Introduction: DIY Inverter 220V(250VA)

About: Myself Ramji Patel, I am an Electronic project Teacher, hobbyist and designer. In present I am pursuing my B-tech from Institute of Engineering and Rural Technology(I.E.R.T.), Prayagraj (Allahabad).

In this instructables I am going to make a mains voltage(220V/50Hz AC) inverter with maximum power of 200W(250V). I can use this inverter to light two 100W bulbs or 150W fan motor. I can use also use it to charge my laptop and smart phone. This inverter uses three main components i.e. A Inverter transformer(12-0-12), a 200W Inverter driver circuit and a 220V Lead acid battery. I have already prepared my inverter circuit and inverter transformer in my previous instructables. I have shared the links of those instructables if you want to make your own transformer and inverter circuit.
