Two IC Used in this circuit. Multivibrator CD4047 And Opamp Comparator LM324 . 6 Power Transistors are Used to make High Load Capacity Inverter. Connection Of Transformer Must be Reversed. Reversed means The Primary Terminal Is connected with Output And Secondary Terminal Of Transformer Is connected With Input In The Circuit As shown in the diagram.Use Proper Heatsink With Transistors. Using this circuit you can convert the 12V dc in to the 220V Ac. In this circuit 4047 is use to generate the square wave of 50hz and amplify the current and then amplify the voltage by using the step transformer.
Careful With high AC Voltage.
