Four CD4047 Inverter circuits 60W-100W 12VDC to 220VAC

This is three CD4047 inverter circuit can convert 12VDC to 220VAC 50HZ we use IC-4047 for oscillator and transistors driver the transformers to output. we have 3 circuits you can builds easy with PCB


1. 100 watts Inverter using IC-4047,IRF540

This is inverter 100W circuit, use IC 4047 alike inverter 100W transistor I use Mosfet IRF540 instead Transistor 2N3055.

It good Idae, power output 100W from transformer 2-3A.

2.Square wave Inverter using CD4047,LM358,2SC1061,2N3055

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 (or IC 4047 Series) 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.
C1 = 0.1uf metalized-film capacitor, 5% tolerance.
R1 = 47K for 50Hz output, 39K for 60Hz output.

3.100W Inverter by IC-4047,2N3055

This is 100W Power Inverter that input voltage is 12V (CAR battery)
to output volt 220V AC 50HZ. It is easy circuit because less component to use.
It is used IC CD4047 Square wave Oscillator 50HZ and
Power Transistor 2N3055 x 2 For driver a transformer 220V AC to OUTPUT Power 100W min.

60 watts DC to AC converters circuit using IC-4047

This is a small AC inverter. There are very small amounts. For the experimental study. Because low power of around less than a 60 watt only. However, you still can get a good basic circuit course.

This circuit we use an IC-4047 as astable/monostable multivibrator that low power is main of circuit


In the operation of circuit. To change the 12 volts direct current into AC electricity of 245 volts. Based on circuit in Figure 1 this. IC1 is connected to the astable multivibrator. There is a Square wave signal appear at output pin + Q and-Q on Symmetric form. Then is amplified by dual Darlington transistors T1(BD699) and T2(BD699) , and after then is send to Primary winding of the transformer low voltage (2x10v 60 VA)

The output of 245 volts at the secondary winding of the transformer with a frequency between 50 – 400 Hz, depending on the P1.
The transformer is use in small size input 9 – 10 volts to 220 – 250 volts at a current of 1 Ampere.
