Abstract

The present invention discloses an AC and DC emergency power supply which comprises a removably fixed upper shell, a bottom shell, and front and back panels which are arranged at the opposite side faces of the upper shell and the bottom shell. A charging and discharging circuit board and a polymer lithium battery group which is electrically connected to the charging and discharging circuit board are arranged between the upper shell and the bottom shell. The charging and discharging circuit board is provided with a MCU control chip and an alternating current generator which is electrically connected to the MCU control chip. The front panel is provided with a power supply switch, a direct current output control switch, an alternating current output control switch and a direct current charging port. One side of the direct current charging port is provided with an LED lighting lamp and an LCD display screen. According to the AC and DC emergency power supply, the two modes of AC pure sine wave and DC output different voltage is realized, through AC safe output control mode safe power supply, the power supply needs of different electrical equipment are satisfied, the use of all digital products and home low-voltage electrical appliances are satisfied, and the AC and DC emergency power supply has a simple structure and is convenient to carry.

Description

technical field [0001] The invention relates to the technical field of mobile power supplies, in particular to an AC / DC emergency power supply. Background technique [0002] The existing mobile power supply can only output a single AC or DC in function, and the output AC is mostly a square wave or a modified sine wave, which cannot satisfy all household or medical electronic products. In terms of the use of low-voltage DC, the output rated There are few voltage sections, which cannot meet the needs of all digital products and household low-voltage small electrical appliances. Contents of the invention [0003] The purpose of the present invention is to provide an AC-DC emergency power supply, which can realize two modes of AC pure sine wave and DC different voltage output modes, realize AC safe power supply, and has a simple structure and is easy to carry. [0004] In order to realize the above-mentioned purpose of the invention, the present invention adopts following tec...
