In this project we will convert the 4V to 220V AC by using transistor and transformer with some electronics equipment. In 4V to 220 V AC inverter circuit Dc current convert in to AC current. In this circuit we used scrape components to build the circuit and these components can taken from old mobile charger and CFL circuit.
1-Transistor 13005 or any NPN transistor
2-4.5 uF capacitor
3- 4 Volt Battery
4-Transformer from old mobile charger
6-10 to 110 ohms resistor
There are two type of inverter which is true /pre sine inverter and quasi or modified inverter. The pure sine inverter are more costly then the modified or quasi inverter .In modified or quasi inverter we used transistor and transformer to converter the DC current in to AC current.
During the section of transformer pin we used the point of transformer as a output where maximum resistance is available.
In the transformer if the 3 and 4 point have maximum resistance then we used these points for output. If 5 and 6 point have maximum resistance we used these point for output
Selection of Transistor
To make 4V to 220V AC Inverter project we can used any NPN transistor like D13003 or D13005 .The point of D13005 transistor are shown in the figure below.
The 4V to 220V AC Inverter circuit are shown below.
