How to Invert 12V to 220V

In my previous post, I share to you guys about the 12V to 220V inverter schematic. This time I would like to share again about inverter, but this time it’s how to make 12V to 220V inverter. The main component of this small voltage converter to transform 12VDC to 220VAC is the CMOS 4047. We will used this CMOS 4047 to stable the multi-vibrator, at pins 10 and 11 will have a symmetrical rectangular signal (square wave) which is amplified by 2 Darlington transistors and finally reach the secondary coil of mains transformer (2x10V/60W).

Below are the videos presentations of the comparison between without load and with load.

With the help of P1 the output frequency can be adjusted between 50Hz to 400Hz. Although this is not part of any professional dc ac converter it can be used quite effective on some home appliances. Be aware that the output signal is square and not sine wave. So you cannot use it for powering TV, Laptops, monitors. Use it only for lighting, power tools and other non-expensive equipment.

Below is the circuit schematic of the converter in 60 Watts  from DC to AC.

12v to 220v Inverter Schematic

I would like to learn on how to invert 12V DC to 220V AC for 100 watts that’s why I’m doing my research about this because I’m not an Electronic or even an Electrical Engineer.  So I need more info on how to do it right to avoid accident. By doing the research I found some techniques and tutorials on how to do it easy without deep understanding on it.

In this 12v inverter circuit diagram I used the IC 4047 – IRF540 instead of transistor 2N3055 because it is a good idea power output for 100W from the transformer 2-3A. For the information for those who did not know yet that AC can’t be stored for future use but DC can be stored for future use in a battery. The stored DC can be converted back to AC by using power inverters. Below is the schematic diagram of the inverter that I made.

I also created a circuit diagram inverting 12V DC to 220V AC for 500 Watts.
