This is AC Inverter. Input 12VDC from car battery to output 220V AC 50Hz or 60Hz at Square wave signal. The main part is IC CD4047 and IC LM358 and Transistor 2SC1061 and 2N3055. The transformer is 12V-012V Primary : 220V Secondary. and current 3A up for power output than 100W. Note: C1 = 0.1uf [...]

This circuit power Inverter 100W, so input voltage 12V (battery 12V) to output volt 220V ac 50HZ, it is asy circuit because less component to use. It use IC CD4047 Squarewave Oscillator 50HZ and Power Transistor 2N3055 x 2 For driver transformer 220V ac to OUTPUT Power 100W min. Circuit Inverter 100W by IC 4047 [...]

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. How to calculate transformer rating The basic formula is P=VI and between input output [...]
