Embodiment Construction

[0021] Detailed description and technical content of the present invention, now just explain as follows with respect to matching drawing:

[0022] see figure 1 , the method of the present invention to avoid multiple restarts of the power supply. The power supply 1 can be a commercial power supply, an industrial power supply or a redundant power supply, etc., and the power supply is not limited here. type of implementation.

[0023] Moreover, the power supply 1 at least includes a rectification and filtering unit connected to an external power supply, a power factor correction unit connected to the rectification and filtering unit, a transformer connected to the power factor correction unit, a switch assembly connected to the transformer and a connection The power modulation unit of the transformer. When the power supply 1 enters the operation power supply through the startup procedure, in addition to supplying a working power, it also generates a power good signal (Power_goo...

Abstract

The invention provides a method for avoiding the multiple re-starting of a power supply. During the implementation process, a power good signal generated during the normal operation of the power supply is received. After that, whether the power good signal is acquired or not is judged. If not, the power supply is required to be restarted. The restarting times of the power supply is recorded. After the power supply is restarted, whether the power good signal is acquired or not is judged again. If yes, the power supply is driven to work the same way and the restarting times of the power supply is returned to zero. If not, the power supply is required to be restarted again and the restarting times of the power supply is accumulated. The accumulated restarting times of the power supply is compared with a restarting limit number. If the restarting times of the power supply is larger than the restarting limit number, the power supply is forbidden to be restarted. Therefore, the problems that the abnormality cannot be eliminated by restarting the power supply and then information equipment is damaged in the prior art can be solved.

Description

technical field [0001] The invention relates to a control method of a power supply, in particular to a method for avoiding multiple restarts of the power supply. Background technique [0002] By the way, with the improvement of the computing power of information equipment, the requirements for the stability of information equipment are becoming more and more stringent. Therefore, some operators have proposed patents such as Taiwan Invention No. I271612 and I305303, hoping to solve the problem through the implementation methods disclosed in the above patents. An abnormality caused by the operation of the microprocessor. [0003] However, whether the information equipment works stably or not does not mean that the information equipment can work stably only by ensuring the normal operation of the microprocessor. The supply of power is also a part of the stable operation of information equipment, so some operators set it on the firmware interface (BIOS) of the information equip...
