About: Share diy projects to those who have the same hobby with me

Hii friend,

Today I am going to make an Inverter circuit using 12V Relay.

let's get started,

Step 1: Take All Parts As Shown Below

Materials required -

(1.) LED Bulb - 220V x1

(2.) Input power supply -12V DC / (12V Battery)

(3.) Transformer - 12-0-12 x1

(4.) Relay - 12V

Step 2: Connect All Parts As Circuit Diagram

This is the circuit diagram of this inverter.Connect all components according to circuit diagram.

Step 3: Connect Normally Close (NC) Pin to Coil-1 Pin of the Relay

Firstly we have to short two pins of Relay.

Solder Normally close (NC) Pin to Coil-1 pin of the Relay as solder in the picture.

Step 4: Connect 0 Wire of the Transformer

Next solder 0 Wire of Transformer to coil-2 pin of the Relay as you can see in the picture.

Step 5: Connect 12 Wires of Transformer

Next solder one 12-wire of transformer to NO pin of the Relay

And solder another 12-pin of the transformer to NC/Coil-1 pin of the Relay as you can see in the picture.

Step 6: Connect LED Bulb to the Transformer

Next we have to solder LED Bulb to the output of the Transformer as shown in the picture.

Step 7: Now Give Power Supply

Now we have to give input power supply to the circuit.

Connect +ve input power supply wire to the common pin of Relay and

Solder -ve input power supply wire to the NO pin of the Relay as you can see in the picture.

Result - LED will start glowing.

Like this we can make 12V Relay to Inverter.

Thank you

    When I was a kid, my father had an antique Ford ignition coil that was used in early Ford cars, which used the exact same approach to convert battery voltage to the high voltage needed to fire the spark plugs. That unit had its relay built on top. Btw, this is very similar way that cars ignitions still work either via mechanical breaker point or via a solid state switch. Thanks for posting and bringing back some good memories.
