Description

Technical Field

[0001] The invention relates to the technical field of computer power supply detection, in particular to a testing device and method based on computer power supply. Background Art

[0002] Electronic computers, commonly known as computers, are modern electronic computing machines used for high-speed computing. They can perform numerical and logical calculations, have storage and memory functions, can run according to programs, and automatically and quickly process massive amounts of data. It consists of a hardware system and a software system. A computer without any software installed is called a bare metal. Computers are used as control systems for various industrial and consumer devices, including simple special-purpose equipment, industrial equipment, and general-purpose equipment. A computer power supply is a computer component installed inside a computer that is responsible for converting ordinary city electricity into a voltage that can be used by the computer. The computer power supply is a switching circuit that converts ordinary AC power into DC power, and then outputs different voltages to computer components such as the motherboard, hard disk, and optical drive by chopping the voltage. The switching power supply mainly includes an input grid filter, an input rectifier filter, a converter, an output rectifier filter, a control circuit, and a protection circuit. Their functions are: the input grid filter eliminates interference from the power grid, such as the start-up of the motor, the switching of the electrical appliance, and lightning strikes, and also prevents the high-frequency noise generated by the switching power supply from spreading to the power grid. The input rectifier filter rectifies and filters the input voltage of the power grid to provide a DC voltage for the converter. The converter is a key part of the switching power supply. It converts the DC voltage into a high-frequency AC voltage and isolates the output part from the input power grid. The output rectifier filter rectifies and filters the high-frequency AC voltage output by the converter to obtain the required DC voltage, while also preventing high-frequency noise from interfering with the load. The control circuit detects the output DC voltage, compares it with the reference voltage, and amplifies it. The pulse width of the oscillator is modulated to control the converter to maintain the stability of the output voltage.

[0003] The existing computer host may fail to start up during use. Because there is no professional testing equipment for detection, the power failure needs to be repaired outside, which incurs expenses. In addition, there are many power supplies of different specifications and sizes in the power supply production line, which makes it impossible to test different power supplies at the same time.
