Abstract

The invention relates to a power supply device. the power supply device comprises a switch circuit, an output circuit, a standby circuit, a discharging circuit and a control circuit, wherein the output circuit is connected with an external power source through the switch circuit to output a main power supply; the standby circuit is connected with the external power source to output a standby power supply; the discharging circuit is connected between the output circuit and the external power source to generate a discharging path; the control circuit is connected with the external power source, connects the switch circuit according to a normal operation node so that the power supply signal of the external power source can be transmitted to the output circuit, disconnects the switch circuit according to a standby operation node so that the first period or second period of the power supply signal can be transmitted to the standby circuit and connects the discharging circuit when the external power source is removed so that the power supply device can discharge by the discharging circuit.

Description

technical field [0001] The invention relates to a power supply device, especially a control method and a discharge method of the power supply in a standby operation state. Background technique [0002] The advancement of science and technology has provided many electronic devices with different functions in the life of modern people, which is convenient for people to enjoy and also accelerates the dissemination of people's various information, such as: TV, computer, workstation, network domain, etc., relatively also need Provide larger and more stable power support. Used for work, games, communication or information processing, etc., almost completely rely on computer equipment for processing. Therefore, computer equipment must be able to provide stable operation to facilitate people's use. At present, general computer equipment generally includes a central processing unit (Central Processing Unit, CPU), a chipset, a memory, a storage device, an interface connection device...
