100VA to 220VA MOSFET based Inverter kit circuit

100VA to 220VA MOSFET based Inverter kit circuit

This is a basic square-wave oscillator based inverter kit. Based on the 4047 I.C oscillator, we discussed here, it is a finalized PCB version of that inverter with MOSFETs.

Here are two MOSFETs, one for each channel and this board consists of reverse diodes in MOSFET section for battery charging support.  With FB4710 or P55NF06 or IRFZ44 or IRF540 MOSFET, we can get output power of 150VA, 180VA, 220VA, and 100VA.

The setup is simple, just download the 300dpi non-reflected PCB layout from below, and place components as you see in the above images.

I’m not going to give you headache of complex circuit now, just follow what you see in images, and if you have comments/questions, ask them below in comments section.

    sir,i am doing project on ” Diabetic Neuropathy”…i need a Retriggering circuit for IC HCF4047BE …Can You please help me…….

  2. microman

    can i use this transformer for this circuit?????? 12-0-12 1.5amp

  3. Venkatesh

    Dear Sir,

    I am design inverter circuit using 4047 ic and the output came 250V 50Hz, i i connect 20W lamp the AC output decrease to 170V what will do to maintain the outut voltage.
    please send the details

      You can use 9-0-9V 10Amp transformar. Then when you connect a more than 25 watt LED your transformar nicely output 220 to 240 AC voltage. But when you connect 12-0-12 V 10Amp transformar, your transformar only handel to supply 220V A.C. for a one LED. But if hot reduice your transformar 10Amp to 5Amp your your output watt reduice 100watt to 60watt. And now if you faced any problems then you connect my. My no 9859659965

        Sir
        I HV used irfz44
        And 12-0-12 ,10a transformer
        And 35ah 12 v battery
        When I connect load MOSFET burning after some times

        • Eswar N

          IRFz44 MOSFET has low capabilities.so use the p55nf06 MOSFET.it will hold some time and gives some better result.

  4. sumit

    sir,plz kya is circut ko 500waat ka bnana ho to kya krna pdega mere pas 12-0-12 .10amp ka transformer hai par us se bhi iski power 100wat hi rehti ha mai is inverter se ghar ka pnkha chalana chahta hu.

  5. tabesh

    can I make 2 kw inverter by this diagram?

  6. James Smith

    Hi Arup,
    I am searching for data sheet of T8C8F transistor or equivalent. Can you help me get an equivalent of any alternative for the transistor.

  7. salem

    what is name of program to show you that 50hz and that wave ?

  8. marino

    Thank Soo much big brother…becuase of your circuit i learn a lot…bless you always with good health….

    • Arnab

      Yes, as they are powered by the SMPS built inside the charger/power supply unit.

      • Roz

        Is the cd4047 model different from the hcf4047 model ???

  9. ELEC

    How much should a potentiometer be?

      • ELEC

        I mean the potentiometer, which should be on a few!

  10. vhafuwi

    What do ineed to make it 500 watt , how many pairs of mosfett , I have 600 watt 12-012 trafo

  11. Mairiga Emmanuel

    hi,, I just need the circuit diagram for the circuit. cause I don’t to those things for the pcb

  12. KANHU

    best mosfet for 10 A transformer is IRF3205 .
