Embodiment Construction
[0027] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments, which are explanations rather than limitations of the present invention.
[0028] 1) Design the coupling mechanism of the wireless power transfer system with redundant receiving coils, such as figure 1 Shown are the three coils of the WPT system coupling mechanism with redundant receiving coils, from top to bottom, 101 is the transmitting coil, 102 is the first receiving coil and 103 is the second receiving coil. The distance between the first receiving coil and the second receiving coil is 0.5 mm, and the first receiving coil, which is closer to the transmitting coil, is 10 mm. The specific parameters of the transmitting coil and the first receiving coil are shown in Table 1, and the specific parameters of the second receiving coil are shown in Table 2.
