Problems solved by technology

However, the above-mentioned protection mechanisms usually just shut down the power system without locking the power system
Users often restart the machine intuitively without knowing it. This restarting action may cause the damaged components to catch fire or smoke, which will pose a hidden danger to the safety performance of the electronic product.

Embodiment Construction

[0019] See figure 1 , the power supply system 100 of the present invention includes a power supply 110 , a plurality of circuit units 120 and a timing control circuit 130 .

[0020] The power supply 110 is connected to an external power supply. The power supply 110 usually includes an AC-DC converter for converting external commercial AC power into DC power for supplying power to the subsequent circuit unit 120 . The power supply 110 may further include a control terminal 111 , which is connected to the timing control circuit 130 and records the abnormal state of the circuit unit 120 .

[0021] The plurality of circuit units 120 may be a memory, a CPU, a hard disk, or a South Bridge or North Bridge circuit of a mainboard.

[0022] The timing control circuit 130 is connected between the power supply 110 and the plurality of circuit units 120 , and is used to respectively control the power supply 110 to supply power to the plurality of circuit units 120 in sequence. The timing...

Abstract

A power supply system includes a power supply, a timing control circuit and a plurality of circuit units. The power supply supplies power to the plurality of circuit units through the timing control circuit. When any circuit unit is abnormal, the timing control circuit will record the occurrence of the abnormal state, and shut down and lock the power supply so that the power supply cannot supply power to the multiple circuit units again. Therefore, the user cannot restart the device through normal operation, thereby preventing the damaged components from catching fire or emitting smoke, and causing hidden dangers to the safety performance of the electronic product.

Description

technical field [0001] The invention relates to a power supply system, in particular to a power supply system with automatic protection function. Background technique [0002] The power supply is the source of power for electronic products. With the development of technology, the integration density of electronic products is getting higher and higher, and multiple circuit units are usually integrated in the same system. For example, a computer system generally includes circuit units such as a CPU, a hard disk, and a memory, and the power supply supplies power to the multiple circuit units. The circuit units generally have a protection mechanism, and the protection mechanism will send a signal to the power system to shut down the power system when any circuit unit fails. However, the above-mentioned protection mechanism usually just shuts down the power system without locking the power system. Without the user's knowledge, the user often restarts the machine intuitively. T...
