[0089] In order to make the purpose, technical solutions and advantages of the present application clearer, the embodiments of the present application will be described in further detail below with reference to the accompanying drawings.

[0090] First, several terms related to the present application are introduced and explained:

[0091] Pulse forming line: a pulse output is formed by the transmission of electromagnetic waves in the transmission line, which requires impedance matching, and the pulse duration should be less than one half of the total electrical length of the transmission line.

[0092] Transmission line transformer: a new element formed by combining transmission line and transformer organically on the basis of transmission line and transformer theory, which has the performance of transformer and the characteristics of transmission line.

[0093] The research and development idea of the present application includes: in order to output a high-voltage pulse, the pulse forming circuit usually needs to have a relevant module for boosting voltage, for example: using capacitors in parallel charging and series discharging, a MARX circuit for realizing high-voltage output, in which almost every capacitor is configured with a switch, which results in that the structure of the entire MARX circuit occupies a large volume, and the corresponding treatment instrument is difficult to be miniaturized.

[0094] Therefore, the existing pulse forming circuit is difficult to realize miniaturization of the circuit structure and output of higher voltage at the same time.

[0095] The pulse forming circuit and the control method, device, controller and storage medium provided by the present application aim to solve the above technical problems of the prior art.

[0096] The technical solutions of the present application and how the technical solutions of the present application solve the above technical problems will be described in detail below with specific embodiments. It should be pointed out that the following embodiments can be mutually referenced, borrowed or combined, and the same terms, similar features and similar implementation steps in different embodiments will not be described repeatedly.

[0097] The present application embodiment provides a pulse forming circuit 100, a structure diagram of the pulse forming circuit 100 is as shown in Figure 1 The pulse forming circuit 100 includes a first terminal 110, a second terminal 120, at least two pulse forming lines 130, at least two enable signal units 140, and a transmission line transformer 150.

[0098] The first terminal 110 is used for connecting a power supply.

[0099] The second terminal 120 is used for grounding.

[0100] The at least two pulse forming lines 130 are connected between the first terminal 110 and the second terminal 120 in sequence.

[0101] The at least two enable signal units 140, wherein one end of at least one enable signal unit 140 is connected between the first terminal 110 and the pulse forming line 130 closest to the first terminal 110, and the other end is grounded; one end of at least another enable signal unit 140 is connected with the second terminal 120, and the other end is grounded.

[0102] The transmission line transformer 150 is connected between any two pulse forming lines 130, and is used for outputting a target pulse to a load 500.

[0103] The pulse forming circuit 100 provided in the embodiment is connected to a power supply, and the power supply enters each pulse forming line 130 from the first terminal 110. Under the enablement of each enable signal unit 140, an initial pulse can be formed in the corresponding pulse forming line 130. The transmission line transformer 150 boosts the initial pulse to a target pulse that meets the requirement, and outputs the target pulse to the load 500.

[0104] The pulse forming circuit 100 provided in the embodiment can realize higher gain output of the pulse voltage, and greatly reduces the number of switches, which is conducive to reducing the size of the circuit.

[0105] It can be seen that, compared with the MARX circuit, the pulse forming circuit 100 provided in the embodiment can realize miniaturization of the circuit structure and output of higher voltage at the same time.

[0106] The transmission line transformer 150 in the pulse forming circuit 100 provided in the embodiment is connected between at least two pulse forming lines 130. One of the pulse forming lines 130 is connected to the power supply through the first terminal 110, and the other pulse forming line 130 is connected to the ground through the second terminal 120, so that the two pulse forming lines 130 can form initial pulses with opposite polarities under the enablement of the corresponding enable signal units 140. The specific forming method will be described in detail in the control method of the pulse forming circuit 100 provided in the embodiment below, and will not be described here.

[0107] It can be seen that the pulse forming circuit 100 provided in the embodiment is conducive to enriching the form of high-voltage pulses output to the load 500, and improving the application scenarios or treatment effects of the pulse forming circuit 100 provided in the embodiment.

[0108] The research and development idea of the present application also includes that the pulses output by the pulse forming circuit 100 are mainly formed in the pulse forming line 130, and the performance of the pulse forming line 130 will have an important influence on the pulses output by the pulse forming circuit 100. Therefore, the present application provides the following possible implementation manner for the pulse forming circuit 100:

[0109] In the pulse forming circuit 100 provided in the embodiment of the present application, at least one pulse forming line 130 includes a first wire, a second wire sleeved outside the first wire, and a first dielectric structure located between the first wire and the second wire.

[0110] The first wire is connected between the first terminal 110 and the second terminal 120, and the second wire is grounded.

[0111] In this embodiment, the at least one pulse forming line 130 includes a first wire and a second wire sleeved outside the first wire, that is, a coaxial line structure. The first wire is used for flowing power, and the second wire is grounded and forms a capacitive structure with the first wire under the isolation of the first dielectric structure. This not only helps to form a stable initial pulse in the first wire, but also helps to provide gain for the initial pulse, for example, to increase the voltage amplitude of the initial pulse, thereby helping the target pulse output by the pulse forming circuit 100 to achieve gain.

[0112] The research and development idea of the present application also includes that the performance of the enable signal unit 140 in the pulse forming circuit 100 can also have an important influence on the pulse output by the pulse forming circuit 100. Therefore, the present application provides the following possible implementation manner for the pulse forming circuit 100:

[0113] As shown in Figure 2 , in the pulse forming circuit 100 of the embodiment of the present application, the at least one enable signal unit 140 includes a controllable transistor 141.

[0114] The source of the controllable transistor 141 is connected to the pulse forming line 130, the drain of the controllable transistor 141 is grounded, and the gate of the controllable transistor 141 is configured to be signal-connected with the controller 310.

[0115] In this embodiment, the enable signal unit 140 adopts an enable structure including a controllable transistor 141, which can provide high-quality enable excitation support for forming a stable initial pulse in the pulse forming line 130 by using the advantages of the controllable transistor 141, such as small noise, low power consumption, large dynamic range, easy integration, no secondary breakdown phenomenon, and wide safe working area.

[0116] Moreover, after the gate of the controllable transistor 141 is configured to be signal-connected with the controller 310, the enable action can be realized according to the control signal of the controller 310, which helps to enrich the high-voltage pulse form output by the pulse forming circuit 100 to the load 500.

[0117] In some examples, the controllable transistor 141 can include a FET (Field Effect Transistor) or an IGBT (Insulated Gate Bipolar Transistor).

[0118] In some possible implementation manners, as shown in Figure 2 , the at least one enable signal unit 140 includes at least two controllable transistors 141 connected in parallel with each other.

[0119] In the embodiment, the at least two controllable transistors 141 adopt the parallel connection of the enable circuit structure, which is beneficial to realize the superposition of the enable action. For example, under the condition of providing the same frequency of enable excitation to the corresponding pulse forming line 130, compared with the enable circuit structure of a single controllable transistor 141, the working frequency of each controllable transistor 141 in the enable circuit structure of two parallel connected controllable transistors 141 is lower, which is beneficial to reduce the cost of each controllable transistor 141; under the condition of the same parameters of the controllable transistor 141, compared with the enable circuit structure of a single controllable transistor 141, the enable circuit structure of two parallel connected controllable transistors 141 can output superimposed enable frequency, so that the initial pulse of higher frequency is formed in the corresponding pulse forming line 130, and the output pulse frequency band of the pulse forming circuit 100 is widened.

[0120] In one example, one end of each controllable transistor 141 in the two parallel connected controllable transistors 141 is connected between the first terminal 110 and the pulse forming line 130 closest to the first terminal 110, and the other end is grounded.

[0121] In another example, one end of each controllable transistor 141 in the two parallel connected controllable transistors 141 is connected to the second terminal 120, and the other end is grounded.

[0122] The research and development idea of the present application also includes that in the process of pulse electric field treatment, different target regions may have different impedances of the corresponding load 500 due to differences in tissue morphology or individual differences, and the pulse forming circuit 100 needs to match the impedance of the corresponding load 500 to output the target pulse to the load 500, so as to provide more effective treatment effect. Therefore, the present application provides the following four possible implementation modes for the pulse forming circuit 100:

[0123] The first possible implementation mode is shown in FIG. 1, in which the pulse forming circuit 100 of the embodiment of the present application comprises a transmission line transformer 150 and a controllable transistor 141. Figure 3 The transmission line transformer 150 comprises a first inductive line and a second inductive line which constitute a transmission line structure, and a third inductive line and a fourth inductive line which constitute another transmission line structure.

[0124] The first inductive line (A1-A2) is connected between the pulse forming line 130 closest to the first terminal 110 and the load 500 in any two pulse forming lines 130.

[0125] The second inductive line (B2-B1) is connected between the load 500 and the pulse forming line 130 closest to the second terminal 120 in any two pulse forming lines 130.

[0126] The third inductive line (B3-B4) and the fourth inductive line (A4-A3) are connected in series between any two pulse forming lines 130 in turn.

[0127] The transmission line transformer 150 provided by the embodiment includes two transmission line structures, i.e., four ports and eight pins, and can achieve a 1:4 impedance transformation effect.

[0128] Specifically, as shown in Figure 3 Z in Two ends are two ports, and two parallel loops can be formed, i.e., Z in Loop 1 includes: Z in+ → A1→ A2→ Z Load+ → Z load- → B2→ B1→ Z in- ; Z in Loop 2 includes: Z in+ → B3→ B4→ A4→ A3→ Z in- . Assuming that the equivalent impedance of the port is Z, the impedance after parallel connection is 0.5Z.

[0129] Z load Two ends are two ports, and one series loop can be formed, i.e., Z Load Loop = Z Load+ → A2→ A1→ B3→ B4→ A4→ A3→ B1→ B2→ Z load- . Assuming that the equivalent impedance of the port is Z, the impedance after parallel connection is 2Z.

[0130] Therefore, the transmission line transformer 150 provided by the embodiment can achieve a 1:4 impedance transformation effect. in : Z Load .

[0131] The second possible implementation manner is shown in Figure 4 The pulse forming circuit 100 provided by the embodiment includes a fifth inductive line and a sixth inductive line forming a transmission line structure, a seventh inductive line and an eighth inductive line forming another transmission line structure, and a ninth inductive line and a tenth inductive line forming another transmission line structure.

[0132] The fifth inductive line (A1-A2) is connected between the pulse forming line 130 close to the first terminal 110 and the load 500 in any two pulse forming lines 130.

[0133] The sixth inductive line (C4-C3) is connected between the load 500 and the pulse forming line 130 close to the second terminal 120 in any two pulse forming lines 130.

[0134] The seventh inductive line (B1-B2) and the eighth inductive line (A4-A3) are connected in series between any two pulse forming lines 130 in turn, and the ninth inductive line (C1-C2) and the tenth inductive line (B4-B3) are also connected in series between any two pulse forming lines 130 in turn.

[0135] The transmission line transformer 150 provided by the embodiment includes three transmission line structures, i.e., six ports and twelve pins, and can realize a 1:9 impedance transformation effect.

[0136] Specifically, as shown in the figure, Figure 4 it is assumed that the equivalent impedance of each transmission line structure at the port is Z, and for Z in , three ports are combined into one port, i.e., Figure 4 A1, B1 and C1 are combined into one pin, A3, B3 and C3 are combined into one pin, and the two newly combined pins form one port, and the impedance of the port is 1 / 3 Z.

[0137] For Z load , three ports are also combined into one port, and the difference lies in that the three ports are connected in series, i.e., Figure 4 A4 is connected to B2, B4 is connected to C2, and the impedance of the port is 2Z. load Only A2 and C4 are connected respectively at both ends, and the impedance at this time is the cumulative impedance of the three ports, i.e., 3Z.

[0138] Therefore, the transmission line transformer 150 provided by the embodiment can realize a 1:9 impedance transformation effect. in :Z Load .

[0139] The third possible implementation manner is shown in the figure, Figure 5 In the pulse forming circuit 100 of the embodiment of the application, the transmission line transformer 150 includes an eleventh inductive line and a twelfth inductive line which constitute a transmission line structure.

[0140] The eleventh inductive line (A1-A2) is connected between any two pulse forming lines 130.

[0141] The twelfth inductive line (A4-A3) is connected between the pulse forming line 130 close to the first terminal 110 and the load 500 in any two pulse forming lines 130.

[0142] The transmission line transformer 150 provided by the embodiment includes two transmission line structures, i.e., two ports and four pins, and can realize a 1:4 impedance transformation effect.

[0143] Specifically, as shown in the figure, Figure 5 Z in Two ends are two ports, and two parallel loops can be formed, i.e., Zin Loop 1 includes: Z in+ →A1→A2→Z in- Z in Loop 2 includes: Z in+ →A4→A3→Z Load+ →Z load- →Z in- Assuming the equivalent impedance of the port is Z, the impedance after parallel connection is 0.5Z.

[0144] Z load With two ports at both ends, a series loop can be formed, i.e., Z. Load Loop = Z Load+ →A3→A4→A1→A2→Z load- Assume the equivalent impedance of the port is Z, and the impedance after parallel connection is 2Z.

[0145] Therefore, the transmission line transformer 150 provided in this embodiment can achieve Z in :Z Load The impedance transformation effect is 1:4.

[0156] In the pulse generating circuit 200 provided by the embodiment, the power supply module 210 provides power for the pulse forming circuit 100 to form a target pulse. Since the pulse generating circuit 200 includes any one of the pulse forming circuits 100 provided in the above embodiments, the implementation principle and beneficial effects are similar, and will not be described here.

[0157] In some possible implementation manners, as shown in Figure 7 , the power supply module 210 includes a direct current power supply unit 211 and a capacitor 212.

[0161] Based on the same inventive concept, the embodiment of the present application provides a pulse generator 300, a structural schematic diagram of which is shown in Figure 8 The pulse generator 300 includes a controller 310 and any one of the pulse generating circuits 200 provided in the above embodiments.

[0162] The controller 310 is in signal connection with the enable signal unit 140 of the pulse forming circuit 100 in the pulse generating circuit 200.

[0163] In the embodiment, the controller 310 can control the enable signal unit 140 of the pulse forming circuit 100 in the pulse generating circuit 200 to realize a designated enable action, which facilitates enrichment of the high-voltage pulse form output by the pulse forming circuit 100 to the load 500. The possible control method of the controller 310 will be described in detail in the control method of the pulse forming circuit 100 provided in the following embodiments, and thus is not described herein.

[0164] Since the pulse generator 300 includes any one of the pulse generating circuits 200 provided in the above embodiments, the implementation principle and beneficial effects thereof are similar, and thus are not described herein.

[0165] Based on the same inventive concept, the embodiment of the present application provides a control method of any one of the pulse forming circuits 100 provided in the above embodiments, a flowchart of which is shown in Figure 9 The method includes the following steps S101-S102.

[0166] S101: Control all the enable signal units in the pulse forming circuit to be disconnected, so as to charge at least part of the pulse forming lines.

[0167] The step S101 can realize sufficient conduction of the power supply module 210 to each pulse forming line 130, so that at least part of the pulse forming lines 130 can accumulate electric energy that can be used to form an initial pulse, and prepare for the next step S102.

[0168] S102: Control at least one enable signal unit to be enabled, so as to form an initial pulse in at least part of the pulse forming lines. The initial pulse forms a target pulse for output to the load after being transformed by the transmission line transformer.

[0169] The step S102 can be realized by controlling the enable signal unit 140 to act, so that the electric energy accumulated in the pulse forming line 130 can form an initial pulse under the enable excitation of the corresponding enable signal unit 140, and the initial pulse is boosted to a target pulse meeting the demand by the transmission line transformer 150 to output to the load 500.

[0170] Through the above steps S101 and S102, the pulse voltage can be output with higher gain by the cooperation of the pulse forming line 130 and the transmission line transformer 150, and the number of switches is greatly reduced, which is conducive to reducing the circuit size.

[0171] Since the transmission line transformer 150 in the pulse forming circuit 100 provided by the foregoing embodiment is connected between at least two pulse forming lines 130, one of which is connected to the power supply through the first terminal 110 and the other of which is connected to the ground through the second terminal 120, the two pulse forming lines 130 can form initial pulses with opposite polarities under the enable excitation of the corresponding enable signal unit 140, so that the high-voltage pulse form output by the pulse forming circuit 100 to the load 500 can be more abundant by the specific control method of the enable signal unit 140, thereby improving the application scenarios or treatment effects of the pulse forming circuit 100.

[0172] Therefore, the specific control method of the enable signal unit 140 in the pulse forming circuit 100 is provided with the following possible implementation manners:

[0173] In the first possible implementation manner, the control of the at least one enable signal unit in the step S102 includes:

[0174] The enable signal unit connected at one end between the first terminal and the pulse forming line closest to the first terminal and grounded at the other end is enabled, so that the first-polarity initial pulse is formed in at least part of the pulse forming line, and the first-polarity target pulse for output to the load is formed after the transmission line transformer.

[0175] In the embodiment, by enabling the enable signal unit 140 connected at one end between the first terminal 110 and the pulse forming line 130 closest to the first terminal 110 and grounded at the other end, the electric energy accumulated in at least part of the pulse forming line 130 connected between the first terminal 110 and the transmission line transformer 150 can form the first-polarity initial pulse, and the first-polarity target pulse output by the pulse forming circuit 100 to the load 500 can meet the scene demand or treatment demand.

[0176] It should be noted that the "first polarity target pulse" in this embodiment refers to a target pulse with a first polarity, for example, positive; the "second polarity target pulse" described below refers to a target pulse with a second polarity, which is opposite to the first polarity, for example, negative.

[0177] Based on the above first possible implementation, the control of the enable signal unit connected at one end between the first terminal and the pulse forming line closest to the first terminal and grounded at the other end includes:

[0178] Controlling at least two controllable transistors in parallel with each other in the enable signal unit to alternately enable, so that at least part of the pulse forming line connected between the first terminal and the transmission line transformer forms a first frequency initial pulse, and the first frequency initial pulse forms a first frequency target pulse for output to the load after the transmission line transformer.

[0179] In this embodiment, by controlling at least two controllable transistors 141 in parallel with each other in the enable signal unit 140 connected at one end between the first terminal 110 and the pulse forming line 130 closest to the first terminal 110 and grounded at the other end, the superposition of the enable action is realized by the parallel connection of the enable circuit structure, so that the electrical energy accumulated in at least part of the pulse forming line 130 connected between the first terminal 110 and the transmission line transformer 150 forms a first frequency initial pulse. In the case of the same parameters of the controllable transistor 141, the frequency of the first frequency initial pulse is higher than that of the initial pulse formed by the enable excitation of a single controllable transistor 141, and further the first frequency target pulse output by the pulse forming circuit 100 to the load 500 meets the scene needs or treatment needs.

[0180] In the second possible implementation, the control of the at least one enable signal unit in the above step S102 includes:

[0181] Controlling the enable signal unit connected at one end to the second terminal and grounded at the other end to enable, so that at least part of the pulse forming line forms a second polarity initial pulse, and the second polarity initial pulse forms a second polarity target pulse for output to the load after the transmission line transformer.

[0182] In this embodiment, by controlling the enable signal unit 140 connected at one end to the second terminal 120 and grounded at the other end, the electrical energy accumulated in at least part of the pulse forming line 130 connected between the transmission line transformer 150 and the second terminal 120 can form a second polarity initial pulse, and further the second polarity target pulse output by the pulse forming circuit 100 to the load 500 meets the scene needs or treatment needs.

[0183] It should be noted that the "second polarity target pulse" in this embodiment refers to a target pulse with a second polarity, which is opposite to the first polarity in the "first polarity target pulse" described above. For example, if the first polarity is positive, the second polarity is negative, and vice versa.

[0184] Based on the above second possible implementation, the control of the enable signal unit connected between the first terminal and the second terminal and grounded at the other end includes:

[0185] The control of the at least two controllable transistors connected in parallel alternately enables to form a second frequency initial pulse in at least part of the pulse forming line connected between the transmission line transformer and the second terminal, and the second frequency initial pulse forms a second frequency target pulse for output to the load after passing through the transmission line transformer.

[0186] In this embodiment, by controlling the at least two controllable transistors 141 connected in parallel alternately in the enable signal unit 140 connected between the first terminal and the second terminal 120 and grounded at the other end, the superposition of enable actions is realized by using the parallel connection of the enable circuit structure, so that the electrical energy accumulated in at least part of the pulse forming line 130 connected between the transmission line transformer 150 and the second terminal 120 forms a second frequency initial pulse. In the case where the parameters of the controllable transistors 141 are the same, the frequency of the second frequency initial pulse is higher than that of the initial pulse formed by the enable excitation of a single controllable transistor 141, and further the second frequency target pulse output by the pulse forming circuit 100 to the load 500 meets the scene needs or treatment needs.

[0187] In the third possible implementation, the control of the at least one enable signal unit in the above step S102 includes:

[0188] The control of the first enable signal unit and the second enable signal unit alternately enables to form a first polarity initial pulse in at least part of the pulse forming line connected between the first terminal and the transmission line transformer, and a second polarity initial pulse in at least part of the pulse forming line connected between the transmission line transformer and the second terminal, and the first polarity initial pulse and the second polarity initial pulse respectively form a first polarity target pulse and a second polarity target pulse for output to the load after passing through the transmission line transformer.

[0189] The one end of the first enable signal unit is connected between the first terminal and the pulse forming line closest to the first terminal, and the other end is grounded. The one end of the second enable signal unit is connected to the second terminal, and the other end is grounded.

[0190] In the embodiment, the control alternately enables the first enable signal unit 140 having one end connected between the first terminal 110 and the pulse forming line 130 closest to the first terminal 110 and the other end grounded and the second enable signal unit 140 having one end connected to the second terminal 120 and the other end grounded, so that the electric energy accumulated in at least part of the pulse forming line 130 connected between the first terminal 110 and the transmission line transformer 150 forms a first-pole initial pulse, and the electric energy accumulated in at least part of the pulse forming line 130 connected between the transmission line transformer 150 and the second terminal 120 forms a second-pole initial pulse opposite in polarity to the first-pole initial pulse, the first-pole initial pulse and the second-pole initial pulse are alternately formed, and then the pulse forming circuit 100 alternately outputs a first-pole target pulse and a second-pole target pulse to the load 500 to meet the scene requirement or the treatment requirement.

[0191] It can be understood that, on the basis of the embodiment, at least two controllable transistors 141 in parallel with each other in the first enable signal unit 140 can be alternately enabled during the control of the first enable signal unit 140, or at least two controllable transistors 141 in parallel with each other in the second enable signal unit 140 can be alternately enabled during the control of the second enable signal unit 140, so as to respectively increase the frequency of the first-pole target pulse or the second-pole target pulse to meet the scene requirement or the treatment requirement.

[0219] By applying the embodiments of the present application, the following beneficial effects can be achieved at least:

[0220] 1. Compared with the MARX circuit, the pulse forming circuit 100 proposed in the present application adopts the cooperation of the pulse forming line 130 and the transmission line transformer 150, which can realize higher gain output of the pulse voltage and greatly reduce the number of switches, which is conducive to reducing the circuit size, that is, the circuit structure miniaturization and higher output voltage can be realized at the same time; Specifically, under the enable excitation of the enable signal unit 140, an initial pulse is formed in the pulse forming line 130, and the initial pulse is boosted to the target pulse that meets the demand through the transmission line transformer 150.

[0221] 2. The transmission line transformer 150 in the pulse forming circuit 100 proposed in the present application is connected between at least two pulse forming lines 130, one of which is connected to the power supply and the other of which is connected to the ground, so that the two pulse forming lines 130 can form initial pulses with opposite polarities under the enable excitation of the corresponding enable signal unit 140, which is conducive to enriching the high-voltage pulse form output to the load 500 and improving the application scenarios or treatment effect of the pulse forming circuit 100 proposed in the present application.

[0222] 3. The enable signal unit 140 adopts an enable structure including a controllable transistor 141, which can utilize the advantages of the controllable transistor 141 such as small noise, low power consumption, large dynamic range, easy integration, no secondary breakdown phenomenon, and wide safe working area, to provide high-quality enable excitation support for forming stable initial pulses in the pulse forming line 130.

[0223] 4. At least two controllable transistors 141 are connected in parallel in an enable circuit structure, which is beneficial for achieving superposition of enable actions. For example, when the corresponding pulse forming line 130 is provided with the same frequency of enable excitation, compared with the enable circuit structure of a single controllable transistor 141, the operating frequency of each controllable transistor 141 in the enable circuit structure of two controllable transistors 141 connected in parallel is lower, which is beneficial for reducing the cost of each controllable transistor 141; when the parameters of the controllable transistors 141 are the same, compared with the enable circuit structure of a single controllable transistor 141, the enable circuit structure of two controllable transistors 141 connected in parallel can output superimposed enable frequencies, so that the corresponding pulse forming line 130 is enabled to form an initial pulse of a higher frequency, thus widening the output pulse frequency band of the pulse forming circuit 100.
