  2. what are transisters used between IC and MOSFETs. For lower wattage shall we use IRF44 like MOSFETs. and for 500W what is the Ampereage of the 12-0-12 transformer.

  3. hi, what value use the transformer 12-0-12 or 10-0-10 ?

  4. @ madurai chandru: the transistor use is irf3205, this simple circuit diagram can be use to power a small fridge and a TV set with some energy saving bulb, it is a simple inverter circuit for a beginner.

  5. @ constantinescu mihai: the inverter is a transformer base and not chopper or circuit base inverter and the transformer winding is a home made transformer winding formula which i have been using for any inverter winding, if i should start explainning how i wind the transformer it will take a longer time but if you have enough time to experiment this simple circuit diagram i will advice you to use a 12V UPS transformer of about 1KVA, am working on a video on how to wind a home made inverter transformer i will post it when am don with it, thanks

  6. modurai if you want to build a 500 watts inverter you can still use irf3205 but you can use total of four mosfet two on the right and two on the left side of the transformer, but if you want to use ifrz44 you can use a total of 6 irf mosfet transistor.

  8. please details of tranforrmer windins

    turns wire gauage

  9. ALSO NAME VALUE OF COMPONENTS USED

  10. the transformer winding formula that i use is totally deferent from the winding formula that is cormonly use but at the end same thin is been achieve, so if i start explaining how i wind the transformer number of turns u may not understand, but the gage that i use are gage 20 and gage 12

  11. the value of compunent are in the diagram, but the ic i use is cd4047

  12. Freeborn, the upper mosfet gates are connected to the positive line, are you sure it's correct??

    ReplyDelete
  13. swagatam thanks alot there is a mistake in the diagram, the upper gates is to be connected in-between the 1k resistor and the transistor the same way the lower gates is been connected, thanks for the observation. i will post a better diagram that will help beginners.

  14. Where is the diagram? i can't able to see anything...

    ReplyDelete
  15. Mr. FREEBORN, PLS EXPLAIN HOW YOU CONNECTED THE 470K VARIABLE RESISTOR, THE CENTER OR MIDDLE TERMINAL IN PERTICULA?

    ReplyDelete
  16. how to charge the battery is there any circuit for that?

    ReplyDelete
  17. Please can you point out the mistake on the diagram. Thanks

    ReplyDelete
  18. Please I want to see complete your diagram I am interesting because u not put the number of transistor and resistor please I want to know

    ReplyDelete
  19. Freeborn your blog is doing great nd you mastermind too, keep it up. I want to make my own 1000watts inverter but first i want to wind transformer myself with ur assistance i will do it. please i require the information from u on which u used. first; primary power, flux density(B)in tesla, current density in amps/mm^2 , Affective area of iron core, and efficiency please i'm waiting.

  20. which are those two resisters that connected to transistors? pls name the trasistor

    ReplyDelete
  21. Nice Post!! pretty informative..thanks for providing such a nice post.

  23. Mr M,,,,
    I"m not clear you diagram, can you post it again with correction and complete details .pls .

    dear freeborn emmanuel please mention two transistor name which is connected to pin no. 10 and pin no. 11 and its base resistance value please tell me fast thanks

    ReplyDelete
  25. you can use C945 and the upper MOSFET gates is to be connected to the collector of the C945 and not at the positive line please take note.

    ReplyDelete
  26. the resister value is 10k, nice China made inverter.

  29. Tell me please what number has resistances? two resistors are countless before transistor

    ReplyDelete
  30. thanks freeborn, i would have appreciated it much if u had included a page were you list the symbols and their meaning 4 easy understanding. all the same, thanks

    ReplyDelete
  31. hi , please sir can u flash me on this number (0265387227) so that i can call you.i am in Ghana. i don't succeed at any time i try building an inverter, please help me

    ReplyDelete
  32. please sir, kindly explain how to calculate power stage of an inverter, using mosfet transistor.

    ReplyDelete
  33. sir than you for the nice circuit i been searching for this type circuit and finally found but sir i have a question to ask be for i will stat build in the cd 4047 pin 4,5,6,where it should connected it connect with pin 14 or it unconnected thank you hope to hear from you

  34. Tell me please what number has resistances? two resistors are countless before transistors??

    ReplyDelete
  35. and what is the transistors after that two countless resistors?? is that TIP31??

    PLS REPLY.. TNX

  36. Hi freeborn, pls what's the difference between irf3205 and irf260,
    And also how many of it each will I use to build 1000w,
    Pls i need the real calculations of each of them. Thanks

    ReplyDelete
  37. hi freeborn, can you tell me the number of windings for primary and secondary windings since I want to rewind another transformer to serve that purpose.

  38. which type of transformer is that is it centre tapped

    ReplyDelete
  39. sir please tell me that how much amp transformer is used in this circuit
