Description

Technical Field

[0001] This utility model relates to the field of particle accelerator technology, and in particular to a particle accelerator coil / magnet power supply device. Background Technology

[0002] Most existing particle accelerator magnet power supplies on the market are non-standard integrated power supply designs, developed on a customized basis, using different functional components assembled as needed, making debugging difficult. Due to the lack of unified standards, they have poor versatility, a mixed technical system, and complex structural and process control. Furthermore, integrated power supply designs are usually compact, resulting in high power density and concentrated heat generation, making heat dissipation a significant issue. Inadequate heat dissipation design can lead to excessively high temperatures inside the chassis, affecting power supply performance and lifespan, and even causing malfunctions. Simultaneously, insufficient space during assembly increases the difficulty of operation and necessitates the disassembly of multiple components for later maintenance and upgrades, increasing maintenance costs. The internal component connections use various cables; limited space leads to messy wiring, affecting airflow. Complex cables are susceptible to electromagnetic interference, wear, and aging, resulting in poor contact, abnormal signal transmission, and impacting power supply performance. This, in turn, reduces the stability and reliability of particle accelerator operation, increasing the risk of downtime and operational interruptions. Utility Model Content

[0003] To address the technical problems existing in the prior art, the purpose of this utility model is to provide a particle accelerator coil / magnet power supply device, proposing the concept of a modular structure for particle accelerator coil / magnet power supply, thus solving the structural problems of existing non-standard integrated power supplies.

[0004] The objective of this utility model is achieved through the following technical solution: A particle accelerator coil / magnet power supply device includes a chassis and a first backplate, a second backplate, several control modules, several functional modules, and several bus power modules placed inside. The first backplate and the second backplate are arranged face-to-face inside the chassis, dividing the inner cavity of the chassis into a first compartment, a second compartment, and a third compartment. The several control modules are placed in the first compartment and interconnected through the first backplate. The several functional modules are placed in the third compartment and respectively connected to the second backplate. The second compartment is located between the first backplate and the second backplate, serving as a wiring operation space. By adjusting the wiring on the second backplate, different circuits and different polarity power supply modes can be switched, or by changing the parameters of the modules, the overall function and output parameters of the power supply device can be changed.

[0005] Specifically, by changing the routing of the second backplane, the switching between BUCK circuit and H-bridge circuit is realized in terms of circuit operation mode, and the switching between unipolar power supply and bipolar power supply is realized in terms of function.

[0006] Specifically, the functional module includes a VAC board, at least two CAP boards, at least two power boards, at least two driver boards, a CRC absorption board, and an output sampling board; the power boards and driver boards are combined into a functional module, and shielding covers that are fixed by clips are respectively installed on the outer layer of the power boards and driver boards.

[0007] Preferably, the plurality of functional modules are connected to the second backplane through a plurality of quick-connect terminals. Each functional module is independent of the others. The quick-connect terminals are interconnected through copper busbars. By adjusting the connection method of the copper busbars, the connection switching between different functional modules can be achieved.

[0008] Specifically, the bus power module includes several DC power supplies; for DC power supplies without quick-connect structures, the DC power supply is connected to the second backplane via a copper busbar or cable, thereby connecting the bus power module to the functional module; for DC power supplies with quick-connect structures, a third backplane is provided, and the DC power supply with quick-connect structures is connected to the third backplane via several quick-connect terminals, and the third backplane is connected to the second backplane via a copper busbar, thereby connecting the bus power module to the functional module.

[0009] Furthermore, the DC power supply without a quick-connect structure is a high-power power supply, located at the bottom of the chassis and below the functional module; the DC power supply with a quick-connect structure has a lower power and a smaller volume than the DC power supply without a quick-connect structure, and is located next to the control module.

[0010] Furthermore, by adjusting the connection method of the copper busbars and / or the parameters of each module, different power output modes can be achieved, including:

[0011] Mode 1: One DC power supply and one H-bridge module are converted into two synchronous BUCK parallel outputs, with unipolar output;

[0012] Mode 2: Two DC power supplies, one H-bridge module is converted into two synchronous BUCK parallel outputs, unipolar output;

[0013] Mode 3: Two DC power supplies, two H-bridge modules are converted into four synchronous BUCK parallel outputs, unipolar output;

[0014] Mode 4: Two DC power supplies, two H-bridge modules are converted into two sets of synchronous BUCK series outputs, where each set consists of two synchronous BUCKs connected in parallel, with unipolar output;

[0015] Mode 5: One DC power supply, one H-bridge module output, bipolar output;

[0016] Mode 6: Two DC power supplies, one H-bridge module connected in parallel for bipolar output;

[0017] Mode 7: Two DC power supplies, two H-bridge modules connected in parallel for bipolar output;

[0018] Mode 8: Two DC power supplies, two H-bridge modules connected in series for bipolar output.

[0019] Furthermore, both the control module and the functional module are housed in the chassis as boards and are installed using a quick-plug method.

[0020] Specifically, the chassis is equipped with several crossbeams and several guide rails. The crossbeams and guide rails are erected perpendicularly to each other to form a frame for fixing the control module and function module. The board-type control module or function module is inserted into the upper and lower guide rails respectively. When it is necessary to replace the control module or function module, the corresponding panel of the chassis can be removed and the control module or function module can be pulled out or installed along the guide rails.

[0021] Furthermore, the control module includes a signal processing board, a control board, and an ADC acquisition board. The ADC acquisition board performs high-precision and high-speed sampling of the key input and output signals of the power supply and sends them to the control board for processing. The control board outputs relevant control signals to control the overall operation of the power supply. The signal processing board is used to handle the power supply's fault protection, fault interlocking, and protection and processing of some analog sampling signals. The first backplane and the second backplane are connected by copper busbars or coaxial cables to connect the control module with the functional modules.

[0022] Compared with the prior art, the present invention has at least the following beneficial effects:

[0023] 1. The modular design of this utility model not only facilitates the upgrading and modification of power supply systems, but also avoids the messy internal layout caused by traditional wiring, allowing for the planning of reasonable ventilation channels within the chassis and improving heat dissipation. By modularizing control components, functional components, and power supply components, the applicability of the power supply is expanded. Different circuits and power supply polarities can be switched by changing the wiring method, and the overall function and output parameters of the power supply device can be changed by altering the module parameters.

[0024] 2. In terms of the internal module layout of the power supply, the wiring and operation space is divided by the first and second backplanes. The operation space is ample, facilitating operation while also making the wiring more reasonable and safer. Moreover, the functional modules and control modules are separated. The front half of the chassis houses the control modules, while the rear half houses the functional modules. This design avoids electromagnetic interference from the high current and high voltage in the power modules to the control circuit, ensuring the stability and accuracy of the control circuit. Furthermore, power load fluctuations and temperature rise during operation can affect the circuit's operation; separating the two improves the overall reliability of the system.

[0025] 3. The copper busbar used in this utility model has high mechanical strength and is not easy to break or deform. In some harsh working environments or places with mechanical vibration, the copper busbar can maintain better connection because of its regular shape and size. Also, because the copper busbar is a one-piece molded structure, the possibility of errors is reduced during installation and fixing. Furthermore, because of its large heat dissipation area, its heat dissipation performance is better than that of wires, and the heat generated during high current transmission can be dissipated more quickly, which can effectively avoid electrical failures caused by overheating.

[0026] 4. The module wiring connection of this utility model also uses a plug-in card structure, which can be quickly installed and removed, and the power structure can be quickly adjusted. In addition, the bottom of the power supply uses a slide rail to calibrate the position of the bus power module, which not only saves time and effort during installation, but also avoids the possibility of incorrect wiring.

[0027] 5. This utility model has undergone actual on-site assembly, maintenance, upgrade and modification, power supply operating temperature test, power supply operation stability test, etc., and the test results are all superior to traditional integrated power supplies.

[0057] To facilitate understanding of this utility model, the technical solutions and advantages of the utility model will be further described in detail below with reference to the accompanying drawings and embodiments. Any mechanisms or methods not elaborated in this utility model can be referred to in the prior art. The specific structure and features of this utility model are illustrated below by way of example and should not constitute any limitation on this utility model. Furthermore, any technical feature mentioned below (including implicit or disclosed features), as well as any technical feature directly shown or implied in the figures, can be arbitrarily combined or deleted among these technical features to form more other embodiments that may not be directly or indirectly mentioned in this utility model. The accompanying drawings show preferred embodiments of this utility model. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this utility model.

[0058] like Figure 1-11 As shown, the particle accelerator coil / magnet power supply device of this embodiment includes a chassis 10 and a first backplate 21, a second backplate 22, several control modules 40, several functional modules 50, and several bus power modules 60 placed inside it. The first backplate 21 and the second backplate 22 are arranged face-to-face inside the chassis 10, dividing the interior of the chassis 10 into a first compartment 31, a second compartment 32, and a third compartment 33. The control modules 40 are placed in the first compartment 31 and interconnected with each other through the first backplate 21, while the functional modules 50 are placed in the third compartment 33 and connected to the second backplate 22 respectively. The second compartment 32, located between the first backplate 21 and the second backplate 22, serves as a wiring operation space. By adjusting the wiring on the second backplate 22, different circuits and different polarity power supply modes can be switched; by changing the parameters of the modules, the overall function and output parameters can be changed.

[0059] Specifically, the chassis 10 is a square container with six end faces, namely a front panel 11, a rear panel 12, an upper panel 13, a lower panel 14, and two side end panels 15.

[0060] The front panel 11 is horizontally divided into several independent components: a blind plate 111, a signal processing board panel 112, a control board panel 113, a data acquisition board panel 114, and a front ventilation panel 115. The front ventilation panel 115 has an array of ventilation holes 1150 for heat dissipation. Two front crossbeams 181 are arranged vertically on the inner wall of the front panel 11, located at the upper and lower edges of the front panel 11, respectively. Each panel of the front panel 11 is fixed to the front crossbeams 181 by screws. The corresponding independent panel can be removed by unscrewing the screws. Furthermore, front flanges 16 are provided on both sides of the front panel 11 to reinforce the connection between the front panel 11 and the side end panels 15. Handles 160 are provided on the front flanges 16.

[0061] The rear panel 12 is horizontally divided into several independent panels: a VAC board panel 121, a first CAP board panel 122, a first power board panel 123, a second CAP board panel 124, a second power board panel 125, a CRC absorption board panel 126, and an output sampling board panel 127. The VAC board panel 121 has a switch 1213 and a through-type high-current terminal block 1215. The output sampling board panel 127 has two 120A copper square terminals 1270. The first CAP board panel 122, the first power board panel 123, the second CAP board panel 124, the second power board panel 125, and the CRC absorption board panel 126 all have arrayed ventilation holes 1150 for heat dissipation. The inner wall of the rear panel 12 has two vertically arranged rear crossbeams 182, located at the upper and lower edges of the rear panel 12, respectively. The panels of the rear panel 12 are fixed to the rear crossbeams 182 by screws. The corresponding independent panel can be removed by unscrewing the corresponding screws. Rear flanges 17 are provided on both sides of the rear panel 12 to reinforce the connection between the rear panel 12 and the side end panels 15.

[0062] The upper panel 13, the lower panel 14, and the two side panels 15 are each integrally formed, and the panels are fixedly connected to each other by screws.

[0063] The chassis 10 also includes several central crossbeams and several guide rails. The guide rails are perpendicular to each crossbeam in pairs, forming a square frame for fixing the control module 40 and the functional module 50. The central crossbeams are divided into several first central crossbeams 183 and several second central crossbeams 184. The first central crossbeams 183 and the second central crossbeams 184 are arranged vertically, with the first central crossbeams 183 close to the front crossbeam 181 and the second central crossbeams 184 close to the rear crossbeam 182.

[0064] The first backplate 21 is positioned between the upper and lower first middle crossbeams 183, and the second backplate 22 is positioned between the upper and lower second middle crossbeams 184, with a certain distance between them. The first backplate 21 and the second backplate 22 form a first compartment 31, and the second backplate 21 and the second backplate 22 form a second compartment 32, which serves as the operating space for adjusting the wiring of the power supply device in this embodiment. The second backplate 22 and the rear panel 12 form a third compartment 33.

[0065] The guide rails are divided into several first guide rails 191 and several second guide rails 192. The first guide rails 191 are located in the first compartment 31 and are vertically erected between the front crossbeam 181 and the first middle crossbeam 183, forming several first frames for placing the control module 40 circuit boards. The second guide rails 192 are located in the third compartment 33 and are vertically erected between the rear crossbeam 182 and the second middle crossbeam 184, forming several second frames for placing the functional module 50 circuit boards.

[0066] The second back panel 22 facing the second compartment 32 is provided with several quick-connect terminals 24. Each functional module 50 is connected to the second back panel 22 through the quick-connect terminals 24. Each functional module 50 is functionally independent. The quick-connect terminals 24 are fixedly connected to the copper busbar 25 by screws. By adjusting the connection method of the copper busbar 25, the mode switching of different circuits and different polarity power supplies can be realized.

[0067] Specifically, the control module 40 is placed in the first compartment 31. The control module 40 includes a signal processing board 41, a control board 43, and an ADC acquisition board 45, which are fixed in the form of PCB boards and using a quick-connect installation method within several first frames. The signal processing board 41 corresponds to the signal processing board panel 112, the control board 43 corresponds to the control board panel 113, and the ADC acquisition board corresponds to the acquisition board panel 114. Each board of the control module 40 is inserted into the vertically positioned first guide rails 191 on its upper and lower sides, respectively. The other two sides of the board correspond to the first backplate 21 and the front panel 11, respectively. That is, the first guide rails 191 are perpendicular to each panel. When it is necessary to replace a board of the control module 40, simply loosen the screws, remove the corresponding independent panel, and pull the board out along the first guide rails 191. Other boards can then be inserted; this is the quick-connect installation method.

[0068] The signal processing board 41, control board 43, and ADC acquisition board 45 are interconnected via the first backplane 21. The ADC acquisition board 45 performs high-precision and high-speed acquisition of the key input and output signals of the power supply and sends them to the control board 43 for processing. The control board 43 outputs relevant control signals to control the overall operation of the power supply. The signal processing board 41 is used to handle the power supply's fault protection, fault interlocking, and protection and processing of some analog sampling signals. The first backplane 21 and the second backplane 22 are connected via a copper busbar 25 or a coaxial cable, enabling the control module 40 to connect with the functional module 50.

[0069] The accelerator magnet power supply has very high reliability requirements. The signal processing board 41 detects and judges all fault signals such as device over-temperature, over-voltage, over-current, and external interlock inputs. All of these are hardware-based protections, which implement protection functions through physical circuits. When abnormal conditions such as over-current or over-voltage occur, it can respond in a very short time, quickly cut off the circuit or take other protective measures. Furthermore, the design of this circuit is based on mature circuit design and physical principles and does not depend on the operation of software programs.

[0070] The control board 43 can perform calculation, processing and analysis of the overall power supply data, and can output control signals PWM. It has an embedded large-capacity serial-parallel FLASH, an isolated digital output interface, and preset timing that can meet the control needs of most magnet power supplies.

[0071] The function of the ADC acquisition board 45 is to convert continuously changing analog signals, such as voltage and current signals, into discrete digital signals. It samples the analog signals at a certain sampling frequency, converts them into digital signals, and stores them for analysis, processing, and display. The ADC acquisition board 45 can communicate directly with a host computer via a network port to display the acquired data in real time. It can also connect to the control board 43 to perform relevant processing and analysis on the acquired signals.

[0072] Specifically, the functional module 50 is placed in the third compartment 33. The functional module 50 includes a VAC board 51, two CAP boards 52, two power boards 53, two driver boards, a CRC absorption board 54, and an output sampling board 55. Each functional module 50 is fixedly placed in several second frames in the form of a PCB board using a quick-connect installation method.

[0073] The power board 53 and the driver board are combined to form a functional module 50. During system upgrades, the power board can be modified or replaced as needed. The two boards are connected via quick-connect pin headers and female headers to enhance isolation and prevent interference from the high-voltage, high-current signals in the power board 53 to the driver circuit, thus improving signal stability and reliability. Furthermore, both the power board 53 and the driver board are equipped with snap-fit ​​shields to independently shield these circuit components, enhancing system stability and anti-interference capabilities.

[0074] In this preferred embodiment, the VAC board 51, the first CAP board 52, the first power board 53 driving board, the second CAP board 52, the second power board 53 driving board, the CRC absorption board 54, and the output sampling board 55 are arranged sequentially, corresponding to the VAC board panel 121, the first CAP board panel 122, the first power board panel 123, the second CAP board panel 124, the second power board panel 125, the CRC absorption board panel 126, and the output sampling board panel 127, respectively. Each board of the functional module 50 is inserted into the upper and lower sides of the upper and lower second guide rails 192, respectively. The other two sides of the board correspond to the second backplate 22 and the rear panel 12, respectively. That is, the second guide rails 192 are perpendicular to each panel. When it is necessary to replace a board of the functional module 50, simply loosen the screws, remove the corresponding independent panel, and pull the board out along the second guide rail 192. Other boards can then be inserted, which is a quick-plug installation method.

[0075] Each functional module 50's board is connected to the second backplane 22 via several quick-connect terminals 24, and each functional module 50 is independent of the others. The quick-connect terminals 24 are fixed to copper busbars 25 with screws. By adjusting the connection method of the copper busbars 25, the connection between different functional modules 50 can be switched. The first backplane 21 and the second backplane 22 are connected to coaxial cables via ribbon cables. Both the ribbon cables and coaxial cables can be considered as formable quick interfaces, thereby enabling the connection between the control module 40 and the functional modules 50.

[0076] Specifically, the VAC board 51 enables the access of external AC power. A fuse holder facilitates fuse installation and replacement. An EMI filter filters the AC power. The filter is connected and fixed to the circuit board with screws and copper busbar 25 to increase overall stability. Mylar plates are added between the filter and the circuit board for insulation. The output of the filter is also connected to the PCB board using copper busbar 25. An AC-DC power module generates 24V control power, and the 24V control power and bus AC power are switched on and off through the panel switches, DC relays and AC relays.

[0077] In its functional design, the CAP 52 board utilizes the unidirectional conductivity of the diodes in the rectifier bridge to prevent reverse connection of the input bus DC power supply, followed by LC filtering to ensure the stability of the bus voltage. When the input power supply cannot meet the instantaneous energy demand of the subsequent circuits, the capacitors can release stored energy to supplement the power supply and ensure normal circuit operation. Simultaneously, a cooling fan control module 40 is added to the circuit so that the fan speed can change according to the temperature of the heatsink. The fan control module 40 detects the temperature of the heatsink, such as the power module's heatsink or the CAP 52 board's heatsink, to adjust the fan speed, ultimately improving the overall lifespan of the fan.

[0078] The CRC absorption board 54 design uses thin-film capacitors and power resistors. Functionally, it absorbs the resonant energy of voltage spikes generated during switching operation, preventing damage from excessively high voltage spikes. It also effectively reduces electromagnetic interference and improves the circuit's electromagnetic compatibility. The power module output is typically connected to an LC circuit, followed by an RC circuit in parallel. Because the power supply load is an inductor and resistor in series, and the load inductance is relatively high (i.e., a large time constant), coupled with the special requirements for ripple and high stability, the second-order stage of the subsequent high-frequency filter circuit becomes a challenge for PID correction. A voltage loop plus a current loop control mode is generally used, but this also introduces the problem of complex control parameter adjustments. In this design, adding an RC compensation branch at the power supply load end modifies the characteristics of the load. After adding the RC compensation branch, the power supply output phase frequency curve changes more gently at the crossover frequency and is further away from the 180° phase, which is more conducive to adjusting the control loop parameters. The L output of the power module is on the power board, while the C and RC circuits are on the CRC board.

[0079] The output sampling board 55 is functionally designed with one voltage sensor and two current sensors. One current sensor is used for feedback, and the other for sampling. The DCCT current sensor is mounted flat on the circuit board with screws. Mylar sheets are used for insulation between the DCCT and the circuit board, and copper busbars 25 are used for the intermediate wires. Furthermore, the power and signal lines of the DCCT are connected to the circuit board using DB9 connectors and ribbon cables. The DCCT power supply uses a low-ripple output LDO to provide a stable DC voltage to the sensor, reducing the impact of voltage fluctuations on the measurement results, thereby improving the accuracy of current measurement, reducing system failures caused by unstable sensor power supply, and improving the stability and reliability of the entire system. Copper busbars 25 are also used when connecting to the panel output terminals, and a ferrite core is fitted onto the busbar to effectively suppress common-mode interference signals. The output sampling board 55 mounts the DCCT onto the board, facilitating installation and, from an electrical structure perspective, avoiding signal line crossing issues, which is more conducive to improving the performance of the power supply unit.

[0080] The bus power module 60 includes several DC power supplies. The first backplate 21 does not completely separate the first compartment 31 and the second compartment 32; there is still a partial connection between the first compartment 31 and the second compartment 32. Several DC power supplies are placed horizontally across the first compartment 31 and the second compartment 32, and are located next to the control module 40. The lower panel 14 of the chassis 10 is provided with a slide rail and a third backplate 23. The bus power module 60 is fixed in the chassis 10 by the slide rail 62, and corresponds to the front ventilation panel 115. The slide rail 62 not only enables the plug-in installation of the bus power module 60, but also allows for the calibration of the installation position of the bus power module 60. This saves time and effort during installation and avoids the possibility of incorrect wiring. The third backplate 23 is located in the second compartment 32. The DC power supplies are connected to the third backplate 23 by several quick-connect terminals 24. The third backplate 23 and the second backplate 22 are connected by copper busbars 25, thereby enabling the bus power module 60 to be connected to the functional module 50.

[0081] In the above embodiments, the bus power module 60 is equipped with two DC power supplies. In other embodiments, depending on actual needs, only one DC power supply may be used, such as... Figure 12 As shown.

[0082] In the above embodiments, the bus power module 60 is suitable for a DC power supply with a quick-connect interface, allowing it to be installed next to the control module 40 for a compact design. In other embodiments, the bus power module 60 is suitable for a DC power supply without a quick-connect interface, typically larger in size and higher in power. Installing this DC power supply requires increasing the height of the chassis of this invention, and the DC power supply without a quick-connect structure is installed at the bottom of the chassis. This DC power supply is then connected to the second backplane 22 via a copper busbar 25 or a cable, thereby connecting the bus power module 60 to the functional module 50. Furthermore, it is also possible to choose to install one or two DC power sources depending on the actual situation, such as... Figure 13 As shown. By changing the parameters of the modules, the overall function and output parameters of the power supply can be changed. For example, by adjusting the parameters and quantity of the DC power supply, the overall output parameters of the power supply can be adjusted. The same applies to other modules.

[0092] Compared to existing technologies, the modular design of the particle accelerator coil / magnet power supply in this embodiment not only facilitates the upgrading and modification of the power supply system but also avoids the chaotic internal layout caused by traditional wiring. This allows for the creation of a rational ventilation system within the chassis, improving heat dissipation. Modularizing the control components, functional components, and power supply components expands the power supply's applicability. Different circuits and power supply polarities can be switched by changing the wiring pattern, and the overall function and output parameters of the power supply can be altered by changing the module parameters.

[0093] Moreover, the particle accelerator coil / magnet power supply device of this embodiment has undergone actual field assembly, maintenance, upgrade and modification, power supply operating temperature testing, power supply operation stability testing, and other tests, and the results are all superior to those of traditional integrated power supplies.
