Easy Homemade 50 watt Power Inverter
For making your own DIY 50 watt 12 V DC to 220 V AC Power Inverter UPS
Easy Homemade 50 watt 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 visit Make your own homemade (DIY) Electric Transformer)
- 22 gauge 2, meter 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
Method:
"Easy Homemade 50 watt Power Inverter" First of all you have to make some changes in transformer. If u are using 100 watt transformer then take 18 to 22 gauge copper wire and on the one side of transformer’s core make five turn and put a point on it, and turn this point, and again turn the wire five times on the same direction. In this way u get three terminals. If u r connect the transformer to 220 V power supply then it gives 1.5 V on both terminals. Now put transistor D1047 on the palm of your hand and turn it such a way that number appears your way. Now you will see three points. The point on your left side is known as (B) Base, middle one is E and the right one is collector(C). (These are the information only for D1047)
connect the E of both sides of transistors with the outer terminal of secondary coil, after that connect the both outer terminals of the third coil with the base of the both heat sinks of transistor. then connect the collectors of both side by wires n then connect the 500 ohm resistor on emitter and resistor on either side. Now connect the middle terminal of primary coil by one to two ft long wire and clip (crocodile) it and attach this terminal always by the positive terminal, and with the negative terminal of battery connect the both collectors of transistor.
After that the central point of the third coil and a wire attach it with emitter to connect using a heavy ampere switch between both terminals of the Inverter primary coil to apply a capacitor which will prevent the current from the sparking. inverter will switch on as soon as starting to work.
Working:
Easy Homemade 50 watt Power Inverter With both the terminals of battery connect the positive and negative wires to its terminals positive to positive and negative to negative and then open the switch, slightly vibration starts in the inverter as switch is open. Now you can run it into 1 to 500 watt load.

This inverter also can charge the batteries, you just need to( on and off) the switch.
Charging:
You will need to switch off for battery charging and connect the primary coil indirectly with 220 V of power supply, after that battery will start charging. To converts it into UPS you needs only one relay. These relays are AC 220 V and 4.4 terminals.

you should test with more than 12 volts it will work.the main problem is with transformers. in local (desi) transformer secondary coil cannot gives actual volt, its 13v to 15v. you should measure its voltage. or try to use 12+6 VDC battery. secondary coil output should be under 12 volts

when you will charge the battery you have to switch off between E and 3rd Coil connection.
make sure your transformer according to this project
you have to make only 5 turns around core what ever its volt is 0.7 or less that is not a problem .

@sami ullah
when you will charge the battery you have to switch off between E and 3rd Coil connection.
make sure your transformer according to this project
you have to make only 5 turns around core what ever its volt is 0.7 or less that is not a problem .

@sajjad ahmad the main function of transistors is to make pulse the the third coils terminals which are connected to transistor base give pulse to base and the transistors gives more power to transformer coils its frequency near about about 50 to 60 Hz.

2 D1047 is enough for 50 watt inverter. you should check the transformer secondary coil output voltage at 220 volt if it is more then 12 you need to increase battery voltage try 15 volts
