4 volts simple inverter: In mini electronic projects, conversion of DC voltage to AC voltage is a very interesting and common problem. In most circuits, we observe that almost all design of circuit takes the AC input and gives DC output. But, as we want to change the circuit from DC to AC then a DC to AC converter circuit is used. The converter/inverter is required for this purpose. So, to convert the DC to AC converter circuit is used.
In this mini electronics project, I am going to make a very simple but very very interesting circuit. This circuit is 4 volts DC to 220 volts AC. I have used very simply and scraped components to build this circuit. These components are founds in mobile chargers and also in the CFL circuits.
4 volts simple inverter circuit diagram
Components Required 4 volts simple inverter
- Transformer from old mobile charger circuit
- 10 to 110-ohm resistor
- 13005 or equivalent Transistor
- 4.5uf capacitor from old CFL circuit
- 4 volts batteries
- some Piece of Wires
Transformer ( From mobile phone charger or equivalent)
In this circuit, we can use a mobile phone charger transformer. Keep in mind all mobile phone charger circuit has a different structure of the transformer. So you must check the transformer structure before using it in this mini 4 to 220v inverter.
Measurement of This type of transformer
you can measure this transformer by using a multimeter. We must have to use the maximum ohm coil of the transformer for output.
If Does not Work through this connection then just make a little change. Resistor connection replaces with point no 6 to point no 5. The jumper of + changes from point no 5 to 6. The circuit diagram is given below.
Alternate Circuit Diagram for 4v inverter
If the above circuit does not work then change the connections like the given below circuit diagram it will work 100 percent. It is a very simple 4 volts simple inverter that is why it’s power is very low so uses minimum watts as output to get the result.
Note: Because it is a developed transformer for the mobile charger so it is a very low power transformer. You can make your own transformer for better results of this inverter. because it’s very short with few components power inverter that is transistor may heat. So use a heat sink with a transistor.
