Power Inverter 100W, 12V DC to 220V AC

Here is 100 Watt Inverter 12V DC to 220V AC schematic diagram. This circuit designed using the combination of main components IC CD4047, Transistor TIP122 and 2N3055.

Circuit Notes:

  • A 12 V car battery can be used as the 12V source.
  • Use the POT R1 to set the output frequency to 50Hz.
  • For the transformer get a 12-0-12 V, 10A step down transformer. But here the 12-0-12 V winding will be the primary and 220V winding will be the secondary.
  • If you could not get a 10A rated transformer , don”t worry a 5A one will be just enough. But the allowed out put power will be reduced to 60W.
  • Use a 10 A fuse in series with the battery as shown in circuit.
  • Mount the IC on a IC holder.
  • Remember, this circuit is nothing when compared to advanced PWM inverters.This is a low cost circuit meant for low scale applications.
