This is inverter circuit 500W output. It will convert 12VDC to 220V 50Hz. You can build it easily and inexpensively. Friends favorite this. 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 Watts. It is a good size. Use with television receivers and light bulbs as well.
How it works
When looking for the circuit. I get headaches. If you are a beginner or I cannot buy expensive good quality circuits. Requires only one transistor. Or if you have free time. I want to build an 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 an 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 these projects.
If you need 500 watts output. 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 a day about 5 hours.
So you need current from the solar is (45A/5hour = 9A)
or 9A x 18V = 160 watts.
Learn other Inverter circuits
Is it difficult for you? Let’s see an easy circuit better.
Make 555 Inverter circuit
Do you want to learn a simple inverter circuit? The output is about 50 watts. And using a few parts and a small circuit.
Here is an IC 555 inverter circuit. Because of using 555 timer and MOSFET as main. I experiment it to work well.
DC to AC Converter circuit
Using CD4047 and MOSFET, transistors output max 60 watts
This way is easy to make, small.
The 12 volts of a Car battery and converted to AC 220V 60 watts. Then apply to appliances easily. And portability easy with Because of the small. In-circuit we use CD4047 and BD249 as the main part so is a mini circuit.
How to make simple inverter circuit diagram within 5 minutes
In the two Circuit diagram below, just use 2 transistor, 2 resistors, and one transformer only. They can convert 12VDC from battery to 220VAC or 120VAC to apply small light bulbs or lamps max 10 watts.
Also 500W inverter circuit for you
If you think that This circuit is not good enough. For your work. It is hard to find equipment. You do not have it now. These circuits may be viewed below. It may be appropriate for you.
1. Inverter 500W 12V to 220V By IC 4047+2N3055
Using this circuit you can convert the 12V dc in to the 220V Ac. In this
circuit 4047 is use to generate the square wave of 50hz and amplify the
current and then amplify the voltage by using the step transformer.
How to calculate transformer rating
The basic formula is P=VI and between input output of the
transformer we have
Power input = Power output
For example if we want a 220W output at 220V then we need 1A at the output.
Then at the input we must have at least 18.3V at 12V because: 12V*18.3 =
220v*1
So you have to wind the step up transformer 12v to 220v but input winding
must be capable to bear 20A.
2. 500 watts MOSFET power inverter circuit
As 200 watts inverter circuit. We use Q1, Q2 is the mosfet acts as a power output. That can withstand currents up to 18A. According to properties listed in the table of Figure 2. If the circuit is fully functional with maximum power of 12V x 18A = 216 watts. But in practice, the circuit should work up, it may be damaged. Therefore, it is designed to operate up to 200 watts.
Since we want the current more than 40A. But the power mosfet single, able to withstand current is 18A, therefore have to be 3 pcs. And When designing a circuit in a push-pull model thus requires a power mosfet 3 pairs.
We have the output current up to 54A which can withstand more demanding than 14A. It is good for the operation of the circuit. Because each power mosfet will not be overburdened. And the heat of the mosfet least, the lifetime of the life circuit.
Then see circuit diagram below:

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 https://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
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.
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..
My mistake the RX should be 10 watt 0.1ohms i just corrected it..peace
admin,
thanks 😀
@seen You welcome I am not good electronics.
I like collect electronic circuits only.
can you give a lil explaination of 100ohm 1/4watt? can i use 100ohw 5watt instead?
Junrev, have u finished with your simulation? is the output produces 220VAC?
@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
@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..
@junrev you using transformer cnter tap 500VA??
@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..
@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…

How can i made 1000wats inverter?
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.

i mean the output secondary of the transformer have 12v 0 12v?
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?
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.
Please any body with 400watt or 300watt inverter circuit should please send me the link or send the diagram through this email [email protected]

Hi Andrew,
I think you can try it. 2N3055 have ICE current about 15A max. (normal 3A). But 2SC1061 have ICE about 4A max or 1A normal. You may use more 2SC1061 transistors. If you have them.
