Description
技术领域technical field

背景技术Background technique
无线电能传输技术已经广泛用于工业生产、消费电子领域中。从小功率的手机无线充电到大功率的电动汽车无线充电，从水下AUV的无线供电到空间设备的非接触供电，无线电能传输技术以其突出的灵活性、安全性和高效性获得越来越多的应用。在无线电能传输过程中，副边需要实时向原边反馈信号，原边也要不断向副边传递信息，而这一信息的传递过程也要采用无线传输。传统的方式是采用无线通信模块(如ZigBee、蓝牙、WiFi等)，通过外接天线实现信息的无线收发，这类通信方式采用电磁波传输信号，而在实际应用中，能量发射端往往需要安装在地下、水下等环境中，此时电磁波的路径损耗增加、信道状态动态变化，传统的无线通信方式已经不再可靠。Wireless power transmission technology has been widely used in the fields of industrial production and consumer electronics. From the wireless charging of small-power mobile phones to the wireless charging of high-power electric vehicles, from the wireless power supply of underwater AUVs to the contactless power supply of space equipment, wireless power transmission technology has gained more and more attention due to its outstanding flexibility, safety and efficiency. Many applications. In the process of wireless power transmission, the secondary side needs to feed back signals to the primary side in real time, and the primary side must also continuously transmit information to the secondary side, and this information transmission process also uses wireless transmission. The traditional method is to use a wireless communication module (such as ZigBee, Bluetooth, WiFi, etc.) to realize wireless transmission and reception of information through an external antenna. This type of communication uses electromagnetic waves to transmit signals. In practical applications, the energy transmitter often needs to be installed underground. , Underwater and other environments, at this time, the path loss of electromagnetic waves increases and the channel state changes dynamically. Traditional wireless communication methods are no longer reliable.
现有技术方案：为了实现能量和信号的同步传输，克服传统电磁波无线通信的局限性，现有的技术方案是对传输能量进行幅度调制，通过磁场传输信号。这种方式能够解决水下等介质中无法通信的问题，但是其传输能量受幅度调制的影响，不能获得稳定的功率输出。Existing technical solution: In order to realize the synchronous transmission of energy and signal and overcome the limitations of traditional electromagnetic wave wireless communication, the existing technical solution is to perform amplitude modulation on the transmitted energy and transmit the signal through the magnetic field. This method can solve the problem of inability to communicate in underwater and other media, but its transmission energy is affected by amplitude modulation, and stable power output cannot be obtained.

交流功率源发出频率为f1的交流电压，引起原边谐振匹配电路谐振，产生谐振电流I 1，该谐振电流激发频率为f1的交变磁场；副边谐振匹配电路中的线圈通过谐振耦合接收到该交变磁场，并产生谐振电流I2给负载供电。由于电感L6和电容C6组成的LC并联谐振、电感L4和电容C4组成的LC并联谐振、电感L12和电容C12组成的LC并联谐振、电感L14和电容C14组成的LC并联谐振的谐振频率为f1，因此当频率为f1时它们的阻抗达到最大值，减少能量传输对信号传输的影响。The AC power source sends out an AC voltage with a frequency of f1, which causes the resonance of the primary side resonant matching circuit to generate a resonant current I 1, which excites an alternating magnetic field with a frequency of f1; the coil in the secondary side resonant matching circuit receives it through resonant coupling The alternating magnetic field generates a resonant current I2 to supply power to the load. Since the LC parallel resonance composed of the inductor L6 and the capacitor C6, the LC parallel resonance composed of the inductor L4 and the capacitor C4, the LC parallel resonance composed of the inductor L12 and the capacitor C12, and the LC parallel resonance composed of the inductor L14 and the capacitor C14 have a resonant frequency of f1, Therefore, when the frequency is f1, their impedance reaches the maximum value, reducing the influence of energy transmission on signal transmission.
信号源1产生频率为f2的交流电压信号，引起原边谐振匹配电路谐振，产生谐振电流I3，该谐振电流激发频率为f2的交变磁场；副边谐振匹配电路中的线圈通过谐振耦合接收到该交变磁场，并在电容C15上产生频率为f2的谐振电压，信号检测电路1检测该谐振电压，即实现了原边到副边的信号传输。Signal source 1 generates an AC voltage signal with a frequency of f2, which causes the resonance of the primary side resonant matching circuit to generate a resonant current I3, which excites an alternating magnetic field with a frequency of f2; the coil in the secondary resonant matching circuit receives the signal through resonant coupling The alternating magnetic field generates a resonant voltage of frequency f2 on the capacitor C15, and the signal detection circuit 1 detects the resonant voltage, which realizes the signal transmission from the primary side to the secondary side.
副边到原边的信号传输过程与原边到副边相同。The signal transmission process from the secondary side to the primary side is the same as that from the primary side to the secondary side.
