Simple transistor inverter circuit diagram

In remote villages, there are often power outages, and some universities will automatically turn off the lights at a certain time, but that doesn't matter. With it, these can be solved.

This is a very easy-to-make inverter that can change the 12V power supply voltage into 220V mains power. The circuit is driven by a multivibrator composed of BG2 and BG3, and is driven by BG1 and BG2 to control the work of BG6 and BG7.

The oscillation circuit is powered by the regulated power supply of BG5 and DW groups, which can make the output frequency more stable.

During production, the transformer can be selected from the common mains transformer with dual 12V output. The capacity of the 12V battery can be selected as needed.
