Simple inverter 3.7V to 220V
Hi friends, in this video I will make a simple inverter using 5 volt charger. I'm using the transformer from the broken charger. to increase the voltage from 3.7 volt to 220 volt. This is a simple self oscillating inverter its very simple you just need only 3 components transformer, 470 ohm resistor, and transistor. I'm using npn transistor TIP41 other transistor will work like 13003 or 13005 but hey will give half of the power. This circuit doesn't have any output regulations so the output voltage depends on the output load. you can glow 3W to 20W LED light bulbs. but the out put frequency is very high so. some light may not work
Hello guys, In this Instructable I will instruct you to make your own 1.5v DC to 220v AC inverter with less number of components.

Inverters are often needed in places where it is not possible to get AC supply from the Mains. An inverter circuit is used to convert the DC power to AC power. Inverters can be of two types True/pure sine wave inverters and quasi or modified inverters. These true /pure sine wave inverters are costly, while modified or quasi inverters are inexpensive.
These modified inverters produce a square wave and these are not used to power delicate electronic equipments. Here, a simple voltage driven inverter circuit using transistors as switching devices.
This video gives you all the information you need to build your own 1.5v DC to 220v AC inverter. During the next steps however I will present you some additional information to make the project even simpler.
Here you can find the circuit.
You can see my PCB traces and it is easy to understand while making.
Place all the components on the PCB according to schematic.
Solder all the components carefully.
After circuiting now the time to test with a 220v bulb.
