随着电子设备的尺寸越来越大，其待机时长也越来越短，因此电子设备充电效率也受到用户的关注。以无线充电为例，不同厂商提供的无线充电设备所使用的充电协议不同，使得无线充电设备的工作频率不同，进而导致电子设备仅能使用与之匹配的无线充电设备进行充电，或者说现有电子设备内无线接收电路与无线充电设备的兼容性较差，降低使用体验。As the size of electronic devices becomes larger and larger, their standby time becomes shorter and shorter, so the charging efficiency of electronic devices also attracts the attention of users. Take wireless charging as an example. Wireless charging devices provided by different manufacturers use different charging protocols, which results in different working frequencies of wireless charging devices. As a result, electronic devices can only be charged using matching wireless charging devices. In other words, existing The wireless receiving circuit in the electronic device has poor compatibility with the wireless charging device, which reduces the user experience.

At this time, the wireless receiving circuit is equivalent to the first power filter circuit, and the operating frequency of the first power filter circuit is located between the first cutoff frequency and the center operating frequency; when the operating frequency of the input source is greater than the center operating frequency of the wireless receiving circuit, the wireless receiving circuit can change the frequency Electromagnetic signals greater than the second cutoff frequency are filtered out, and the wireless receiving circuit is equivalent to a second power filter circuit, and the operating frequency of the second power filter circuit is located between the second cutoff frequency and the center operating frequency.

或者，当无线接收电路采用电场耦合式传输电能时，如图2所示，第一数量个串联谐振单元11串联在输入源(此时为一个电流源，I _S)和负载R之间，无线接收电路中指定并联谐振单元中电容器件C ₁作为接收器件；每个串联谐振单元靠近输入源一端和地之间串接一个并联谐振单元12；无线接收电路用于耦合第一截止频率和第二截止频率内的电磁信号，并输出与输入电流的增益位于设定增益范围之内的输出电流。 Or, when the wireless receiving circuit uses electric field coupling to transmit electric energy, as shown in Figure 2, the first number of series resonance units 11 are connected in series between the input source (in this case, a current source, _IS ) and the load R, and the wireless The capacitor C ₁ in the parallel resonant unit is designated as the receiving device in the receiving circuit; a parallel resonant unit 12 is connected in series between one end of each series resonant unit close to the input source and the ground; the wireless receiving circuit is used to couple the first cutoff frequency and the second It cuts off the electromagnetic signal within the frequency and outputs an output current whose gain is within the set gain range compared with the input current.

本实施例中，串联谐振单元的第一数量可以等于并联谐振单元的第二数量，此时无线接收电路如图2或者图3所示。In this embodiment, the first number of series resonant units may be equal to the second number of parallel resonant units. In this case, the wireless receiving circuit is as shown in Figure 2 or Figure 3.

或者，串联谐振单元的第一数量可以比并联谐振单元的第二数量大1，此时无线接收电路如图1所示。技术人员可以根据具体场景合理选择串联谐振单元和并联谐振单元的数量，在无线接收电路增益的平缓程度满足要求即增益位于设定增益范围之内时，相应方案落入本公开的保护范围。Alternatively, the first number of series resonant units may be greater than the second number of parallel resonant units by one, in which case the wireless receiving circuit is as shown in Figure 1 . Technicians can reasonably select the number of series resonant units and parallel resonant units according to specific scenarios. When the smoothness of the gain of the wireless receiving circuit meets the requirements, that is, the gain is within the set gain range, the corresponding solution falls within the protection scope of the present disclosure.

考虑到无线接收电路采用电场耦合式传输电能的电路结构是采用磁场耦合式传输电能的电路结构的对偶变换，因此后续各实施例中仅以图2所示的磁场耦合式传输电能的电路结构来描述无线接收电路的配置方法。Considering that the circuit structure of the wireless receiving circuit using electric field coupling to transmit electric energy is the dual transformation of the circuit structure using magnetic field coupling to transmit electric energy, the subsequent embodiments only use the circuit structure of magnetic field coupling to transmit electric energy as shown in Figure 2. Describes how to configure a wireless receiving circuit.

继续参见图1，串联谐振单元包括串联的电容器件和电感器件。以串联谐振单元11为例，串联谐振单元11包括电感器件L ₁和电容器件C ₁，电感器件L ₁和电容器件C ₁串联；以串联谐振单元13为例，串联谐振单元13包括电感器件L ₃和电容器件C ₃，电感器件L ₃和电容器件C ₃串联。以并联谐振单元12为例，并联谐振单元12包括电感器件L ₂和电容器件C ₂，并且电感器件L ₂和电容器件C ₂并联。 Continuing to refer to Figure 1, the series resonance unit includes a capacitive device and an inductive device connected in series. Taking the series resonance unit 11 as an example, the series resonance unit 11 includes an inductance device L ₁ and a capacitance device C ₁ , and the inductance device L ₁ and the capacitance device C ₁ are connected in series; taking the series resonance unit 13 as an example, the series resonance unit 13 includes an inductance device L ₃ and the capacitive device C ₃ are connected in series, and the inductive device L ₃ and the capacitive device C ₃ are connected in series. Taking the parallel resonance unit 12 as an example, the parallel resonance unit 12 includes an inductance device L ₂ and a capacitance device C ₂ , and the inductance device L ₂ and the capacitance device C ₂ are connected in parallel.

可理解的是，在确定图1所示的无线接收电路之后即确定了无线接收电路的电路结构，然后，继续获取图1所示的无线接收电路中电感器件L ₁～L ₃和电容器件C ₁～C ₃的参数值。参见图4，无线接收电路中各个器件的参数值通过以下步骤获取，包括步骤41～步骤45。 It can be understood that after determining the wireless receiving circuit shown in Figure 1, the circuit structure of the wireless receiving circuit is determined, and then continue to obtain the inductive devices L ₁ to L ₃ and the capacitive device C in the wireless receiving circuit shown in Figure 1 ₁ to C ₃ parameter values. Referring to Figure 4, the parameter values of each device in the wireless receiving circuit are obtained through the following steps, including steps 41 to 45.

在步骤41中，获取所述无线接收电路对应的目标等效电路；所述无线接收电路的工作频率位于第一截止频率和第二截止频率之间。In step 41, the target equivalent circuit corresponding to the wireless receiving circuit is obtained; the operating frequency of the wireless receiving circuit is between the first cutoff frequency and the second cutoff frequency.

本步骤中，在确定图2的无线接收电路的电路结构之后，无线接收电路中各个器件的位置同时确定，此时对图2所示无线接收电路进行处理，例如可以将无线接收电路的各个串联谐振单元内的电容器件等效为短路，如图5中将电容器件C ₁和电容器件C ₃用双向箭头连接起来，或者说直接将电容器件换成导线；以及将无线接收电路的各个并联谐振单元内的电感器件等效为开路，如图5中用X号将电感器件L ₂断开，或者说直接去掉电感器件L ₂，得到图6所示的目标等效电路。 In this step, after the circuit structure of the wireless receiving circuit in Figure 2 is determined, the positions of each component in the wireless receiving circuit are determined at the same time. At this time, the wireless receiving circuit shown in Figure 2 is processed. For example, the various components of the wireless receiving circuit can be connected in series. The capacitive device in the resonant unit is equivalent to a short circuit. In Figure 5, the capacitive device C ₁ and the capacitive device C ₃ are connected with a two-way arrow, or the capacitive device is directly replaced with a wire; and each parallel resonance of the wireless receiving circuit is The inductance device in the unit is equivalent to an open circuit. In Figure 5, use the X number to disconnect the inductance device L ₂ , or directly remove the inductance device L ₂ , and obtain the target equivalent circuit shown in Figure 6.

在步骤42中，确定所述目标等效电路中各个器件的参数值(即第一参数值)；所述参数值与所述第一截止频率和所述第二截止频率相关。In step 42, parameter values (ie, first parameter values) of each device in the target equivalent circuit are determined; the parameter values are related to the first cutoff frequency and the second cutoff frequency.

本步骤中可以获取第一截止频率F _L、第二截止频率F _H和负载的电阻值R。可理解的是，在设计一个无线接收电路时，设计人员通常是已知无线接收电路的工作频率的频率范围的，即第一截止频率F _L和第二截止频率F _H。考虑到无线接收电路最终会应用到电子设备(即在电子设备中将电磁信号以设定增益输出至负载)之中，那么电子设备对应负载(如电池)的电阻值是可以确定的。也就是说，第一截止频率F _L、第二截止频率F _H和负载的电阻值R需要预先设置，并且存储到电子设备与之通信的指定位置，如本地存储器、缓存或者外部存储器等。 In this step, the first cutoff frequency _FL , the second cutoff frequency _FH and the resistance value R of the load can be obtained. It is understandable that when designing a wireless receiving circuit, designers usually know the frequency range of the working frequency of the wireless receiving circuit, that is, the first cutoff frequency _FL and the second cutoff frequency _FH . Considering that the wireless receiving circuit will eventually be applied to electronic equipment (that is, the electromagnetic signal is output to the load at a set gain in the electronic equipment), then the resistance value of the electronic equipment corresponding to the load (such as a battery) can be determined. That is to say, the first cutoff frequency _FL , the second cutoff frequency _FH and the resistance value R of the load need to be set in advance and stored in a designated location with which the electronic device communicates, such as local memory, cache or external memory.

本实施例中可以获取预设的参数计算模型，以目标等效电路为第二功率滤波电路作为示例，目标等效电路的各个器件对应一个参数计算模型，参见式(1)～式(3)：In this embodiment, a preset parameter calculation model can be obtained. Taking the target equivalent circuit as the second power filter circuit as an example, each device of the target equivalent circuit corresponds to a parameter calculation model, see equations (1) to (3) :

式(1)～(3)中，g ₁、g ₂、g ₃是目标等效电路的归一化系数，上述归一化系数的设置原则是让增益曲线在第一截止频率和第二截止频率之间更平缓。在一示例中，上述g ₁、g ₂、g ₃分别取值为1.5、1.33和0.5。该示例中，基于上述公式(1)～(3)，可以确定第二功率滤波电路中电感器件L ₁、电容器件C ₂和电感器件L ₃的参数值(即第一参数值)。 In formulas (1) to (3), g ₁ , g ₂ , and g ₃ are the normalization coefficients of the target equivalent circuit. The setting principle of the above normalization coefficients is to make the gain curve at the first cutoff frequency and the second cutoff frequency. Frequencies are smoother between frequencies. In an example, the values of g ₁ , g ₂ , and g ₃ mentioned above are 1.5, 1.33, and 0.5 respectively. In this example, based on the above formulas (1) to (3), the parameter values (ie, the first parameter values) of the inductor device L ₁ , the capacitor device C ₂ and the inductor device L ₃ in the second power filter circuit can be determined.

本步骤中可以基于上述参数计算模型，根据第一截止频率、第二截止频率和负载的电阻值计算所述目标等效电路中各个器件的第一参数值。即将第一截止频率、第二截止频率和负载的电阻值代入上述参数计算模型后计算出的结果即是相应器件的参数值(即目标等效电路中各个器件的第一参数值)。In this step, the first parameter value of each device in the target equivalent circuit may be calculated based on the first cutoff frequency, the second cutoff frequency and the resistance value of the load based on the above parameter calculation model. That is, after substituting the first cutoff frequency, the second cutoff frequency and the resistance value of the load into the above parameter calculation model, the calculated result is the parameter value of the corresponding device (that is, the first parameter value of each device in the target equivalent circuit).

在步骤43中，获取所述无线接收电路的中心工作频率。In step 43, the center operating frequency of the wireless receiving circuit is obtained.

本步骤中可以根据所述第一截止频率和所述第二截止频率获取所述无线接收电路的中心工作频率。举例来说，可以获取预设的中心频率计算模型，该中心频率计算模型用于计算出位于第一截止频率和第二截止频率之间的频率；然后可以将第一截止频率和第二截止频率输入到中心频率计算模型，从而获得中心频率计算模型输出的中心工作频率。可理解的是，该中心频率计算模型可以根据具体场景选择，在使得中心工作频率位于第一截止频率和第二截止频率之间的情况下，相应方案落入本公开的保护范围。In this step, the center operating frequency of the wireless receiving circuit can be obtained based on the first cutoff frequency and the second cutoff frequency. For example, a preset center frequency calculation model can be obtained, and the center frequency calculation model is used to calculate the frequency between the first cutoff frequency and the second cutoff frequency; and then the first cutoff frequency and the second cutoff frequency can be Input to the center frequency calculation model to obtain the center operating frequency output by the center frequency calculation model. It can be understood that the center frequency calculation model can be selected according to specific scenarios. In the case where the central operating frequency is located between the first cutoff frequency and the second cutoff frequency, the corresponding solution falls within the protection scope of the present disclosure.

在一示例中，上述中心频率计算模型计算中心工作频率的步骤为：计算所述第一截止频率和所述第二截止频率的乘积；然后，获取所述乘积的平方根，将所述平方根作为所述中心工作频率。即上述中心频率计算模型的公式为：In one example, the above-mentioned central frequency calculation model calculates the central operating frequency by: calculating the product of the first cutoff frequency and the second cutoff frequency; then, obtaining the square root of the product, and using the square root as the Describe the center operating frequency. That is, the formula of the above central frequency calculation model is:

式(4)中，F _c表示中心工作频率。 In formula (4), F _c represents the center operating frequency.

需要说明的是，技术人员可以根据具体场景选择合适的中心频率计算模型，以使中心工作频率落入第一截止频率和第二截止频率之间的范围即可；例如，该中心工作频率也可以是第一截止频率和第二截止频率的平均值。可理解的是，本示例中通过上述中心频率计算模型可以建立中心工作频率、第一截止频率和第二截止频率之间的关联关系；换言之，本示例中通过中心工作频率与两个截止频率的关联关系可以使目标等效电路与无线接收电路之间建立关联关系，即建立了目标等效电路与无线接收电路中器件的关联关系。It should be noted that technicians can select an appropriate center frequency calculation model according to specific scenarios, so that the center operating frequency falls within the range between the first cutoff frequency and the second cutoff frequency; for example, the center operating frequency can also be is the average of the first cutoff frequency and the second cutoff frequency. It can be understood that in this example, the correlation between the center operating frequency, the first cutoff frequency and the second cutoff frequency can be established through the above center frequency calculation model; in other words, in this example, through the center operating frequency and the two cutoff frequencies The association relationship can establish an association relationship between the target equivalent circuit and the wireless receiving circuit, that is, the association relationship between the target equivalent circuit and the devices in the wireless receiving circuit is established.

在步骤44中，将所述目标等效电路中各个器件的参数值(即第一参数值)映射到所述无线接收电路之内。In step 44, the parameter values (ie, the first parameter values) of each device in the target equivalent circuit are mapped into the wireless receiving circuit.

考虑到步骤43中已经建立了目标等效电路与无线接收电路中器件的关联关系，因此本步骤中可以将目标等效电路中各个器件的第一参数值映射到无线接收电路之内。或者说，通过将目标等效电路中的参数值映射到无线接收电路，实质上完成了无线接收电路中部分器件的参数值的计算。Considering that the association between the target equivalent circuit and the devices in the wireless receiving circuit has been established in step 43, the first parameter values of each device in the target equivalent circuit can be mapped into the wireless receiving circuit in this step. In other words, by mapping the parameter values in the target equivalent circuit to the wireless receiving circuit, the calculation of the parameter values of some devices in the wireless receiving circuit is essentially completed.

以目标等效电路为第二功率滤波电路作为示例，可以将第二功率滤波电路中电感器件L ₁、电容器件C ₂和电感器件L ₃的参数值(即第一参数值)映射到所述无线接收电路之内。 Taking the target equivalent circuit as the second power filter circuit as an example, the parameter values (that is, the first parameter values) of the inductor device L ₁ , the capacitor device C ₂ and the inductor device L ₃ in the second power filter circuit can be mapped to the within the wireless receiving circuit.

在步骤45中，根据所述中心工作频率获取所述无线接收电路中各个器件的参数值。In step 45, parameter values of each device in the wireless receiving circuit are obtained according to the central operating frequency.

本步骤中可以将无线接收电路中各个串联谐振单元和各个并联谐振单元的谐振频率为所述中心工作频率；然后，根据目标等效电路中各个器件的第一参数值和中心工作频率计算出，和目标等效电路中各个器件在无线接收电路中位于同一个串联谐振单元或者并联谐振单元的其他器件的第二参数值(也即无线接收电路中其他器件的第二参数值)，即计算出步骤41中去掉的器件的参数值。In this step, the resonant frequency of each series resonant unit and each parallel resonant unit in the wireless receiving circuit can be the central operating frequency; then, based on the first parameter value and the central operating frequency of each device in the target equivalent circuit, it is calculated, The second parameter value of other devices located in the same series resonance unit or parallel resonance unit in the wireless receiving circuit as each device in the target equivalent circuit (that is, the second parameter value of other devices in the wireless receiving circuit) is calculated. Parameter values of the device removed in step 41.

继续以图1所示无线接收电路为例，目标等效电路可以为第二功率滤波电路，则步骤45中可以计算出电容器件C ₁和C ₃以及电感器件L ₂的参数值： Continuing to take the wireless receiving circuit shown in Figure 1 as an example, the target equivalent circuit can be the second power filter circuit, then the parameter values of the capacitive devices C ₁ and C ₃ and the inductive device L ₂ can be calculated in step 45:

经过上式(5)～(7)可知，在串联谐振单元11、串联谐振单元13和并联谐振单元12谐振时，在电感器件L ₁和电感器件L ₃，以及电容器件C ₂已知的情况下，可以计算出电容器件C ₁和C ₃以及电感器件L ₂的参数值(即第二参数值)。 It can be seen from the above equations (5) to (7) that when the series resonance unit 11, the series resonance unit 13 and the parallel resonance unit 12 resonate, the inductance device L ₁ , the inductance device L ₃ and the capacitance device C ₂ are known Below, the parameter values (ie, the second parameter value) of the capacitive devices C ₁ and C ₃ and the inductive device L ₂ can be calculated.

然后，本步骤中获取无线接收电路在输出电压VR与次级线圈的开路电压Vsoc 的增益，效果如图7所示；以及无线接收电路对初级线圈的反射阻抗，效果如图8所示。Then, in this step, the gain of the wireless receiving circuit between the output voltage VR and the open circuit voltage Vsoc of the secondary coil is obtained, and the effect is shown in Figure 7; and the reflected impedance of the wireless receiving circuit to the primary coil, the effect is shown in Figure 8.

参见图7，横坐标为频率，图7左侧纵坐标为增益，图7右侧纵坐标为相位。曲线71为输出电压与开路电压的增益，在0～35KHz之间时处于线性增加状态，在35KHz～510KHz之间时处于平缓状态且约等于1(即超过设定增益阈值，如0.9)，在510KHz～60MHz之间时处于线性减小状态。曲线72表示增益的相位，或者说无线接收电路的输出电压与开路电压的相位差。Referring to Figure 7, the abscissa is frequency, the ordinate on the left side of Figure 7 is gain, and the ordinate on the right side of Figure 7 is phase. Curve 71 is the gain of the output voltage and the open circuit voltage. It is in a linear increasing state between 0 and 35KHz. It is in a flat state and is approximately equal to 1 (that is, it exceeds the set gain threshold, such as 0.9) between 35KHz and 510KHz. It is in a linear decreasing state between 510KHz and 60MHz. Curve 72 represents the phase of the gain, or the phase difference between the output voltage of the wireless receiving circuit and the open circuit voltage.

参见图8，横坐标为频率，图8左侧纵坐标为增益，图8右侧纵坐标为相位。曲线81表示开路电压与电流的比值(即无线接收电路对初级线圈的反射阻抗)，在35KHz～510KHz之间时处于平缓状态；曲线82表示开路电压与电流的相位差。Referring to Figure 8, the abscissa is frequency, the ordinate on the left side of Figure 8 is gain, and the ordinate on the right side of Figure 8 is phase. Curve 81 represents the ratio of open circuit voltage to current (that is, the reflected impedance of the wireless receiving circuit to the primary coil), which is in a gentle state between 35KHz and 510KHz; curve 82 represents the phase difference between open circuit voltage and current.

结合图8和图9所示，在35KHz～510KHz这个较宽的频率范围之间，无线接收电路的输出电压约等于开路电压，无线接收电路对初级线圈的反射阻抗近似为纯电阻。也就是说，本公开中无线接收电路所接收的能量几乎全部输出到负载。As shown in Figure 8 and Figure 9, in the wide frequency range of 35KHz to 510KHz, the output voltage of the wireless receiving circuit is approximately equal to the open circuit voltage, and the reflected impedance of the wireless receiving circuit to the primary coil is approximately pure resistance. That is to say, almost all the energy received by the wireless receiving circuit in the present disclosure is output to the load.

可理解的是，图4所示实施例仅描述了固定中心工作频率、电感器件L1和负载的电阻值的情况下，得到了图7和图8所示的曲线。在一实施例中，本公开还可以调整第一截止频率、第二截止频率和负载的电阻值中至少一项的取值，得到所述无线接收电路的多组候选参数值。然后，针对各组候选参数值，可以获取候选参数值对应无线接收电路的输出电压和开路电压的增益以及等效电阻。之后，当增益位于设定增益范围且等效电阻位于设定电阻范围时，可以确定候选参数值为无线接收电路的目标参数值。It can be understood that the embodiment shown in Figure 4 only describes the case where the central operating frequency, the resistance value of the inductor device L1 and the load are fixed, and the curves shown in Figures 7 and 8 are obtained. In one embodiment, the present disclosure can also adjust the value of at least one of the first cutoff frequency, the second cutoff frequency and the resistance value of the load to obtain multiple sets of candidate parameter values for the wireless receiving circuit. Then, for each set of candidate parameter values, the gain and equivalent resistance of the output voltage and open circuit voltage of the wireless receiving circuit corresponding to the candidate parameter value can be obtained. Afterwards, when the gain is within the set gain range and the equivalent resistance is within the set resistance range, the candidate parameter value can be determined to be the target parameter value of the wireless receiving circuit.

参见图9，横坐标表示频率，纵坐标表示反射阻抗。当中心工作频率Fc和电感器件L ₁分别为158.1kHz和10.61uH时，在不同R、F _H和F _L下V _R/V _SOC和V _SOC/I ₁的幅值、相角频率响应。当F _H和F _L变大时即工作频率范围扩大时，负载的电阻值需要相应变大，图9中所示各曲线的电阻值依次为3.33、6.67和20欧姆，以保持V _R/V _SOC和V _SOC/I ₁处于平缓状态。基于图9所示的多条曲线。结合图9所示的参数值，可以确定电阻值为20欧姆时对应的电路为最终的无线接收电路。 Referring to Figure 9, the abscissa represents frequency, and the ordinate represents reflection impedance. When the central operating frequency Fc and the inductor device L ₁ are 158.1kHz and 10.61uH respectively, the amplitude and phase angle frequency responses of _VR /V _SOC and V _SOC /I ₁ under different R, F _H and F _L. When F _H and F _L become larger, that is, when the operating frequency range expands, the resistance value of the load needs to become larger accordingly. The resistance values of each curve shown in Figure 9 are 3.33, 6.67 and 20 ohms in order to maintain V _R /V _SOC and V _SOC /I ₁ are in a flat state. Based on the multiple curves shown in Figure 9. Combined with the parameter values shown in Figure 9, it can be determined that the corresponding circuit when the resistance value is 20 ohms is the final wireless receiving circuit.

参见图10，横坐标表示频率，纵坐标表示增益。当中心工作频率Fc和电感器件L ₁分别为158.1kHz和10.61uH时，电感器件L1和负载R的电阻值不变时，可以将中心频率F _C和截止频率F _L、F _H设计为不同的值，以保持V _R/V _SOC和V _SOC/I ₁处于平缓状态。基于图10所示的多条曲线。结合图10所示的曲线，可以确定F _L为50kHz且F _H为500kHz时对应的电路为最终的无线接收电路。 Referring to Figure 10, the abscissa represents frequency and the ordinate represents gain. When the central operating frequency Fc and the inductor device _L1 are 158.1kHz and 10.61uH respectively, and the resistance values of the inductor device L1 and the load R remain unchanged, the center frequency _Fc and cutoff frequencies F _L and F _H can be designed to be different value to keep V _R /V _SOC and V _SOC /I ₁ in a flat state. Based on the multiple curves shown in Figure 10. Combined with the curve shown in Figure 10, it can be determined that the corresponding circuit when F _L is 50kHz and F _H is 500kHz is the final wireless receiving circuit.

至此，本公开实施例提供的方案提供的无线接收电路可以耦合第一截止频率和第二截止频率之间较宽范围频率内的电磁信号，可以适用不同工作频率的无线充电设备或者充电协议，有利于提高无线接收电路的兼容性；并且，本实施例中，输出电压与开路电压的增益位于设定增益范围之内，即使输出电压接近或等于开路电路，可以保证无线接收电路的接收效率和充电速率，有利于提升使用体验。So far, the wireless receiving circuit provided by the solution provided by the embodiment of the present disclosure can couple electromagnetic signals in a wide range of frequencies between the first cutoff frequency and the second cutoff frequency, and can be applied to wireless charging equipment or charging protocols with different operating frequencies.
