12 Volt to 220 Volt Inverter 500W

This is circuit Inverter 12VDC to 220V 50Hz 500W.
It easy to make and Low cost.

Friends favorite circuit about the the inverter, because like working outdoors, or to backup storage to use when necessary.
Most of this is circuit low power, which is not suitable for practical applications. My friends said that he would be about 500 Watt.

It is a good size. Use with television receivers and light bulbs as well.

When looking for circuit. I get headaches. If you are a beginner or I can not buy expensive good quality circuits. Requires only one transistor. Or if you have free time. I want to build old circuit is alive again. This circuit will accommodate all your needs. It is a simple circuit. The same principle, I take battery voltage 12V to produce a oscillator about 100 Hz and pass to a two frequency divider circuit is only 50HZ. And drive a 10 ampere transformer with 10 x 2N3055 transistor in parallel. By a single transistor has 2A, when I use 10 transistors or 5 pairs of drive high current output. The complexity of circuit, but the principle is not it, and it is the number of transistors on a basic, easy to buy. You may be modified 100 watt power inverter To the size of transistors and transformers as well.

Note:
1. Battery for this projects.
If you need 500watt output inverter your battery must be 45Ah. (500w/12V = 41A).
Maximum current for 1 hour.

2.The solar battery charger( 18 volts solar voltage)
Full sunrise power on day about 5 hour.
So you need current from the solar is (45A/5hour = 9A)
or 9A x 18V = 160 watts.

    This project is simply great. If this could be upgraded to 1.5kva pls tell me how to go about it.

  • Michael John

    Hi guys please could you send me a clearer and enlarged circiut and if the circuit can be uprated to 1.5kw please advise. Thank you

  • rex

    hey guyz.. what is DX and RX in schematic ??

    can i use only 4 2n3055 transistor??

  • seen

    when i do simulation on proteus.. i did not get the output 220

  • admin

    Hi, Michael John
    I suggest not should build your own. Because it has low performance. And more expensive.

    You can buy 1500 watt shop or http://www.amazon.com/gp/product/B00126IDDC/ref=as_li_ss_tl?ie=UTF8&tag=all_electronic_components-20&linkCode=as2&camp=1789&creative=390957&creativeASIN=B00126IDDC

  • admin

    Hi, @seen
    You can use 4x2n3055 but lower watt than this circuit about 100-200 watts.

    and
    The transformer not need layout on PCB because it big size.

  • Junrev

    Hm..i already made this circuit inverter and i read some questions that need help. The resistor w/out wattage is all 1/4 watt cfr,and the 1N414B you may use 1N4148 for fast switching,and also the DIODE DX2A it means its a diode,you may use 1N5402,and to be able to have an output fix to 500 watt the transistor should be 14 pc’s and it means 7 channel bec.the 1st stage of 2n3055 is just to switch on or power the other channel..RX Is also mean it is a resistor 10watts 0.01ohms wire wound and also remember the 22ohms 10 watt is also a wire wound and should be in heatsink or blower coz it will be over heated in hour of used just in case..thanks for this circuit i never worry in black out here in our area philippines..thanks autor and admin..

  • Junrev

    My mistake the RX should be 10 watt 0.1ohms i just corrected it..peace

  • seen

    admin,
    thanks 😀

  • admin

    @seen You welcome I am not good electronics.
    I like collect electronic circuits only.

  • try and failed

    can you give a lil explaination of 100ohm 1/4watt? can i use 100ohw 5watt instead?

  • lah

    Junrev, have u finished with your simulation? is the output produces 220VAC?

  • Junrev

    @lah yes i already finished it and it works great,yes the output is 220V 50hz but if the battery is fully charge it will be about 225V believe me the circuit works great but you should put a heatsink or blower in resistor 10watt 22ohms to prevent over heating and use 14 pieces 2N3055 instead of 10, the costlier one is the best,for ex. The toshiba 2n3055 is the best i can suggest..and also be carefull when building it,.c0z it will harm you,make sure the connection of the transistor is correct coz once you have an error specially in 2n3055 transistor all of them will be leak or shorted so do it with care..sorry for my bad english im not really good on it..peace

  • Junrev

    @try and field the 100ohm 1/4 watt in the 1st channel between DX2A is ok but if you like to make it 5 watt sure why not?.much better but never change the value of the 100 ohm..

  • seen

    @junrev you using transformer cnter tap 500VA??

  • seen

    @junrev do you have a simulation or picture for that inverter..
    I have made that inverter for my final project using circuit above…but it not working..
    hmmm. :(
    can you give me something for me to troubleshoot..

  • Junrev

    @seen yes i used 500VA center tapped transformer tamagawa brand.maybe you have an error…sorry i dont have a picture of it..do you really know how to read schematic diagram?. If you have a mistake the circuit wont work specially transistor..know how to read the base,collector and emitter..i suggest to check the all transistor coz maybe you already damage it..try to check the connection or wirings..and check also the diode polarity..thats all i can help…if you really dont know how to read schematic i suggest you to practice it by the help of professional technician..im a technician but still im moderate in electronics..peace…

    Provide me inverter circuit

  • i m John i want to make an inverter plz provide me the circuit.

    How can i made 1000wats inverter?

  • bayani rabago

    I think,if anybody want a higher wattage of the inverter,then u hav to alter the wattage of small value resistor like the .1ohm to higher wattage,and add another stages of the power transistor(e.I)3055 and replace the transformer volt amp rating with a higher vamp rating.u can also utilize your inverter into making it a charger so u won’t need another gadget to recharge your battery.,just by adding a couple of heatsinked diode or rectifier,a capacitor and a dpdt switch ..to those who want to make the 50hz frequency to become 60 it is not impossible but a very complex ckt you will have,a costly one.anyway u still get a square wave on the scope which is not suitable for some device or appliances.

  • jeffrey

    what kind of this transformer? is this available or common in the market? how much the amper of this transformer? reply pls

  • jeffrey

    what kind of transformer

  • jeffrey

    it is the transformer that has primary winding of 220V ac and the secondary have center tap output of 12v? how much the amper? reply pls. because I choose this for my thesis… in this month

  • jeffrey

    i mean the output secondary of the transformer have 12v 0 12v?

  • JOHNPINE

    hello fellas i correctly followed the schematic diagram then finished it, and the inverter produces output of 220vAC and worked for just only 20 seconds with a Load (bulb) ( the 22ohm 10watt seems hot ). after that 20 secs, the output voltage decreases slowly to 190, 180, then jump to 54vAC. so bad not reading this posts

    so i’m gonna follow what @junrev recommend.
    i’ll post again..

    Pls sir, can i use 60watt with 18volt solar panel to power this 500watt inverter with battery backup?

  • momename

    Hi General Omosco.
    Thanks for you feedback.
    I think it cannot use because lower solar watts. Full power on day about 5 hour.
    If you need 500watt output inverter your battery must be 45Ah. (500w/12V = 41A).

    So you need current from the solar is (45A/5hour = 9A)
    or 9A x 18V = 160 watts.

  • General Omosco

    Please any body with 400watt or 300watt inverter circuit should please send me the link or send the diagram through this email guruzhostz@gmail.com

    Hello Sir, I have tried the circuit but having some issues. The 0.1/10watts drop i could not get from electronic shop so i used 0.047/10watts and its getting very very hot when i connect my 12v batt. and also there is no 220v coming out of the transformer. Can u pls advice on what to do?????

  • Tee

    Also forgot to tell u i used just 4 of the 2N3055 not all the 10. Can that be a problem of me not getting any 220v at the output of the transformer?
