Description

Technical Field

[0001] This utility model relates to the field of supercapacitor technology, specifically to a high-voltage pulse power supply based on a combination of supercapacitors and thin-film capacitors. Background Technology

[0002] With the increasing application of supercapacitors in various fields such as medical equipment, industry, military, and high-power pulse welding, the conventional approach of using single-cell energy storage devices is no longer suitable for certain application scenarios in these typical fields. From the perspective of instantaneous energy, only thin-film capacitors can currently meet the requirements; from the perspective of sustained capacity, only supercapacitors and batteries can currently meet the requirements; and from the perspective of lifespan and safety, only supercapacitors can currently meet the requirements.

[0003] For these specific application scenarios, how can we ensure both instantaneous energy requirements and continuous capacity requirements? In previous projects, we tried using energy storage devices with different characteristics, such as supercapacitors, electrolytic capacitors, and film capacitors, in different ways. However, the actual results were not ideal. Often, film capacitors did not fully utilize their high-frequency characteristics, while supercapacitors suffered from excessive transient losses, and electrolytic capacitors experienced bottlenecks in pin current, resulting in various imbalances. Utility Model Content

[0004] The purpose of this invention is to provide a high-voltage pulse power supply based on a combination of supercapacitors and thin-film capacitors, in order to solve the technical problems in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A high-voltage pulse power supply based on a combination of supercapacitors and thin-film capacitors includes: a DSP signal processing and control circuit, a human-machine interaction module, a communication and external control input circuit, an AC mains input and common-mode filtering module, an isolated supercapacitor energy injection system, a medium-voltage supercapacitor energy storage unit, a non-isolated boost circuit, a high-frequency filtering circuit, a high-voltage thin-film capacitor energy storage unit, an output high-voltage electronic switch, an isolation drive circuit, a multi-point voltage and current detection circuit, and a system power supply module;

[0007] The input terminal of the AC mains input and common-mode filter module is connected to the AC mains power supply, and its output terminal is connected to the system power supply module and the isolated supercapacitor power injection system, respectively.

[0008] The system power module is used to convert mains power into the operating voltage required by each sub-functional module of the system;

[0009] The isolated supercapacitor energy injection system is connected to the medium-voltage supercapacitor energy storage unit and is used to charge the medium-voltage supercapacitor energy storage unit according to a predetermined charging curve based on the characteristics of the supercapacitor, and to monitor its health status.

[0010] The medium-voltage supercapacitor energy storage unit is connected to the input terminal of the non-isolated boost circuit;

[0011] The output terminal of the non-isolated boost circuit is connected to the input terminal of the high-frequency filter circuit;

[0012] The output terminal of the high-frequency filter circuit is connected to the high-voltage thin-film capacitor energy storage unit.

[0013] The high-voltage thin-film capacitor energy storage unit is connected to the input terminal of the output high-voltage electronic switch;

[0014] The control terminal of the output high-voltage electronic switch is connected to the DSP signal processing and control circuit through the isolation drive circuit.

[0015] The DSP signal processing and control circuit is used to generate a PWM control signal based on the parameters set by the human-machine interaction module or the communication and external control input circuit, and drive the output high-voltage electronic switch to switch on and off through the isolation drive circuit.

[0016] The multi-point voltage and current detection circuit is connected to the medium-voltage supercapacitor energy storage unit, the non-isolated boost circuit, and the high-frequency filter circuit, respectively, for collecting voltage and current signals and sending the processed signals to the DSP signal processing and control circuit.

[0017] This application combines supercapacitors (balancing capacity and lifespan) and thin-film capacitors (balancing instantaneous energy) via a non-isolated boost circuit, and precisely controls them using DSP signal processing and control circuitry. This achieves segmented optimized energy management, simultaneously meeting the dual requirements of high-voltage pulse output for both instantaneous high power and continuous power supply, overcoming the "imbalance phenomenon" caused by simply mixing different energy storage devices in prior art. Systematic voltage and current detection and health status monitoring further enhance the system's safety and reliability.

[0018] In some possible embodiments, the DSP signal processing and control circuit uses a DSP signal processing and control circuit, a microcontroller, or an FPGA as the core processing chip. Using a programmable digital signal processing chip as the control core has the advantages of enabling complex and flexible control algorithms (such as custom charging curves and PWM generation algorithms), high processing speed, high control precision, and facilitating intelligent system management and parameter adjustment.

[0019] In some possible embodiments, the human-machine interaction module uses a configuration screen, digital tube display, or traditional LCD screen to realize human-machine interaction functions. It provides users with an intuitive and convenient interface for parameter setting and status monitoring, enhancing the product's ease of use and operability, and is particularly suitable for application scenarios requiring on-site debugging and parameter modification.

[0020] In some possible embodiments, the communication and external control input circuit supports CAN, RS485, or RS232 communication methods and employs opto-isolated level control input. Providing multiple standard communication interfaces and using opto-isolation allows this pulse power supply to be easily integrated into larger automated control systems (such as host control systems), enabling remote control and online operation. Opto-isolation effectively suppresses ground loop interference and signal noise caused by potential differences, improving communication reliability and anti-interference capability.

[0021] In some possible embodiments, the AC mains input and common-mode filtering module uses a common-mode inductor wound with ferrite or iron-silicon-aluminum materials for filtering. This effectively filters out common-mode interference from the mains power grid, prevents external electromagnetic interference from entering the system, and also suppresses high-frequency noise generated by the system from feeding back to the power grid, improving the system's electromagnetic compatibility (EMC) performance and ensuring the stable operation of subsequent circuits.

[0022] In some possible embodiments, the isolated supercapacitor power supply system can be replaced by a conventional constant current and constant voltage universal charger.

[0023] In some possible embodiments, the medium-voltage supercapacitor energy storage unit uses electric double-layer supercapacitors, lithium-ion capacitors, or batteries as energy storage devices. This provides multiple optional implementation methods for the medium-voltage energy storage unit, increasing design flexibility. In particular, using electric double-layer supercapacitors or lithium-ion capacitors can fully leverage their advantages of long cycle life, high power density, and good safety, meeting the system's long-term reliable operation requirements for front-end energy storage.

[0024] In some possible embodiments, the non-isolated boost circuit employs either a non-isolated BOOST boost circuit or a high-frequency transformer isolated boost circuit. This provides two efficient boost solutions. The BOOST circuit topology is simple and highly efficient; while the high-frequency transformer isolation solution achieves electrical isolation, enhancing system safety. Depending on the specific efficiency and isolation requirements of the application, a flexible choice can be made to optimize system performance.

[0025] In some possible embodiments, the high-frequency filtering circuit employs an electrolytic capacitor, a film capacitor, or an LC or CLC filter circuit composed of an inductor. This effectively filters out high-frequency pulse components and ripple generated by the switching action of the boost circuit, smooths the boosted voltage, and provides a stable and clean DC voltage for the subsequent high-voltage film capacitor, ensuring the quality and stability of the output pulse.

[0026] In some possible embodiments, the high-voltage thin-film capacitor energy storage unit is constructed using series, parallel, or series-parallel combinations of thin-film capacitors. Through flexible series-parallel combinations, the voltage rating and total capacity of the energy storage unit can be easily expanded to meet the specific pulse voltage and energy requirements of different projects, improving the product's customizability and adaptability.

[0027] In some possible embodiments, the output high-voltage electronic switch employs high-voltage transistors, high-voltage IGBTs, high-voltage MOSFETs, or silicon carbide MOSFETs. This provides a variety of high-performance switching device options. In particular, the use of silicon carbide MOSFETs offers advantages such as fast switching speed, high temperature resistance, and low conduction losses, significantly improving the frequency and accuracy of pulse output, reducing switching losses, and enhancing overall system efficiency.

[0028] In some possible embodiments, the isolation drive circuit employs optical isolation or magnetic isolation drive methods.

[0029] In some possible embodiments, the multi-point voltage and current detection circuit employs resistance sampling, Hall-isolated sampling, or optical / magnetic isolation integrated circuit sampling.

[0030] In some possible embodiments, the system power module is implemented using a high-frequency switching power supply, a power frequency transformer with rectifier and filter circuit, or an isolation step-down module.

[0031] In some possible embodiments, the DSP signal processing and control circuit preferably uses the TMS320F280025 as the core processing chip.

[0032] This utility model has the following beneficial effects:

[0033] 1. Supercapacitors, electrolytic capacitors, and film capacitors, through combinations of different voltages and locations, allow each segment to exert its own strengths, avoiding the contradictory phenomena found in simple mixed systems.

[0034] 2. Due to the introduction of an isolated supercapacitor energy injection system, the charging curve of the medium-voltage supercapacitor energy storage unit is more reasonable, and the actual capacity and internal resistance of the medium-voltage supercapacitor energy storage unit can be monitored during the process to analyze the health status of the supercapacitor, thereby improving the safety of the entire system.

[0035] 3. Due to the adoption of silicon carbide electronic switches, its real-time performance is further improved, and the applicable pulse frequency is broadened. Attached Figure Description

It is worth noting that the following embodiments are merely illustrative of this application and do not constitute a limitation thereof.

[0043] Example 1:

[0044] like Figure 1 As shown, this utility model discloses a high-voltage pulse power supply based on a combination of supercapacitors and thin-film capacitors, including: a DSP signal processing and control circuit, a human-machine interaction module, a communication and external control input circuit, an AC mains input and common-mode filtering module, an isolated supercapacitor energy injection system, a medium-voltage supercapacitor energy storage unit, a non-isolated boost circuit, a high-frequency filtering circuit, a high-voltage thin-film capacitor energy storage unit, an output high-voltage electronic switch, an isolation drive circuit, a multi-point voltage and current detection circuit, and a system power supply module;

[0045] The input terminal of the AC mains input and common-mode filter module is connected to the AC mains power supply, and its output terminal is connected to the system power supply module and the isolated supercapacitor power injection system, respectively.

[0046] The system power module is used to convert mains power into the operating voltage required by each sub-functional module of the system;

[0047] The isolated supercapacitor energy injection system is connected to the medium-voltage supercapacitor energy storage unit and is used to charge the medium-voltage supercapacitor energy storage unit according to a predetermined charging curve based on the characteristics of the supercapacitor, and to monitor its health status.

[0048] The medium-voltage supercapacitor energy storage unit is connected to the input terminal of the non-isolated boost circuit;

[0049] The output terminal of the non-isolated boost circuit is connected to the input terminal of the high-frequency filter circuit;

[0050] The output terminal of the high-frequency filter circuit is connected to the high-voltage thin-film capacitor energy storage unit.

[0051] The high-voltage thin-film capacitor energy storage unit is connected to the input terminal of the output high-voltage electronic switch;

[0052] The control terminal of the output high-voltage electronic switch is connected to the DSP signal processing and control circuit through the isolation drive circuit.

[0053] The DSP signal processing and control circuit is used to generate PWM control signals based on the parameters set by the human-machine interaction module or the communication and external control input circuit, and drive the output high-voltage electronic switch to switch on and off through the isolation drive circuit. As the core part of the system's digital signal processing, the DSP signal processing and control circuit works with the program to complete the logic control and data analysis of the whole machine.

[0054] The multi-point voltage and current detection circuit is connected to the medium-voltage supercapacitor energy storage unit, the non-isolated boost circuit, and the high-frequency filter circuit, respectively, for collecting voltage and current signals and sending the processed signals to the DSP signal processing and control circuit.

[0055] The AC mains power (single-phase or three-phase, depending on the specific system power) is input and then filtered by common-mode filtering. On one hand, it is sent to the system power module, where it is converted into different voltages required for the normal operation of each sub-functional module of the system. On the other hand, it is sent to the isolated supercapacitor energy injection system, which charges the medium-voltage supercapacitor energy storage unit according to the agreed charging curve based on the characteristics of the matched supercapacitor, and evaluates the current health status of the medium-voltage supercapacitor energy storage unit. Here, medium voltage is relative to the high voltage of the subsequent film capacitor. The specific configuration voltage and capacity need to be determined according to the voltage and capacity requirements of the specific project.

[0056] Once the voltage of the medium-voltage supercapacitor energy storage unit reaches the minimum operating voltage requirement, the system activates the non-isolated boost circuit to boost the medium-voltage supercapacitor energy storage unit to the system output set voltage in a maximum-efficiency manner. Then, the pulse components generated by the boost circuit are filtered out by a high-frequency filter circuit composed of electrolytic capacitors. Finally, the high voltage to be output is stored in the high-voltage film capacitor energy storage unit.

[0057] Based on the parameter settings of the human-machine interface module, such as frequency and output time, or the real-time parameters issued by the upper control system, the local DSP signal processing and control circuit generates corresponding PWM control signals according to the pre-designed algorithm. These signals effectively drive the output electronic switch to open and close according to a predetermined pattern through the isolation drive circuit, thereby achieving the overall output effect of the high-voltage pulse power supply.

[0058] This application combines supercapacitors (balancing capacity and lifespan) and thin-film capacitors (balancing instantaneous energy) via a non-isolated boost circuit, and precisely controls them using DSP signal processing and control circuitry. This achieves segmented optimized energy management, simultaneously meeting the dual requirements of high-voltage pulse output for both instantaneous high power and continuous power supply, overcoming the "imbalance phenomenon" caused by simply mixing different energy storage devices in prior art. Systematic voltage and current detection and health status monitoring further enhance the system's safety and reliability.
