Introduction to INVERTER:

An inverter is an electric apparatus that changes direct current (DC) to alternating current (AC). It is not the same thing as an alternator, which converts mechanical energy (e.g. movement) into alternating current.

Direct current is created by devices such as batteries and other sources. When connected, an inverter allows these devices to provide electric power for small household devices. The inverter does this through a complex process of electrical adjustment. From this process, AC electric power is produced. This form of electricity can be used to power an electric light, a microwave oven, or some other electric machine.


In this project we come across with high voltages (220AC) please do not touch any input,output and circuit handle with care.


This inverter can be used only for a bulb, please do not use any mobile chargers.


  • Bulb and lamp holder
  • Electrical Switch

  • Transformer 12-0-12/1ampere


  • DPDT relay 12v

  • 1 micro farad capacitor of 50v


  • Soldering gun


  • Connecting wires



Take the transfomer and connect the input source at the primary end.


Take the DPDT Relay 12v ic and connect the capacitor to it using soldering gun


Connect the wires to the secondary end of the transformer to take the output

and connect those wires to DPDT relay.


Now connect two wires to DPDT relay to take the output.


Connect these wires from DPDT to bulb holder.


Make connections properly using soldering gun and add a switch to circuit.


Now connect the UPS /power supply to transformer (at the primary end)

and on the power supply.


Fix the bulb to holder.


              Make sure that the circuit is closed and be care full while handling with power.
