Description

Technical Field

[0001] This invention relates to the field of electromagnetic shock technology, specifically to a control device, method, electronic device, and medium for a pulse power supply system. Background Technology

[0002] In the field of high-speed impact testing, in order to verify the performance of the test sample under extreme mechanical environment, it is necessary to apply instantaneous high-speed overload impact to the test sample through test equipment so that the test sample generates the rated acceleration value. This process is a key link in evaluating the reliability of the test sample.

[0003] With the development of pulsed power technology, using ultra-high power pulsed power supply to drive electromagnetic actuators has become a feasible technical path to achieve high-speed impact action. In existing impact test platforms, the test specimen is usually placed in the middle of the platform, with two sets of coils configured at the left and right ends respectively. The two sets of coils are responsible for positive and negative impact loading functions, respectively. For example, in the positive loading stage, current is passed through the left coil to generate electromagnetic driving force, causing the impact platform to move to the right; in the negative loading stage, reverse current is passed through the right coil, thereby applying a negative wave impact to the test specimen.

[0004] As the core control unit and kinetic energy output source of high-speed impact testing, the pulse power supply system must simultaneously meet the energy supply requirements of the impact platform for both positive instantaneous acceleration and negative impact. Furthermore, its positive and reverse discharge capabilities must be flexibly adjustable in the control system to adapt to the differentiated requirements for positive acceleration energy and negative impact energy under different test scenarios.

[0005] In specific impact test applications, once the load coil specifications and main circuit device parameters are determined, the discharge pulse amplitude and pulse width parameters corresponding to the system's forward acceleration and reverse impact energies are initially defined. Therefore, how to achieve precise control of the impact energy magnitude and impact width through more convenient parameter adjustment methods has become a pressing technical problem for current pulse power supply systems. Summary of the Invention

[0006] In view of the above, the present disclosure provides a control device, method, electronic device and medium for a pulse power system, which at least partially solves the problems existing in the prior art.

[0007] In a first aspect, embodiments of this disclosure provide a control device for a pulse power supply system, comprising: The load coil (1), loop inductor (2), switching assembly (3), freewheeling assembly (4), loop resistor (5), capacitor bank protection assembly (9), charging protection assembly (10), charging control switch (11), DC charging power supply (12), and multiple capacitor banks; The load coil (1), the loop inductor (2), the switch assembly (3), the freewheeling assembly (4), and the loop resistor (5) are connected in sequence. The plurality of capacitor banks are respectively connected to the capacitor bank protection assembly (9), the charging protection assembly (10), and the charging control switch (11). The DC charging power supply (12) is respectively connected to the load coil (1), the loop resistor (5), the plurality of capacitor banks, and the charging control switch (11). The load coil (1) includes a positive wave load coil and a negative wave load coil.

[0008] According to a specific implementation of this disclosure, the DC charging power supply (12) charges the corresponding capacitor bank through the charging control switch (11). After the charging voltage of the capacitor bank reaches the preset charging voltage value, the corresponding charging control switch (11) is opened and the switch assembly (3) is closed, and the multiple capacitor banks discharge to the load coil (1).

[0009] According to one specific implementation of this disclosure, each of the plurality of capacitor banks includes a different number of capacitors. By controlling the number of capacitors participating in the discharge process, the discharge pulse width of the pulse power supply system can be adjusted.

[0010] According to a specific implementation of this disclosure, the charging voltage of the capacitor is controlled by adjusting the output parameters of the DC charging power supply (12), thereby achieving regulation of the output current amplitude of the pulse power supply system.

[0011] Secondly, embodiments of this disclosure provide a control method for a pulse power supply system, comprising: The capacitor charging voltage of the DC charging power supply is set via the host computer. The host computer controls the charging control switch to be turned on, and the capacitors in the capacitor bank corresponding to the charging control switch are charged. The voltage of the capacitor bank is monitored. When the charging voltage of the capacitor bank reaches the preset charging voltage value, the charging control switch corresponding to the capacitor bank is disconnected by the host computer. When the upper computer control switch assembly is turned on, the capacitor bank, which has completed charging, begins to release electrical energy to the load coil. The load coil includes a positive wave load coil and a negative wave load coil. The current provided by the pulse power system drives the positive wave load coil and the negative wave load coil to realize positive acceleration and negative wave impact motion of the sample under test.

[0012] According to one specific implementation of this disclosure, each of the plurality of capacitor banks includes a different number of capacitors, and the host computer adjusts the discharge pulse width of the pulse power system by controlling the number of capacitors participating in the discharge process.

[0013] According to one specific implementation of this disclosure, the host computer adjusts the output parameters of the DC charging power supply to control the charging voltage of the capacitor bank, thereby regulating the output current amplitude of the pulse power supply system.

[0014] Thirdly, embodiments of this disclosure provide an electronic device, the electronic device comprising: At least one processor; and, The memory is communicatively connected to the at least one processor; wherein, The memory stores instructions that can be executed by the at least one processor to enable the at least one processor to perform the control method of the pulse power system described above.

[0015] Fourthly, embodiments of this disclosure provide a non-transitory computer-readable storage medium storing computer instructions for causing the computer to execute the aforementioned control method for a pulsed power supply system.

[0016] In summary, compared with the prior art, this embodiment has the following advantages: 1. Breakthrough in pulse width adjustment bottleneck, meeting diverse testing needs, solving the problem that early technologies could only adjust impact energy, and filling the technical gap of uncontrollable pulse width; Taking the forward acceleration capacitor bank as an example, six different pulse width adjustments can be achieved through three types of capacitor grouping designs. The reverse impact energy can also achieve multiple pulse width adjustments using the same method, covering the parameter requirements of more test scenarios.

[0017] 2. The control method is flexible and the parameter adjustment is precise and controllable. By controlling the charging voltage of the capacitor, the output current can be directly adjusted, thereby precisely controlling the intensity of the impact energy. The operation is simple and highly accurate. By setting the number of capacitors participating in the discharge through the control system, the pulse width can be flexibly adjusted without modifying the hardware structure, thus improving the test efficiency.

[0018] In summary, this embodiment achieves dual control of impact energy and pulse width time, and the control method is flexible and precise. The impact energy is controlled by DC voltage, and the pulse width is controlled by the number of discharge capacitors, which can meet the needs of more test scenarios. Attached Figure Description

[0025] It should also be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of this disclosure. The drawings only show the components related to this disclosure and are not drawn according to the number, shape and size of the components in actual implementation. In actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0026] Furthermore, specific details are provided in the following description to facilitate a thorough understanding of the examples. However, those skilled in the art will understand that the described aspects can be practiced without these specific details.

[0027] Please see Figure 1 This application provides an embodiment of a control device for a prior art pulse power supply system, such as... Figure 1 The control device of the pulse power system shown includes: positive and negative wave load coils 1, loop inductor 2, switching assembly 3, freewheeling assembly 4, loop resistor 5, capacitor bank 6, charging protection assembly 7, charging control switch 8, and DC charging power supply 9.

[0028] exist Figure 1 In the illustrated embodiment, based on the impact acceleration parameters required for the experiment, the charging voltage value of the DC power supply 9 is preset in the host computer's operating software. The software sends a command to close the charging control switch 8, initiating the charging process for the capacitor bank 6. The host computer's control system can monitor the voltage of the capacitor bank 6 in real time. When the charging voltage of the capacitor bank 6 reaches the preset value, it automatically triggers a stop-charging procedure and controls the charging control switch 8 to open via software commands, completing the energy storage phase.

[0029] The host computer sends a discharge command to control the switch assembly 3 to close, and the capacitor bank 6 starts to discharge. The discharge current is fed into the positive and negative wave load coils 1, which convert electrical energy into electromagnetic force, and then into kinetic energy that requires the specific acceleration of the sample under test.

[0030] The device is equipped with a set of load coils at both ends. The left coil is responsible for positive impact loading. When energized, it generates an electromagnetic force to drive the impact platform to move to the right. The right coil is responsible for negative impact loading. When energized, it supplies current in the opposite direction to that of the left coil, generating a reverse electromagnetic force to decelerate the impact platform and eventually stop it. The driving current of both sets of coils is provided by a pulse power supply system. Under the drive of the above-mentioned electromagnetic actuator, the test sample completes the full test action of positive wave impact and negative wave impact.

[0031] pass Figure 1 As can be seen from the illustrated embodiment, the charging voltage of the DC power supply 9 can be adjusted via software on the host computer, thereby controlling the magnitude of the impact energy. Figure 1 In the illustrated embodiment, the pulse width of the impact cannot be adjusted.

[0032] To simultaneously control both the magnitude of the impact energy and the width of the impact pulse, see details below. Figure 2 , Figure 2 This is an illustration of a control device for a pulse power supply system provided in the first embodiment of the present invention. Figure 2 The control device of the pulse power system shown includes: load coil 1, loop inductor 2, switching assembly 3, freewheeling assembly 4, loop resistor 5, capacitor bank 6, capacitor bank 7, capacitor bank 8, capacitor bank protection assembly 9, charging protection assembly 10, charging control switch 11, and DC charging power supply 12.

[0033] like Figure 2 As shown, load coil 1, loop inductor 2, switch assembly 3, freewheeling assembly 4 and loop resistor 5 are connected in sequence. Capacitor group 6, capacitor group 7 and capacitor group 8 are respectively connected to the corresponding capacitor group protection assembly 9, charging protection assembly 10 and charging control switch 11. DC charging power supply 12 is connected to load coil 1, loop resistor 5, capacitor group 6, capacitor group 7, capacitor group 8 and charging control switch 11.

[0034] It should be noted that load coil 1 includes a positive wave load coil and a negative wave load coil.

[0035] The DC charging power supply 12 charges the corresponding capacitor groups 6, 7 and 8 through the charging control switch 11. After the charging voltage of the corresponding capacitor groups 6, 7 and 8 reaches the preset charging voltage value, the corresponding charging control switch 11 is opened, the switch assembly 3 is closed, and then the capacitor groups 6, 7 and 8 discharge to the load coil 1.

[0036] Capacitor banks 6, 7, and 8 contain different numbers of capacitors (for example, capacitor bank 6 contains 3 capacitors, capacitor bank 7 contains 5 capacitors, and capacitor bank 8 contains 7 capacitors). By controlling the number of capacitors participating in the discharge process, the discharge pulse width of the pulse power supply system can be adjusted. Figure 2 In the illustrated embodiment, capacitor bank 6 includes 3 capacitors, capacitor bank 7 includes 5 capacitors, and capacitor bank 8 includes 7 capacitors. Different combinations of these capacitors can achieve six pulse width adjustments.

[0037] Furthermore, by adjusting the output parameters of the DC charging power supply 12, the charging voltages of capacitor banks 6, 7, and 8 are controlled, thereby achieving regulation of the output current amplitude of the pulse power supply system.

[0038] It should be noted that the freewheeling component 4 can be a freewheeling diode or a module composed of them. When the discharge circuit is disconnected, the load coil generates an extremely high reverse induced electromotive force. The freewheeling component provides a low-impedance freewheeling path, allowing the magnetic field energy stored in the coil to be slowly released through the freewheeling circuit, preventing the reverse electromotive force from damaging the switching components or other electronic components.

[0039] The loop resistor 5 can be connected in series with a fixed resistor in the discharge circuit or with the equivalent resistance of the coil itself. In the initial stage of capacitor bank discharge, the loop impedance is extremely low, which can easily generate excessive peak current, potentially burning out the load coil or the pulse power supply system. The loop resistor can increase the total impedance, control the peak discharge current within the design allowable range, and protect the coil and power supply.

[0040] It can be seen Figure 2 The embodiment shown can simultaneously adjust the magnitude of the impact energy and the pulse width of the impact by controlling the number of capacitors involved in the discharge process and adjusting the output voltage of the DC charging power supply.

[0041] Secondly, this application also provides a control method for a pulse power supply system, see details below. Figure 3 This can be executed by an electronic device, which can act as a host computer, specifically by one or more processors within the electronic device, to achieve the following steps: S101. Set the capacitor charging voltage of the DC charging power supply via the host computer.

[0042] Specifically, the capacitor charging voltage of the DC charging power supply can be set via a host computer according to the experimental parameter requirements.

[0043] S102. The charging control switch is turned on by the host computer to charge the capacitors in the capacitor bank corresponding to the charging control switch.

[0044] The host computer can control the charging control switch to be turned on via operating software commands, and control the capacitor bank (e.g., the one corresponding to the charging control switch) to be charged. Figure 2 The capacitors in capacitor bank 6, capacitor bank 7, or capacitor bank 8 are charged.

[0045] S103. Monitor the voltage of the charging capacitor bank. When the charging voltage of the charging capacitor bank reaches the preset charging voltage value, disconnect the charging control switch corresponding to the charging capacitor bank through the host computer.

[0046] The host computer's control system monitors the charging voltage of the charging capacitor group selected by the charging switch in step S102. When the charging voltage of the charging capacitor group reaches the preset charging voltage value, the host computer controls the charging control switch connected in step S102 to disconnect through operation commands, thereby ending the charging of the corresponding capacitor group and completing the charging of the corresponding capacitor group.

[0047] S104. The upper computer controls the switch assembly to turn on, and the charging capacitor group that has completed charging begins to release electrical energy to the load coil. The load coil includes a positive wave load coil and a negative wave load coil. The current provided by the pulse power system drives the positive wave load coil and the negative wave load coil to realize positive acceleration and negative wave impact motion of the sample under test.

[0048] The host computer can control the switching components to turn on via operating software commands. The capacitor bank, which has completed charging in step S103, begins to release electrical energy to the load coil. The load coil includes a positive wave load coil and a negative wave load coil. After the load coil is energized, it can convert electrical energy into kinetic energy and drive the test sample to obtain a preset acceleration. The positive wave load coil and the negative wave load coil are respectively located at both ends (i.e., the left and right ends) of the electromagnetic actuator, and respectively undertake the positive loading function and the reverse loading function of the test sample.

[0049] When a positive loading action is required, a current in a preset direction is supplied to the positive wave load coil (left end coil), and the electromagnetic force generated by this current drives the impact platform to move in the first direction (to the right). When a reverse loading action (negative wave impact) is required, a current opposite to the direction of the forward current is supplied to the negative wave load coil (right end coil). The electromagnetic force generated by this reverse current drives the impact platform to move in a second direction opposite to the first direction.

[0050] The energizing action of both the positive wave load coil and the negative wave load coil is driven by the pulse current provided by the pulse power supply system; under the driving action of the electromagnetic actuator, the sample under test can sequentially complete the positive acceleration motion and the reverse impact (negative wave impact) motion.

[0051] It should be noted that the embodiments of this application include multiple capacitor banks, and each capacitor bank includes a different number of capacitors. The host computer controls the number of capacitors participating in the discharge process to adjust the discharge pulse width of the pulse power supply system.

[0052] In addition, the host computer adjusts the output parameters of the DC charging power supply to control the charging voltage of the capacitor bank, thereby regulating the output current amplitude of the pulse power supply system.

[0053] In summary, compared with the prior art, this embodiment has the following advantages: 1. Breakthrough in pulse width adjustment bottleneck, meeting diverse testing needs, solving the problem that early technologies could only adjust impact energy, and filling the technical gap of uncontrollable pulse width; Taking the forward acceleration capacitor bank as an example, six different pulse width adjustments can be achieved through three types of capacitor grouping designs. The reverse impact energy can also achieve multiple pulse width adjustments using the same method, covering the parameter requirements of more test scenarios.

[0054] 2. The control method is flexible and the parameter adjustment is precise and controllable. By controlling the charging voltage of the capacitor, the output current can be directly adjusted, thereby precisely controlling the intensity of the impact energy. The operation is simple and highly accurate. By setting the number of capacitors participating in the discharge through the control system, the pulse width can be flexibly adjusted without modifying the hardware structure, thus improving the test efficiency.

[0055] In summary, this embodiment achieves dual control of impact energy and pulse width time, and the control method is flexible and precise. The impact energy is controlled by DC voltage, and the pulse width is controlled by the number of discharge capacitors, which can meet the needs of more test scenarios.
