Problems solved by technology
[0002] In the current information age, there are generally multiple DC (Direct Current, DC) power supplies inside servers, computers, or industrial equipment, which are used to convert the DC voltage output by the Power Supply Unit (PSU) into a DC voltage of the target size , internal DC power supply and high-value components may appear during debugging, handling and long-term use, such as central processing unit (Central Processing Unit, CPU), integrated south bridge (Platform Controller Hub, PCH), dual in-line memory module ( Damage to Dual Inline Memory Modules (DIMM), power chip (Integrated Circuit, IC), etc., resulting in a short circuit of the output of the DC power supply
[0003] At present, there is no automatic detection scheme for the short-circuit detection of the output impedance of the DC power supply unit. If the power is turned on without detection, once the output of the DC power supply unit is short-circuited, it is very likely to burn out the main board and high-value components, resulting in unnecessary Necessary loss

The invention provides a power supply short circuit detector and equipment. The detector comprises a power supply unit PSU, a DC power supply unit, a short circuit detection module and an informationprompt module; the PSU is connected with the DC power supply unit, a standby power supply port of the PSU and the DC power supply unit are connected with the short circuit detection module, the shortcircuit detection module outputs a prompt signal according to output impedance of the DC power supply unit, the short circuit detection unit is connected with the information prompt module, and the information prompt module prompts whether output of the DC power supply is shorted according to the prompt signal. Thus, whether the DC power supply unit is shorted is detected automatically, the detection efficiency is improved, the circuit stability is improved, and blind power-on under the condition of short circuit of the DC power supply unit and damage on other devices are avoided.
