  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 ?

    ReplyDelete
  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.

    1. pls sir what were those component connected to before connected to the negative expectially pin 7

  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

    1. sir can i use a simple 220V to 9V stepdown Transformer?

  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.

  9. ALSO NAME VALUE OF COMPONENTS USED

    ReplyDelete
  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

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

    ReplyDelete
  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.

    ReplyDelete
  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.

    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.

  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.

  45. This is great work.... keep it up.
    and I will soon build this one.
    but, I have question on use placement of 470 pot. It has 3 pin, 1 at back and other 1 at front. which of them goes to PIN 1, 2 and 3 of the IC4047.
    Thanks once again, My God help.

  51. dear brothers
    I want to make a 800-1000w transformer for ips. I have bought all component to make it. here is the list.
    CABLE:-
    AWS 21 for primary winding,
    AWS 12 for secondary winding,
    CORE:-
    4.5 inch
    FORMER:-
    3.05"/7.747c.m.
    1.6"/4.064c.m.
    The transformer is make by 12-0-12V secondry and 0/N-140-220-260V
    Plz help me to find out how many turn will be in primary winding and secondary winding

  63. I think the connection diagram of cd 4047 10 and 11 to transistors are tip31 type transistor used. and the equivalent transformer voltage should not 12 it should be rather 24 volt to in order to prevent the ir3205 burning
