The inverter is an electrical converter that converts DC to AC. This is a very simplified schematic diagram of a 12v 220v pure sine wave power inverter, which is used to convert energy from solar PV panels to alternating current.

The inverter can be controlled in many ways. Pulse width modulation is a very common method. For the inverter schematic shown above, four power switches are used. These switches are usually implemented using a combination of power transistors and diodes. By operating the switch, it produces an AC output voltage similar to a pure sine waveform at the grid frequency. This is a basic simplified description of the working principle of the inverter.

The pure sine wave inverter produces the same alternating current as the grid, which can load all electrical appliances that the grid can load. Xindun focuses on the research and production of pure sine wave power inverters, voltage 12v/24v/48v to 110/220v/230v/240v. If you have any questions, please contact us.
