Easy Homemade 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.

  • 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

Method:

First of all you have to make some changes in transformer. If u are using 500 V 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 transformer 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:

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.

    Assalam Alekum sir i am glad to say that this project is awesome ,,, but i am facing some difficulties related to this project ...,
    <>
    1. The transformer i have purchased is not open , mean its windings are not seeable so what i do.
    2. Can i use more then two transistor with type of transformer to run high voltage appliances.

    Sir please answer , on current page or mail me , will be very thankful to you....
