[0029] Please refer to Figure 1 , Figure 1The flowchart of a power distribution method in an embodiment of the present application. The present application provides a power distribution method, which is used to distribute the initial radio frequency electrical energy input at the input end into at least two target radio frequency electrical energies, and transmit the at least two target radio frequency electrical energies to at least two target loads among multiple loads. Among them, there are multiple power distribution branches connected between the input end and the multiple loads, and each power distribution branch is connected between the input end and the corresponding load. The input end can selectively connect to at least two target loads through at least two target power distribution branches. Among them, as Figure 1 shown, the power distribution method includes:

[0030] Step S100: Turn on at least two target power distribution branches between the input end and at least two target loads, and turn off the non-target power distribution branches between the input end and each non-target load.

[0031] Step S200: Determine the target impedance values of the corresponding target power distribution branches at least according to the target power values required by each target load.

[0032] Step S300: Adjust the impedance values of each target power distribution branch to the corresponding target impedance values, so as to distribute the initial radio frequency electrical energy input at the input end into at least two target radio frequency electrical energies through at least two target power distribution branches, and transmit the at least two target radio frequency electrical energies to at least two target loads correspondingly.

[0033] Thus, in the above power distribution method of the present application, by turning on at least two target power distribution branches between the input end and at least two target loads, and determining the target impedance values of the corresponding target power distribution branches at least according to the target power values required by each target load, and then adjusting the impedance values of each target power distribution branch to the corresponding target impedance values, so as to distribute the initial radio frequency electrical energy input at the input end into at least two target radio frequency electrical energies through at least two target power distribution branches, and transmit the at least two target radio frequency electrical energies to at least two target loads correspondingly, thus conveniently realizing uneven power distribution and being able to meet the power requirements of multiple loads.

[0034] Among them, the target impedance values of each target power distribution branch can be the same or different.

[0035] Please refer to Figure 2 , Figure 2 which is the flowchart showing another part of the steps of the power distribution method in another embodiment of the present application. Among them, Figure 2 Some of the steps in the shown flowchart can be, for example, as Figure 1Step S300 shown: The steps included after adjusting the impedance value of each target power distribution branch to the corresponding target impedance value, so as to distribute the initial radio frequency electrical energy input at the input end into at least two target radio frequency electrical energies through at least two target power distribution branches, and transmitting the at least two target radio frequency electrical energies to at least two target loads correspondingly. That is, as Figure 2 shown, after step S300, the power distribution method further includes:

[0036] Step S400: Perform impedance matching on at least each target load and each target power distribution branch.

[0037] Thus, in the above power distribution method of the present application, not only impedance matching can be performed on each load, but also impedance matching needs to be performed on each target power distribution branch at the same time to avoid large reflected power generated by multiple target power distribution branches.

[0038] Among them, Figure 2 Steps S100 to S300 in can be specifically referred to the relevant introduction in the foregoing Figure 1 and will not be elaborated here.

[0039] Please refer to Figure 3 , Figure 3 which is Figure 2 a sub-flowchart of step S400 in. The input end is used to connect to a radio frequency source to input the initial radio frequency electrical energy output by the radio frequency source. Among them, as Figure 2 , Figure 3 shown, step S400: Perform impedance matching on at least each target load and each target power distribution branch, which may specifically include:

[0040] Step S410: Perform impedance matching on the radio frequency source, each target load, and each target power distribution branch according to the impedance value of the radio frequency source, the impedance value of each target load, the impedance value of each target power distribution branch, and a preset characteristic impedance value.

[0041] Thus, in the above power distribution method of the present application, impedance matching is performed on the radio frequency source, each target load, and each target power distribution branch according to the preset characteristic impedance value to achieve a radio frequency output with less reflected power.

[0042] Among them, the preset characteristic impedance value can be 50Ω, 75Ω, etc., that is, the impedance values presented by the radio frequency source, multiple target loads, and multiple target power distribution branches after impedance matching.

[0043] Among them, Figure 3 Steps S100 to S300 in can be specifically referred to the relevant introduction in the foregoing Figure 1 and will not be elaborated here.

[0044] Please refer to Figure 4 as well, Figure 4 which is Figure 1 a sub - flowchart of step S200 in Figure 1 . As Figure 4 shown in

[0045] Step S200: Determine the target impedance values of the corresponding target power distribution branches according to at least the target power values required for each target load. Specifically, it may include:

[0046] Step S210: Determine the proportional relationship of the target power values of at least two target loads according to the target power values of each target load.

[0047] Step S220: Determine the proportional relationship of the target impedance values of the corresponding at least two target power distribution branches according to at least the proportional relationship of the target power values of at least two target loads.

[0048] Thus, in the above - mentioned power distribution method of the present application, according to the target power values of each target load in sequence, the proportional relationship of the target power values of at least two target loads can be determined, and further, the proportional relationship of the target impedance values of the corresponding at least two target power distribution branches can be determined, thereby obtaining the target impedance values of the corresponding target power distribution branches.

[0049] For example, if the proportional relationship of the target power values of three target loads is 6:4:3, then the proportional relationship of the target impedance values of the three target power distribution branches can be 100:150:200. Among them, the product of the target power value of any one target load and the target impedance value of the corresponding target power distribution branch is equal to a fixed product value. For example, the product of the target power value of the second target load and the target impedance value of the second target power distribution branch is 600, then the fixed product value is 600.

[0050] Among them, according to the target power values of each target load in step S210, that is, according to the target power values required for each target load.

[0051] Please refer to Figure 5 as well, Figure 5 which is Figure 4 a sub - flowchart of step S220 and step S230 in Figure 4 . As Figure 5 shown in

[0052] Step S221: Determine the proportional relationship of the target impedance values of at least two target power distribution branches corresponding thereto according to the proportional relationship of the target power values of at least two target loads and a preset characteristic impedance value.

[0053] Thus, in the power distribution method of the present application, when the preset characteristic impedance value is 50 Ω, the ratio of the reciprocals of each target power value in the proportional relationship of the target power values of at least two target loads is the proportional relationship of the target impedance values of at least two target power distribution branches corresponding thereto.

[0054] As Figure 4 、 Figure 5 shown, Step S230: Determine the target impedance value of each corresponding target power distribution branch according to at least the proportional relationship of the target impedance values of at least two corresponding target power distribution branches, which may specifically include:

[0055] Step S231: Determine the target impedance value of each corresponding target power distribution branch according to the proportional relationship of the target impedance values of at least two corresponding target power distribution branches, a preset quality factor, and the angular frequency of the initial radio frequency electric energy.

[0056] Thus, in the power distribution method of the present application, by means of the preset quality factor and the angular frequency of the initial radio frequency electric energy, the proportional relationship of the target impedance values of at least two corresponding target power distribution branches can be converted into the target impedance value of each corresponding target power distribution branch.

[0057] Wherein, the preset quality factor may be 1. According to the preset quality factor and the angular frequency of the initial radio frequency electric energy, the sum of the target impedance values of at least two corresponding target power distribution branches can be determined, and then the target impedance value of each corresponding target power distribution branch can be determined according to the proportional relationship of the target impedance values of at least two corresponding target power distribution branches.

[0058] Wherein, Figure 5 The steps in Figure 4 may be specifically referred to the relevant introduction in the foregoing

[0059] and will not be elaborated herein. Figure 6 , Figure 6 Please also refer to Figure 6 which shows a flowchart of another part of the steps of the power distribution method in another embodiment of the present application. The target impedance value of each target power distribution branch is obtained from an inductance value and a target capacitance value, and the target capacitance value is adjustable. Wherein, Figure 5The steps S231 shown: After determining the target impedance values of each corresponding target power distribution branch according to the proportional relationship of the target impedance values of at least two corresponding target power distribution branches, the preset quality factor, and the angular frequency of the initial radio frequency electrical energy, the included steps. That is, as Figure 6 shown, after step S231, the power distribution method further includes:

[0060] Step S240: Determine the target capacitance value of each corresponding target power distribution branch according to the target impedance value and the inductance value of each corresponding target power distribution branch.

[0061] Furthermore, as Figure 1 、 Figure 6 shown, adjusting the impedance value of each corresponding target power distribution branch in step S300 to the target impedance value may specifically include:

[0062] Step S310: Adjust the capacitance value of each corresponding target power distribution branch to the target capacitance value so that the impedance value of each corresponding target power distribution branch is the target impedance value.

[0063] Thus, in the above power distribution method of the present application, the target impedance value is obtained from the inductance value and the target capacitance value, and further, the target capacitance value of each corresponding target power distribution branch can be determined according to the target impedance value and the inductance value of each corresponding target power distribution branch to achieve the target impedance value.

[0064] The power distribution method of the present application realizes uneven power distribution conveniently through the above steps and can meet the power requirements of multiple loads.

[0065] Please refer to Figure 7 , Figure 7 which is a schematic diagram of a power distribution device in an embodiment of the present application.

The power distribution device 10 uses the above power distribution method to distribute the initial radio frequency electrical energy RF1 input from the input end 100 into at least two target radio frequency electrical energies RF2, and correspondingly transmits the at least two target radio frequency electrical energies RF2 to at least two target loads RL1 among the multiple loads RL.
