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

There four  CD4047 inverter circuits 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 build easily with PCB

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

100 watts Inverter using IC-4047, IRF540

This is the 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.

How to use CD4047 Monostable Astable Multivibrator IC

How it works

The 12V battery comes into the circuit. The IC1 will work as astable multivibrator circuit. Makes it products the square wave frequency, 50Hz out of both pin 10 and pin 11.

Then, the bias gate of both MOSFETs(IRF540) It works alternately the same style as this circuit.

Try 555 and MOSFET inverter circuit

We use CD4047 because the output is 50% duty cycle. It is better than 555 timer IC.

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.

Small AC inverter using CD4047

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 used in small size input 9 – 10 volts to 220 – 250 volts at a current of 1 Ampere.

LET’s build the DC to AC converter circuit.
12V DC to 220V AC 50HZ about 60 watts output.

    thanks alot admin… but plz my problem iz how to wind a transformer manually till it works just by instantly connecting it to 12dc supply. I’ve tried to wind it myself but its not producing a continuous ac power. am saying this coz there’s a man who have been building his and it works well even before connecting the transformer to the circuit!

    Have made many of these inverters for friends using bipolars or mos. For transformer, I used
    a high wattage 12 volts center tapped. This is readily available at electronic supply store.

  7. this 100watt inverter with mosfet is not working. mosfet give to me 2v which canot be step up????
    and at the gate of mosfet there are 12v volt then why mosfet not gave me 9v????
    plz answer me sir…………

    can we increase the output power by connecting mosfets in parallel ,do think it really works effectively,i mean does it increase the output power more than 100w

  13. Prasanjit Basak

    Please send me the working of this inverter..

  14. vishnu

    hi vasudev..,
    You can increase the output by connecting 4 mosfet s in paralal. You’ll get 250w-300w power. (Transformer must be rated to 5A)

    How come a 9-0-9 1.5A transformer serves 100Watt? Simple physics suggests its good enough for 14.5 watt max. Stop ruining the internet by publishing these shits all over the website. NONE of your circuits are based on facts, most of them are untested and not working. HATE HATE and HATE for you!

  25. i find that stuff interesting** ►► 2. 100W Square wave Inverter by CD4047, LM358 ◄◄
    → 4k7 resistors noise filter and smooth OpAmp inputs
    → low bandwith , low slew rate Op Amps !! quite likely !! provide non-overlapping drive for power switches
    → no unnecessary components — nice , simple , clear
    (although as the previous comment states – you need a good transformer and or cooling – to run it more than apx. 2 seconds on 100W output) + as i’m not too familiar with such designs — if we have a secondary open then the power likely regenerates proportionally at not active one at primary side . . . and might enter the Op Amp output + inverting input through NP collector-base junction of 2SC1061 . . .
    → . . . otherwise anything that’s already there** looks nice — i like that circuit (although i wouldn’t power it up like that)

    in what ic can use when it run the washing machine .

    • Hello, saif
      Thanks for your question.
      These circuits cannot power to the washing machine out of 300watts up.
      Because its the output is not more than 100watts.
