Description

Technical Field

[0001] This invention relates to the field of power supply circuit technology, and more specifically to a remotely programmable power supply output reference control power supply output circuit structure. Background Technology

[0002] In existing technologies, voltage regulation circuits generally employ analog methods, adjusting the reference pin level of the voltage regulator control IC by adjusting the linear variable resistor on the hardware. The change in the reference pin level causes a change in the transmission current of the isolation optocoupler. After being isolated and transmitted, this current signal acts on the control chip in the form of negative feedback, adjusting the reference threshold of its internal comparator, thereby causing a corresponding change in the PWM duty cycle output by the control chip, thus achieving the purpose of changing the output voltage.

[0003] like Figure 1 As shown, RV1 is a linear variable resistor, internally composed of resistance wire. Its working principle is as follows: by changing the effective length of the resistance wire connected to the circuit, the resistance value is changed. Adjusting the knob on RV1 changes its resistance value, thereby changing the voltage level of the reference pin U2. The corresponding output voltage Vout also changes linearly, realizing hardware voltage regulation. The problem with this method is that the voltage regulation accuracy depends on the internal structure of the linear variable resistor and the material of the resistance wire, which has certain material deviation characteristics. This results in the output voltage accuracy not reaching the millisecond level, thus failing to meet the high-precision output voltage requirements of Industry 4.0 equipment. Summary of the Invention

[0004] In view of the deficiencies in the existing technology, the purpose of this invention is to provide a remotely controlled programmable power output reference control power output circuit structure that can remotely control the output voltage.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0006] This application provides a remote programmable power output reference control power output circuit structure, including a digital controller, an MCU chip, and a voltage output circuit. The digital controller is communicatively connected to the MCU chip and is used to convert external signals into electronic signals and transmit them to the MCU chip. The MCU chip is electrically connected to the voltage output circuit.

[0007] Furthermore, the MCU chip is connected to the digital controller via a standard communication interface.

[0008] Furthermore, the MCU chip is connected to the voltage output circuit by outputting a PWM square wave.

[0009] Furthermore, a resistor R41 and a capacitor C44 are connected in series on the general-purpose input and output pins of the MCU chip.

[0010] The beneficial effects of this invention are as follows:

[0011] This invention employs the aforementioned remote programmable power output reference control power output circuit structure. External signals are converted into digital signals by a digital controller, and the digital signals are converted into analog signals by an MCU chip and output as square waves to adjust the reference pin voltage. The reference pin follows the linear change to adjust the output voltage change, thereby achieving the purpose of remotely controlling the output voltage.

[0012] The remote programmable power output reference control power output circuit structure of the present invention uses the PWM output of a digital chip to replace the traditional linear variable resistor to adjust the reference voltage of the voltage regulator chip. In application, this control method only needs to be remotely controlled through communication function or automatically given voltage adjustment command by the device AI technology to achieve the adjustment of output voltage. Moreover, this digital control PWM method does not rely on the precision of traditional components. The output precision can be adjusted to the mV level digitally to meet the precise requirements of the device for power supply voltage. Attached Figure Description

[0016] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0017] Reference Figures 2 to 3 As shown, this embodiment provides a remote programmable power output reference control power output circuit structure, including a digital controller U9, an MCU chip, and a voltage output circuit.

[0018] In this embodiment, the digital controller U9 is communicatively connected to the MCU chip. External command signals are input to the digital controller, converted into digital signals by the digital controller U9, and then input to the MCU chip. The MCU chip processes the input digital signals and converts them into analog signals. The output terminal of the MCU chip is connected to a voltage output circuit, which outputs the converted analog signal to the voltage output circuit. This voltage output circuit adjusts the reference pin voltage (e.g., by outputting a PWM square wave), causing the reference pin to linearly change and adjust the output voltage to obtain the desired output voltage value.

[0019] In this solution, the user only needs to input the desired voltage remotely via a control device such as a computer or mobile phone. The entire process requires no on-site manual operation. Alternatively, the device can automatically generate a voltage adjustment command based on its own needs using AI algorithms, which is then sent to the MCU. The MCU can then precisely adjust the power output voltage using this method. This voltage adjustment method offers high accuracy and speed, significantly improving work efficiency and avoiding the costs and safety hazards of on-site personnel. It achieves a deeper level of fully automated, unattended operation.

[0020] In some embodiments, in order to be easily integrated into industrial automation systems, IoT platforms, and laboratory automation systems, the MCU chip communicates with the digital controller through standard communication interfaces, such as the IIC (Inter-Integrated Circuit) interface and the CAN (Controller Area Network) interface.

[0021] In some embodiments, a resistor R41 and a capacitor C44 are connected in series on the general-purpose input and output pins of the MCU chip. The resistor R41 serves as a current limiting protection to prevent excessive current in the circuit from damaging the pins of the MCU chip. The added capacitor C44, together with the resistor R41, can also filter out high-frequency noise, and together they function as a low-pass filter.

[0022] The remote programmable power supply output reference control circuit structure of this invention deeply integrates traditional analog power supply control technology with modern digital power supply control technology and network communication technology, completely changing the way power supplies are used and managed. The power supply is no longer just a simple energy conversion device, but an intelligent node integrating precise power supply, intelligent control, status monitoring, and data acquisition. It is an indispensable basic tool in Industry 4.0, automated testing, scientific research, and fully automated unattended operation applications.

[0023] The core value of the remote programmable power output reference control circuit structure of this invention lies in its controllability, programmability, integrability, and datafication. Typical application scenarios include automated testing systems, semiconductor aging and life testing systems, remote and unattended facilities and equipment, photovoltaic / cell simulation and testing, and aerospace and military equipment, all of which have a significant impact. It can adapt to various complex environments and applications through precise AI control based on changes in the usage environment. This solves the industry pain points of the early analog era, such as the need for on-site operation, low work efficiency, and potential personnel safety hazards.

[0024] The remote programmable power output reference control power output circuit structure of this invention effectively and efficiently realizes the function of remote control. It can be controlled manually or automatically and accurately by AI according to environmental application requirements, ultimately achieving the goal of intelligent power supply to meet the application needs of equipment. Moreover, this accuracy reaches an amazing mV level voltage, which has excellent performance in fields such as medical, semiconductor manufacturing equipment and aerospace. It is an indispensable core technology in fully automated applications with no human intervention and no human operation. It is deeply integrated into the development and application of Industry 4.0, greatly reducing human activity and contributing to the reduction of carbon emissions.
