Here is the simple tech. behind how to make home inverter. Inverter circuits are circuit used to convert DC to AC.
Components used for construction in how to make home inverter
- NE555 IC
- 12-0-12V/3AMPs /230V transformer
- 2N6292*2 Transistor
- 100k variable resistor
- BC547 transistor
- Battery 12V
- 01uf capacitor
- 22uf capacitor
- 15k*3 resistor
- 100k resistor.
Tools used for construction of home inverter
- Soldering iron
- Jumper wire
- Vero board
- Razor blade.
The work of some of the components in the circuit
NE555IC: it’s used in this circuit to generate 50HZ oscillator.
BC547TRANSISTOR: it’s used in this circuit as phase inverter.
2N6292 TRANSISTOR: it’s used in the circuit to control the output state which alternatively switch 850HZ frequency, when the output is apply to the 12-0-12 input of the transformer, the transformer will produce 230V AC as the output and it’s also produces a square wave 50HZ.
The circuit is using 12v battery but you can use any battery of your choice.
HOW TO CONNECT THE COMPONENTS
- Place your NE555IC on your Vero board.
- Connect pin 1 to the groin ground.
- Connect pin 2 and 6 together and connect one leg of 0.22uf and the other leg of the capacitor to the ground.
- Connect variable resistor to pin 2 and 6 and connect it to pin 7 and also connect 100k resistor to it and connect it to pin 4.
- Connect pin 4 and 8 together and connect it to the positive terminal port and also connect it to the center tap of the transformer.
- Connect pin 5 to one leg of 0.01uf and the other leg of the capacitor to the ground or negative port.
- Connect pin 3 to 15k resistors and connect it to the base terminal of the 2N6292 transistor and you then connect the emitter (E) terminal to the ground and the collector (C) terminal to the first terminal of the input of the transformer.
- Connect BC547 transistor to 15k resistor and then connect it to the pin 3 of the NE555IC, then connect the emitter (E) terminal to the ground and connect the collector (C) terminal to 15k resistor and connect it to the positive terminal.
- Connect the second 2N6292 transistor, by connecting the base terminal to the collector terminal of the BC547 transistor and the collector terminal to the last terminal input of the transformer and then connect the emitter (E) to the ground.
- Connect all the ground to the negative of the battery and all positive to the positive of the battery.
- Connect the output of the transformer to the equipment main to be used.
Note: in other to check if the frequency is up to 50HZ, you connect your oscilloscope probe to the circuit by connecting the black probe to the black terminal of the battery and the red probe to pin 3 (between Pin 3 and the leg of the 15k resistor) and if the frequency is not up to 50HZ, you then vary your resistor in other to complete or meet up to the standard of 50HZ required for the circuit to use, thereby generating a sound square wave at the output of the transformer.
To check the output of the transformer to know the exact range of the voltage, you use your Muiltmeter and set your node at 250ACV. And connect your probe to positive and negative terminals on the output of the transformer.
inverter is one of the circuit that uses NOT gate to work, thereby converting dc to ac, which can be used in solar and electric energy to supply light to our homes and offices.
