Intelligent power supplier

Abstract

The invention relates to an intelligent power supplier, which is connected with a phase line and a zero line of an alternating-current mains supply. A master switch and two parallel switches arranged on the rear of the master switch are arranged on an alternating current supply line; one of the two parallel switches controls a primary device, and the other switch controls the power supply of a secondary device; and an intelligent control circuit is respectively utilized to control the on-off of the three switches. The intelligent power supplier can capture the startup and shutdown actions of the primary device to automatically and orderly start up or shut down the primary device and the secondary device; moreover, the intelligent power supplier has the functions of automatic shutdown, time shutdown, false startup prevention, false shutdown prevention and frequent startup and shutdown prevention, and can prevent blind shutdown caused by the overvoltage and under-voltage of the power supply; and after shutdown, not only the power input ends of the primary device and the secondary device connected with the intelligent power supplier are thoroughly disconnected from a power network inorder to prevent potential safety hazards, but also the standby electricity consumption of the primary device and the secondary device connected with the intelligent power supplier is zero, thereby achieving the effects of reducing electricity consumption, ensuring use safety and enhancing and prolonging service life.

Description

technical field [0001] The invention relates to a power supply device, in particular to a power supply device for electric appliances. Background technique [0002] Today, with the development of technology, the varieties of electrical appliances are changing with each passing day. Among them, quite a large class of electrical appliances belongs to the system or combined products with master equipment and slave equipment, such as: computers, in addition to the host computer, also have peripherals such as monitors, printers, and scanners that are connected to the host computer and work together. For example: home audio and theater systems, in addition to sound and light terminal equipment such as speakers and / or display screens, there are also many equipment such as players, DVD players, power amplifiers, and equalizers. Most of the power supply devices of these electrical appliances are just a simple multi-position socket, which does not directly meet the actual power suppl...

AI Technical Summary

Problems solved by technology

The technology is simple and the function is single, which is far from meeting the actual needs. Although it can realize automatic shutdown and standby energy saving functions, because it uses a relay to uniformly control the power supply of the computer host and peripherals, it not only violates the computer and its peripherals. The basic requirements of sequential startup and shutdown in the application will also generate a surge impact up to 7-10 times the rated current during startup and shutdown, causing great damage to the computer host and peripherals
