This is a basic and very simple low power inverter to convert 12V DC to 120V AC. How much power this simple inverter can handle the load depends the transformer current value and transistors you use for Q1 and Q2.

Inverter 12V DC to 120V AC Component List:
C1, C2 : 68 uf, 25 V Tantalum Capacitor
R1, R2 : 10 Ohm, 5 Watt Resistor
R3, R4 : 180 Ohm, 1 Watt Resistor
D1, D2 : HEP 154 Silicon Diode
Q1, Q2 : 2N3055 NPN Transistor (see “Notes”)
T1 : 24V, Center Tapped Transformer
Misc:
Wire, Case, Receptacle (for output)
Fuses, Heatsinks, etc.

Note: Don’t try to run inductive loads (motors) using this inverter.

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.
