Simple Inverter

Here’s a very simple circuit inverter that converts DC current into AC current, from 12V DC to 220V AC with output power of 5W max.

Simple Inverter circuit diagram

Inverter circuit is typically used for emergency lighting, since the power output is small, which is about 5W only. But you can use this inverter for other purposes that do not require large electric power such as mobile phone charger, small lamp/LED lamp, etc. Don’t use this circuit for electronic appliances which consume high power, of course it will not works. You may use 12V lead acid battery for this circuit.
