly determined by the effective area of ​​the inductive coupling surface between the pickup coil and the magnetic field (that is, the equivalent vertical plane between the induction coil surface and the magnetic force line), due to the spatial propagation characteristics and strong decay characteristics of the magnetic field , resulting in very strict restrictions on the relative spatial distance and orientation between the induction coil and the magnetic field, especially when there is a large angular deviation between the induction surface of the pickup coil and the normal plane of the magnetic field line, the inductive coupling efficiency wi...
