Introduction
If you’re planning to go on a road trip or camping adventure, having an inverter that can convert 12 volts DC to 220 volts AC is highly advantageous. It allows you to plug in and power up your electronic devices, such as laptops, cameras, and smartphones, just like you would at home. Inverters come in different sizes and wattage capabilities, so it’s essential to choose one that suits your needs. The most common types are modified sine wave and pure sine wave inverters. Modified sine wave inverters are more affordable but produce a less clean waveform than pure sine wave inverters which can affect the performance of certain sensitive electronics. A 12v to 220v inverter is an excellent addition to any adventurer who wants access to the comforts of home while on the road.
In this video I have made a 100w inverter without using any ic it is very easy to build at home hope this will help you.

Working Explanation
Making a simple 100 watt inverter to convert 12v to 220v is not as difficult as it may sound. First, gather all the necessary components, which include a 12V battery, a transformer, two mosfets, two NPN transistors, two diodes and three capacitors etc., as per list of components provided below. Connect the mosfets and transistors according to the below circuits using a breadboard or pcb and connect them to the transformer’s primary winding. The secondary winding of the transformer should then be connected to the AC load.
Finally, connect the diodes on either side of your circuit to prevent any reverse current from flowing back into your inverter when you turn it off. Test out your circuit and make sure that it is working correctly before putting a load on it. Remember to take safety precautions such as wearing rubber gloves while handling components or conducting tests with voltage meters. With these few steps, you’re now able to create your very own simple inverter at home!
