Description

Technical Field

[0001] The invention belongs to the technical field of power supply, and in particular relates to a radio frequency ion source transient response power supply control system. Background Art

[0002] A power supply is a device that converts other forms of energy into electrical energy. The main function of a power supply is to provide electrical energy to a circuit. Depending on the conversion method, power supplies are mainly divided into two categories: DC power supplies and AC power supplies. DC power supplies output current and voltage in a constant direction, which are commonly found in batteries, DC regulated power supplies, etc., while AC power supplies output current and voltage that change periodically, such as household mains electricity.

[0003] The existing RF ion source and Hall ion source power supply systems respond slowly when faced with transient load impacts, which may cause power supply damage or instability in the power supply system. In particular, current overshoot and voltage rebound problems are prone to occur when the power supply system is started or shut down, making it impossible to ensure the stability of the power supply and the power supply system. Therefore, an RF ion source transient response power supply control system is needed to solve the above problems. Summary of the invention

[0004] The object of the present invention is to provide a radio frequency ion source transient response power supply control system to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical scheme: a radio frequency ion source transient response power supply control system, comprising an MCU controller and a protection circuit module, wherein the MCU controller is connected to a digital controller, the MCU controller is connected to a PID control algorithm, the MCU controller is connected to a power main chip, the power main chip is connected to an ion source, the power main chip is connected to feedback monitoring, the feedback monitoring is connected to the MCU controller, the MCU controller is connected to a switching frequency adjustment module, the switching frequency adjustment module is connected to the power main chip, and the protection circuit module is connected to the power main chip.

[0006] By setting the above structure, feedback monitoring can accurately collect the current, voltage and other parameters of the power supply output in real time, and quickly feed back to the MCU controller. The digital controller in the MCU controller can coordinate the work of each module, and its built-in PID control algorithm can accurately calculate the output deviation according to the feedback information, and then generate a suitable control signal. Under the action of the control signal, the power supply main chip can quickly adjust the output waveform to adapt to the sharp change of the load, ensuring that when the load changes drastically, the power supply can respond quickly and maintain stable output. The switching frequency adjustment module can flexibly change the switching frequency of the power supply main chip according to the instructions transmitted by the MCU controller, thereby further optimizing the power supply. The protection circuit module can monitor the working status of the power supply main chip in real time. Once abnormal conditions such as overvoltage, overcurrent, and overheating are detected, the protection circuit module can immediately start the protection mechanism to adjust the power supply, thereby avoiding the power supply components from being damaged by load impact as much as possible. With the mutual cooperation of various modules, the power supply can make a smooth transition during the startup and shutdown process, and can effectively reduce the fluctuation of current and voltage, comprehensively improve the stability and reliability of the power control system, thereby significantly extending the service life of the power supply and the entire power control system, and also improving the transient response capability of the power supply.

[0007] As a preferred solution, the MCU controller includes a digital controller and a PID control algorithm, and the MCU controller can adjust the output of the power supply in real time through the digital controller and the PID control algorithm.

[0010] As a preferred solution, the power main chip is the core power device of the power control system, which is responsible for converting input electrical energy into output electrical energy that meets the requirements.

[0011] As a preferred solution, the ion source is the load of the entire system. Under the action of the electric energy provided by the power main chip, it generates physical phenomena such as ion beams and is used in experiments requiring ions.

[0012] As a preferred solution, the feedback monitoring can monitor the output voltage and current of the power main chip in real time, and can feed back these actual values ​​to the MCU controller so that the MCU controller can understand the working status of the power main chip.

[0013] As a preferred solution, the switching frequency adjustment module can adjust the output characteristics of the power supply by changing the switching frequency of the power supply main chip, and can optimize the conversion efficiency and dynamic response performance of the power supply.

[0014] As a preferred solution, the protection circuit module can protect the power control system from overvoltage, overcurrent and overheating. When an abnormal situation occurs in the power control system, the protection circuit module can quickly adjust the power supply to prevent damage to the power main chip and other components.

[0015] By setting up feedback monitoring and switching frequency adjustment modules, feedback monitoring can not only provide real-time output parameter feedback for the MCU controller, but also analyze the monitored data. When it detects that certain parameters are out of the normal range, it can issue a fault warning signal in advance to remind operators to check and deal with it in time, so as to avoid further expansion of the fault; the switching frequency adjustment module can not only improve the transient response capability of the power supply, but also adjust the switching frequency according to the size and characteristics of the load to optimize the conversion efficiency of the power supply, thereby improving the efficiency of the entire power control system.
