Embodiment Construction

[0038] The present invention will be described in detail below in conjunction with accompanying drawing: Figure 1-5 As shown, a parallel communication method for MIMO charging based on magnetic resonance, which includes the first part is the deployment of the transmitter (TX), which mainly includes four parts: TX coil; TX voltage control; TX current measurement; TX controller.

[0039] a.TX coil: We use multiple identical transmitter coils made of printed circuit boards with a radius of 15 cm and an area of ​​0.0707 square meters to ensure the consistency of the transmitter coils.

[0040] b. TX voltage control: TX voltage is driven by the sinusoidal signal generated by the AD9959 high-frequency signal generation chip, and amplified by the ADA4870 amplifier chip. Therefore, AD9959 can adjust the voltage settings of each TX, including amplitude and phase, and we set the frequency of TX voltage conversion as 8KHz.

[0041] c. TX current measurement: We use AD8302 to measure TX...
