Inverter Circuit Diagram
Information Posted in Energy
I remember when I build my first inverter, I was very happy and I invited a lot of friends to see my homemade inverter. At that time inverters were rarely available. I am sure you will feel the same if you successfully build this circuit. Before you start building this inverter circuit, I want to mention that this circuit involves 240V and 500W which can be fatal. You should take all security precautions before building this circuit. Preferably use electricity protective gloves and try not to play with the inverter circuit when it is operational. You will need little to medium knowledge of electronics in order to build this circuit. Alright, let us get to work. There are a lot of inverter circuit diagrams available online; some of them are complex and others are low performance. I have researched on a lot of them but in the end, I designed my own inverter circuit which is somewhat comparable to any professionally made inverter but still is simple enough for you to try.
Here is the inverter circuit diagram:
You will need the following parts.
- 2 Resisters 470 Ohm ¼ Watt
- 3 Resisters 22 Ohm 1 Watt
- 1 Variable resister 10K
- 1 Capacitor1uf
- 1 Capacitor 220uf
- 1 Zener diode 8.2V
- 1 IC CD4047
- 1 IC 7809
- 1 Transformer 12+12/240 (500W)
- 2 Transistors D313
- 12 Power Transistors TIP35C (make two pairs of 6 transistors each connected in parallel)
- 2 Heat sinks to fit power transistors
- Some wiring wire (for connections)
- A wiro-board (To build circuit on)
- A 12V battery of 12V power supply for testing purposes
I have used a two-stage regulated power supply to avoid frequency changes with the drop of battery voltage. First stage is 7809 which is a standalone voltage regulator. It converts 12V DC to 9V DC. Then we have used a 22 Ohm resistor and then a zener diode of 8.2V which forces voltage to stay at 8.2V. The 22 Ohm resistor is there just to aid zener diode by current limiting. The output frequency of this inverter circuit is square wave so it is not best to power up inductive loads so use it at your own risk. However, I do power up fans at home using this inverter and I never had any problems other than a little increase in fans noise. If you have any questions, please use the comment box bellow.
