555 timer IC Inverter circuit schematic 12V to 220V

Posted on Feb 7, 2014

This article explains What is inverter And how can you construct your own simple low cost 12V to 220V inverter circuit. An inverter is nothing but a DC to AC converter. Inverters are very useful electronics products for compensating emergency power failure, as it performs DC to AC conversion. Here is the simple inverter circuit diagram using 555

timer IC. The astable multivibrator mode operation of 555 timer utilized here for AC oscillations and these oscillations are switched via transistor 2SC4029 to a transformer. The transformer step ups the voltage to 220V AC. Use a 12V battery and Battery charger circuit for this project. Design of inverter circuit is also given. The output pulse from the 555 astable multivibrator is fed to the base of power transistor 2N5192. The 2N5192 transistor works as a switch, so the 12V DC supply passed through the transformer at a rate of 50 times per second.
