50 watt Power Inverters (12 VDC to 220 VAC) UPS
Make your own DIY 50 watt 12 VDC to 220 VAC Power Inverter UPS
Power inverter (UPS Uninterruptible power supply) is a very useful device which can convert Low voltage from a DC source to high voltage AC. The most common power inverter is 12V to 240V inverter. Perhaps that is because 12V batteries are common. This type of power inverter usually draws current from a DC battery. This battery should be able to provide a high flow of electric current. Normally lead acid batteries can server this purpose well. This current is then converted to 240V square wave alternative current so that we may empower those electric appliances which work on 240V instead of 12V. Inverter falls in the category of expensive devices so many people don’t buy them even they need them. What if I tell you how to build an inverter (UPS Uninterruptible power supply) yourself?
There are a lot of inverter circuit diagrams available online; some of them are complex and others are low performance. I designed my own inverter circuit which is comparable to any professionally made inverter but still is simple enough for you to try.
You will need the following parts.
- Transformer 12+12/220 (50W) ( you can make your own inverter transformer
- 2, metter copper wire (for winding)
- 2 Transistors 1047
- 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
- 1 Resisters 1 k
Here is the inverter circuit diagram:
