Abstract

A method for using a DC battery to provide an AC voltage includes the following steps: providing a battery; providing two terminals for an output of an AC voltage power supply; providing two terminals for an output of a high-voltage DC power supply; connecting the two terminals of the AC output to the output of the high-voltage DC power supply respectively The two terminals of the battery; convert the low-voltage DC power supply of the battery into a high-voltage DC power supply; and exchange the two terminals of the AC output with a certain frequency to connect the two terminals of the high-voltage DC power supply output. In the present invention, the two terminals of the AC output are exchanged and connected with the two terminals of the high-voltage direct current power supply at a certain frequency to form an analog AC power, thereby realizing the use of the battery to provide the AC voltage.

Description

technical field [0001] The present invention relates to a method for providing AC voltage, and more particularly to a method for providing AC voltage using a DC battery. Background technique [0002] With the development of technology, various electronic devices or equipment are applied to people's daily life and work, respectively providing people with various conveniences and enjoyments. The normal operation of these electronic devices or equipment requires power supply, such as direct connection to the mains indoors (220V alternating current is used in mainland China). Sometimes users need to use electronic devices or equipment outdoors. At this time, for electronic devices or equipment that requires AC voltage, it is usually necessary to generate power outdoors, which is obviously very inconvenient. For electronic devices or equipment requiring DC voltage, batteries can be used for power supply, and currently, rechargeable batteries equipped with electronic devices or e...
