[0018] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this application.

[0019] To address the problem of the lack of a means to quickly and accurately adjust the output voltage and the difficulty in providing a stable constant voltage in the existing technology.

[0020] This utility model provides an intelligent AC voltage stabilization power supply system. Please refer to [link / reference]. Figure 1 The power supply system consists of a voltage detector, a comparator, a linear amplifier, a switching amplifier, a linear regulator, a switching regulator, a controller, and an analog module, specifically including:

[0021] The voltage detector is connected to an AC power supply and a comparator, the comparator is connected to a linear amplifier and a switching amplifier, the linear amplifier is connected to a linear regulator, and the switching amplifier is connected to a switching regulator.

[0022] The other end of the linear regulator and the switching regulator is connected to the load;

[0023] The controller is connected to the analog voltage detector, the digital voltage detector, the linear amplifier, and the switching amplifier, and the analog quantity module is connected to the simulator.

[0024] The core of this application is a regulation mechanism that detects changes in input voltage and compensates for these changes by adjusting a portion of the output voltage. This regulation is achieved through the transformer's turns ratio, electronic switching, or a switching mechanism. The regulation process needs to be rapid and precise to ensure stable output voltage.

[0025] Furthermore, the analog module is a PLC, which is used to acquire the input voltage in real time, draw conclusions through an internal comparison program, and send adjustment commands to the controller.

[0026] The PLC with analog module acquires the input voltage in real time, draws a conclusion through internal comparison program, uses an amplifier to drive the regulation component, the power regulator component works, and controls the output voltage to be stable.

[0027] Voltage detection is the first crucial component in an AC voltage regulator circuit. Its main function is to monitor changes in the input voltage in real time and convert these changes into signals that can be processed by subsequent parts of the circuit. The principle of voltage detection is based on a comparator circuit. By setting a reference voltage, when the input voltage exceeds or falls below the reference voltage, the output state of the comparator changes, thereby triggering the circuit to perform corresponding adjustment actions.

[0028] Voltage detectors have a wide range of applications in circuits. They can be used not only in voltage regulation circuits but also in voltage monitoring, power management, and other applications. Their core function is to ensure the stability of power supply and prevent equipment damage or performance degradation caused by voltage fluctuations.

[0029] Furthermore, the voltage detector includes an analog voltage detector and a digital voltage detector.

[0030] Furthermore, the power supply system also includes an overcurrent protection circuit, an overvoltage protection circuit, and a short-circuit protection circuit, which are used to trigger protection actions, cut off the circuit, or limit the current when an abnormality is detected.

[0031] The comparator is one of the core components in a voltage regulator circuit. Its main function is to compare the output signal of the voltage detector with a reference voltage and generate a corresponding digital signal. This digital signal is typically used to control the operating state of the power regulation component to maintain a stable output voltage.

[0032] Furthermore, the comparator is used to compare the output signal of the voltage detector with the reference voltage and generate a corresponding digital signal; the digital signal is used to control the operating state of the power regulation component to maintain a stable output voltage.

[0033] Factors to consider when designing comparator circuits include: input bias current (an ideal comparator should have the lowest possible input bias current); response speed (the comparator's response speed determines the circuit's reaction time to voltage changes); output drive capability (the comparator's output signal needs to be capable of driving subsequent circuits); and a higher power supply rejection ratio (PSRR), which indicates a stronger ability of the comparator to suppress power supply noise.

[0034] Furthermore, the amplifier is used to amplify the control signal generated by the comparator to control the power conditioning components, and the amplifier includes a linear amplifier and a switching amplifier.

[0035] Amplifiers play a crucial role in AC voltage regulator circuits. Their primary function is to amplify the control signal generated by the comparator, providing sufficient current and voltage drive capability to control the power regulation components. Furthermore, amplifiers can also be used to adjust the circuit's response speed and stability.

[0036] Furthermore, the power regulation component is used to adjust the output voltage according to the control signal of the amplifier, and the power regulation component includes a linear regulator and a switching regulator.

[0037] The power regulation component is a key part of the AC voltage regulator circuit. Its function is to adjust the output voltage according to the amplifier's control signal. Common power regulation components include linear regulators and switching regulators (such as Buck, Boost, and Buck-Boost converters).

[0038] Furthermore, the switch regulator includes a Buck converter, a Boost converter, and a Buck-Boost converter.

[0039] The design should adhere to the principles of high accuracy, good stability, and fast response. For monitoring, analog voltage detectors and digital voltage detectors should be selected based on the scenario and requirements, with different choices for different environments. When wiring, strong and weak currents should be separated, and monitoring lines should be kept away from power lines as much as possible to avoid magnetic field interference.

[0040] In this application, the generation of the reference voltage and the processing of the comparator output are crucial steps in ensuring voltage regulation accuracy and response speed. First, the method for generating the reference voltage and its stability implementation techniques are discussed. Then, the amplification, shaping, filtering, and stability analysis of the comparator output are analyzed. The reference voltage is a reference value in the circuit used to compare with the detected input voltage, thereby driving the power regulation component to perform voltage regulation. The accuracy and stability of the reference voltage (built-in reference voltage source and external reference voltage source) directly affect the performance of the voltage regulator.

[0041] In this embodiment of the utility model, safety and protection measures also need to be considered. Corresponding protection circuits need to be designed, such as overcurrent protection, overvoltage protection, short circuit protection and insulation protection, to prevent excessive current from damaging components, to prevent excessive voltage from burning out the load, to avoid excessive current during short circuits, and to ensure that the high-voltage part in the circuit has sufficient insulation from other parts.

[0042] In addition, the embodiments of this utility model also have certain environmental adaptability: temperature adaptability, humidity adaptability, and vibration adaptability.

[0043] Components suitable for operation within the target temperature range should be selected, and a protective coating should be applied to the circuit board surface to prevent short circuits caused by moisture. Vibration factors should be considered during the design process, and circuit connections should be secure. The voltage regulator should also be maintained and inspected regularly, and outdated components should be replaced in a timely manner.

It is not intended to be exhaustive or to limit the invention to a single disclosed embodiment. As mentioned above, various alternatives and variations of this application will be apparent to those skilled in the art to which the foregoing pertains.
