Electrical appliances in daily life use alternating current. Where power from the grid cannot be obtained, an inverter is needed to convert the direct current of the battery into alternating current. So how does the inverter complete this process.

How do 12 volt power inverters convert DC electricity to AC?

DC-AC inverters are widely used in homes and industrial environments, as the second backup power source when the utility grid is out of power. In the event of a grid failure or power outage, the inverter is very useful as an emergency backup power source. With the inverter power supply, you can still use household appliances, office appliances and industrial equipment normally.

Direct current (DC) is a current that flows continuously in one direction at a constant rate. For example, the electricity in a battery is direct current, which is usually used to power small electronic devices.

Alternating current (AC) is an electric current in which the direction of electron flow is switched back and forth at regular intervals or cycles. The current flowing in the power cord and the ordinary household electricity from the wall socket are alternating current.

How do 12 volt power inverters convert DC electricity to AC?

Direct current to alternating current is to change the original current of a certain magnitude and direction into a current that changes in magnitude and direction. Its working principle is to control the output of the oscillating signal through an oscillating chip, or a specific circuit, such as outputting a 50HZ signal, and then this signal is amplified to push the MOS tube, field effect tube or thyristor to continuously switch. After the switching action of this MOS tube, the direct current forms a certain AC characteristic. Then modify the circuit to get a sine wave AC similar to that on the power grid.

There are many technologies for DC to AC inverters. If you need them, please feel free to contact Xindun, we can provide you with products and services.
