Abstract

The present invention discloses a life-sustainable power supply system for a computer. The system comprises: a first rectifying circuit, wherein the first rectifying circuit is connected with an alternating current power source, and the output end of the first rectifying circuit is connected with a constant current stabilizing circuit; and a battery pack, wherein the contact end of the battery pack is connected with the output end of the first rectifying circuit. A positive electrode of each battery extends out of a first conductive slider; a negative electrode of each battery extends out of asecond conductive slider; each of the first conductive sliders is slidably provided with a first ring; each of the second conductive sliders is slidably provided with a second ring; the first ring and the second ring are concentrically arranged and synchronously rotated; the first ring is provided with a first plate, and the second ring is provided with a second plate; the first plate and the second plate are correspondingly spaced apart; the first conductive slider is in sliding conductive contact with the first plate; and the second conductive slider is in synchronous sliding conductive contact with the second plate. According to the technical scheme of the present invention, the technical problem that the computer with insufficient power supply is solved.

Description

technical field [0001] The invention relates to the technical field of power supply systems, in particular to a sustainable power supply system for computers. Background technique [0002] UPS is an uninterruptible power supply. It is a system device that connects the battery to the host, and converts DC power into commercial power through a module circuit such as the host inverter. It is mainly used to provide stable and uninterrupted power supply to a single computer, computer network system or other power electronic equipment such as solenoid valves and pressure transmitters. When the mains input is normal, the UPS will stabilize the mains and supply it to the load. At this time, the UPS is an AC voltage stabilizer, and it also charges the battery inside the machine; when the mains is interrupted, the UPS immediately The DC power of the battery is continuously supplied to the load with 220V AC power through the inverter switching method, so that the load can maintain nor...

Problems solved by technology

[0003] However, the existing UPS is connected to the computer power supply after rectification and inversion, instead of directly connecting the rectified DC power to the computer power supply. As a result, when the battery supplies power to the computer alone, it needs to go through inversion and rectification before it can be powered. Computer use, this method increases the energy consumption of the circuit and reduces the battery life

[0004] On the other hand, batteries are composed of several batteries. With the increase of use time, the terminal voltage of each battery will be different, which will lead to the premature end of battery discharge and affect the battery life.
