12v DC to 240v AC Voltage Inverter

This is a very basic and simple circuit which will generate 240v of AC o/p at a frequency of 50Hz given the input is around 10v to 16v.















Components needed:
You can easily figure out what components are needed for the circuit.

Working:
The circuit contains an astable multivibrator using 555. For low voltage o/p of multivibrator, Q1 will be OFF and Q2 will be ON, and for high voltage o/p of multivibrator, Q1 will be ON and Q2 will be OFF.
This ensures regular input to Transformer.
Rest of the process is up to Transformer. A transformer of specific ratio will give the needed o/p of nearly 240v.

Notes:
The capacitors used in the should be Tantalum capacitors because Ceramic or Electrolyte will tend to blast at these type of power operations.

Hope you will find it interesting and helping....

  1. I used 555 as an oscillator to drive four mosfets for my inverter, and the AC voltage keeps dropping on load increase. What could have caused it? Any solution to it?
