Figure 6 This is a schematic diagram of a process for testing a first output voltage according to an embodiment, such as... Figure 6 As shown, in the process of predicting the first output voltage of the voltage regulator, the host computer system includes a PC (Personal Computer System). The system uses a PC (personal computer) and serial communication to detect the second output voltage after the actual first output voltage of the voltage regulator is detected by the detection circuit. The PC also retrieves the first detected voltage corresponding to the second output voltage from a target relationship set and predicts the first output voltage of the voltage regulator based on the first detected voltage. The photoelectric conversion circuit includes a microcontroller, a feedback circuit, and an AD acquisition unit. The microcontroller sends the acquired electrical signal (second output voltage) to the host computer system for processing via serial communication. The near-infrared light working system includes a point-contact detection probe, a near-infrared light source driving circuit, a chromophore solution (target solution), and a near-infrared light junction circuit. The point-contact detection probe connects to the detection point in the circuit under test and receives the actual first output voltage of the voltage regulator. The circuit under test is an immersion liquid-cooled server. The first output voltage is transmitted to the near-infrared light source driving circuit through the resistor in the point-contact detection probe. The near-infrared light source driving circuit converts electrical energy into light energy, inputs the chromophore solution, and outputs the light from the chromophore solution. This light is then incident on the near-infrared light junction circuit and converted into an electrical signal, i.e., the second output voltage, by the AD acquisition and feedback circuit in the photoelectric conversion circuit.

[0084] The photoelectric conversion circuit converts the optical signal into an electrical signal and reports the signal strength of the electrical signal to the host computer system. The host computer system predicts the first output voltage of the voltage regulator through the target relationship set.

Figure 7 This is a flowchart of a process for testing a first output voltage according to an embodiment, such as... Figure 7 As shown, first locate the test point in the immersion liquid-cooled server, and connect the point-type detection probes to the copper foil of the test point and the ground wire respectively. The near-infrared light source driving circuit outputs near-infrared light of different intensities based on the voltage value detected by the probes. The chromophore solution absorbs some of the near-infrared light with wavelengths of 760nm to 850nm. The near-infrared light receiving circuit converts the received near-infrared light intensity into an electrical signal and transmits it to the acquisition circuit. The acquisition chip transmits the electrical signal to the feedback circuit, which then enters the microcontroller. The microcontroller then communicates with the host computer via a serial port. According to Beer-Lambert's law, the incident light intensity can be calculated from the received light intensity, and the voltage value of the test point can then be directly calculated in the host computer.
