100W Power Inverter Circuit Diagram. You can use 12 V car battery as the 12V input power source. Adjust the potensiometer R1 to get the 50Hz output frequency. Use a 10 A fuse in series with the battery as shown in circuit.
Use step down transformer of 9-0-9 V , 10A. But the 9-0-9 V winding will be the primary and 220V winding will be the secondary (reverse).
