In this simple electronic project I have clearly shown how you can make 4v dc to 220v AC with a mobile charger transformer, we are going to construct a very simple low-power inverter. We have used some components/elements to make this electronic project. Even this electronic project/circuit can be made with scrap components available at your own home. An inverter circuit/project is used to convert the DC [ Direct current ] current to AC [ Alternative current ] current. You can make this project without any hesitation but it is an experiment circuit it can be used for commercial purposes.
There are two types of inverters:
- ✪ True/pure sine wave inverters.
- ✪ Quasi or modified inverters.
Pure sine wave inverters are costly & aren’t easily available while modified or quasi inverters are very easily available and cheap means less expensive.
Modified/quasi-inverters produce square waves and these are not used to power pure types of equipment. On the other hand, Modified square wave inverters use transistors and transformers to produce AC current from DC current.
In this electronic project/circuit, we have made a very simple inverter that can b used to glow the AC LEDs bulb of 1 watt however its power can be increased/maximized if you rewind the transformer yourself.
Components Required:
- ✪ Transformer: cellphone mobile charger [ 6 points ].
- ✪ Transistor: 13003 to 13005.
- ✪ Resistor: 10Ω to 30Ω [ Ω symbol of Ohm ].
- ✪ Capacitor: 400v 2.2uf or 4.7uf.
- ✪ Battery: 4volt.
- ✪ Led bulb: 220AC maximum 10w.
The points which have maximum resistance will take for output and other points can be used as input points according to the circuit diagram.
Transistor:
You can use any NPN transistor and we have used D13003 to 13005 NPN transistors in this electronic project circuit.
points of D13003 Transistor points are shown in the circuit diagram shown.
1.5v to 220v inverter:
The circuit diagram is presented there you can use it with a 1w led bulb only
