Abstract

The invention provides a power supply. The power supply comprises a power supply module and a main power supply control module electrically connected to the power supply module; the main power supplycontrol module comprises an N type MOS transistor and a signal processing module, the drain electrode of the N type MOS transistor is electrically connected to the power supply module, the source electrode of the N type MOS transistor is electrically connected to the output end of a main power supply, and the grid electrode of the N type MOS transistor is electrically connected to the signal processing module; when a main power supply on signal is received, the signal processing module starts to and continues to apply voltage with a voltage value larger than a first voltage value on the grid electrode, and the first voltage value can make voltage between the source electrode and the drain electrode breakover; when a main power supply off signal is received, the signal processing module starts to and continues to apply voltage with a voltage value smaller than a second voltage value on the grid electrode, and the second voltage value can make voltage between the source electrode and thedrain electrode off. The N type MOS transistor is additionally arranged on the basis of an ordinary power supply, and the functions of the main power supply and a stand-by power supply are achieved.

Description

technical field

[0001] The present invention relates to the technical field of communication equipment, in particular to a power supply for communication equipment. Background technique

[0002] At present, the power supply of a computer usually includes a main power supply for maintaining the normal operation of the computer system, and a standby power supply (that is, a standby power supply) that can provide a weaker current when the computer system is turned off; when the computer system is turned off, the main power supply will stop supplying power , but the standby power supply will continue to supply power, so that the computer can be connected to the network, and the administrator can remotely control the computer and turn on the main power supply remotely, thereby realizing remote booting; and before the main power supply is turned on, relying on the standby power supply, the computer can Relevant components are tested, and after passing the test, the main power is t...
