Method for providing ac voltage by DC battery

Abstract

The invention is a method of supplying AC voltage by DC battery, comprising the steps of: providing a battery; providing two output end points of an AC voltage supply; providing two output end points of a DC high voltage supply; connecting the four output end points, correspondingly; converting DC low voltage supply of a battery into DC high voltage supply; alternatively connecting two AC output end points to the two output end points of the DC high voltage supply at a certain frequency. Thus it forms analog AC so as to supply AC voltage by battery.

Description

technical field [0001] The present invention relates to a method for providing an AC voltage, in particular to a method for providing an AC voltage by 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 work of these electronic devices or equipment all needs power supply, such as direct connection to the mains in the room (mainland China adopts an alternating current with a voltage of 220V). Sometimes users need to use electronic devices or equipment outdoors. At this time, for electronic devices or equipment requiring AC voltage, outdoor power generation is usually required, which is obviously very inconvenient. For electronic devices or equipment that require DC voltage, batteries can be used for power supply. Currently, rechargeable batteries equipped with electronic devic...
