Embodiment 1
[0042] Embodiment 1: refer to figure 1 , figure 2 , a three-dimensional wireless charging system load positioning and power constant control method, comprising the following steps:
[0043]Step 1: Establish the magnetic circuit model and circuit model of the three-dimensional wireless power transfer system, and obtain the constraint relationship between mutual inductance, input power, output power and system efficiency through circuit analysis;
[0044] Such as figure 1 is the magnetic circuit model of the three-dimensional wireless power transfer system, in which the three-dimensional wireless power transfer system is composed of three orthogonal coils, and they are located in the xy plane, xz plane and yz plane respectively, and each transmitting coil is coupled with the receiving coil, denoted Mutual inductance values are M 1 , M 2 and M 3 . In addition, since each transmitting coil is orthogonal to each other, the mutual inductance value between any two transmitti...
