This simple low power dc to ac inverter (dc to ac converter) circuit converts 12V DC to 230V or 110V AC. By doing simple modification you can also convert 6V DC to 230V AC or 110V AC. It can be used as inverters for home needs to enable light loads (electric bulb, CFL, etc) at the time of electricity failure.
You can construct this circuit of simple inverter at a cheap rate with locally available components. Use a 12V rechargeable battery and battery charging circuit for this dc to ac inverter. We have already posted the circuit for battery charger.
Don’t forget to watch the demonstration video at the bottom of this article. I also recommend you to have a look into our latest SG3525 based inverter schematic.

Working of DC to AC Inverter
You must use a battery and battery charger to implement this inverter circuit. Battery charging circuit is described in our previous post.
The inverter circuit is built around IC CD4047 which is wired as astable multivibrator.
The operating frequency of astable multivibrator is set to 50Hz.
The power MOSFETs IRFZ44 are directly driven by the Q and Q’ output of CD4047.
The power MOSFETs are connected in Push Pull configuration (Power amplifier). The MOSFETs will switch according to the pulse from CD4047 astable multivibrator.
Must Read: MOSFET working: Animation with Java applet simulation
Thus an AC voltage is transferred to the primary of transformer; it is stepped up to 230V.
The transformer used here is an ordinary step down transformer which is connected in inverted manner. That is, the primary of a 230V to 12V-0-12V step down transformer can be treated as secondary for this inverter project.
If you would like to get 110V AC, choose 110V to 12V-0-12V step down transformer in reversed way. (That is primary as secondary and secondary as primary)
The inverter output is filtered by capacitor C2.
Use suitable heat sinks for MOSFETs.
Here is the tested and verified inverter circuit that I have made, for those who doubt working of the circuit. 😉

if i connect the secondary wires of the transformer to the alternating current what will happen by plugin does the battery get automatically charged or not?
[email protected]’YaseenJuly 17, 2013 at 7:10 pm
No,it not possible to do so, you have to connect separate charger circuit for it, it may damage your circuit.

[email protected]’AnonymousJune 24, 2013 at 8:29 am
I want to build this circuit for a simple application – to drive a small aerator for an extenal fishpond. Later, I will then add a small solar panel.
When sourcing the resistors I came across a puzzle. Surely, the resistance is a property of the device independant of the voltage rating (within limits). When trying to source the variable resistor (trimmer or potentiometer) one of the specifications is the wattage rating. None of them that I have seen allow a 22k ohm resistance at 12 Volts. Am I being too clever (knowing Ohm’s Law)
[email protected]’GAURAVJuly 15, 2013 at 12:26 pm
i am GAURAV SHETA. this circuit how many watt withstand?? and how many prize of this circuit??
[email protected]’AdminJuly 15, 2013 at 6:25 pm
This circuit can handle 150 watts if 12.5A transformer is used.
The circuit cost around Rs.190 without transformer. With 5A transformer it can handle 60 Watts.
[email protected]’Anindita RoySeptember 10, 2015 at 11:33 am
This is Anindita Roy. I am not an electronics person…rather from mechanical engineering field. I want to make such an inverter for powering a desktop PC. Will it work? What capacity transformer will be needed? Are such inverters available in the market?

Hi Anindita Roy
Use low cost UPS, it need 300W.

hi admin will the reverse of the transformer not burn the winding?
[email protected]’AdminJuly 18, 2013 at 6:50 pm
It will not burn the winding as output of the inverter is 12V AC.

[email protected]’jithuJuly 26, 2013 at 3:56 am
sir,,is overload affect the circuit?
[email protected]’AdminJuly 28, 2013 at 6:43 pm
Overload will damage the MOSFET and it may get burst. As per the above circuit diagram, it can handle only upto 60 watts load. It can be increased upto a maximum of 150 watts if 12.5A transformer is used.
[email protected]’AnthonyNovember 16, 2015 at 7:54 am

How do I have to connect the output to obtain 12 volts AC?
Can I obtain 3 volts AC by charging the circuit with 3 volts DC?
The same for 16 volts? What would the range limits be?
Thank you very much,
[email protected]’adminOctober 17, 2013 at 11:53 am
1)To obtain 12 volts AC, take output from Vcc and either of the drains of power mosfet after connecting transformer.
2)Yes you can get 3volts AC like that.
3)Min 3V and max 18 V
But keep care to use exact matching transformers accordingly.
[email protected]’MalvikaOctober 14, 2013 at 7:16 am
If the gate input to both mosfets is high, wont it short circuit the primary end of the transformer??

YaseenMarch 22, 2014 at 2:11 pm
You must use transformer of current ratting >5A and connect load of 60watt maximum, to increase power use high current transformers.
[email protected]’rfizMarch 24, 2014 at 5:04 pm

YaseenApril 10, 2014 at 4:25 am
It is due to low current capacity of the transformer.

can I use 12v car battery to this inverter circuit?
[email protected]’Areeb AhmedMay 10, 2014 at 9:54 am
Hello Sir, I have just bought the required components of above circuits 🙂
But I have doubt will it work or not ,
I have bought Transformer 12-0-12 V with 2 amp for Inverter, and separately bought a transformer of 15-0-15 V with 1 amp stands. Will it work ?
I want to know that the purpose of Potentiometer in Charger ??? What does it purpose ??

Can i build this circuit in any software?? I tried in multisim but i cant find CD4047 ic anywhere. Can you tell me in which software i can find ic CD4047. Please i need this badly..
[email protected]’Areeb AhmedMay 11, 2014 at 5:38 pm
I am connecting the multimeter terminals to the battery while charging but buzzer doesn’t stop beeping and LED not glowing but while charging the terminals of the battery it is giving 12.4 v (charging in progress) and potentiometer doesn’t take any effect not even output voltage effect kindly help me.
i am using 12V 30amp battery and transformer rating 15-0-15 (1 amp)

if i want to use 6V battery what other modifications will i need to do, other than changing the transformer to one with a 6V secondary,
YaseenMay 20, 2014 at 1:01 pm
Use 6-0-6/10A transformer to get 60W output.
[email protected]’RAVIKUMARMay 13, 2014 at 6:02 pm
circuit is not working
[email protected]’RAVIKUMARMay 16, 2014 at 12:29 pm
I do it but Ic is heated .What’s that reason
[email protected]’Aldo teranMay 21, 2014 at 1:54 pm
First of all, thank you for the circuit. I wish to know what should I do with my circuit so I can receive 110Vac – 100W at the output of the inverter. Should I add more mosfets? Or should I change the transformer? Which option is cheaper? I am using a car battery (12v and about 50Ah).

Sir can i use 6v 4.5ah battery?what changes to be done in the circuit by using 6v 4.5ah battery?how much output can i get using 6v 4.5ah battery?
[email protected]’vasudevJune 7, 2014 at 3:39 pm
yes u can use but output power and time duration will decrease
[email protected]’yogendraMay 28, 2014 at 6:23 pm
i am yogendra. I have made that circuit on breadboard. Initially circuit is working well but after some time later when i restarts circuit this is not working. Sir
Please give me suggestions.
[email protected]’vasudevJune 7, 2014 at 3:01 pm
what kind of battery u are using ,i mean i have handled this kind of problems before .i thing it is due to inrush current
[email protected]’vaibhav hayaranMay 29, 2014 at 4:51 pm
hi sir! can you please send me pcb layout of the circuit
[email protected]’sanjed arfinMay 31, 2014 at 7:51 pm
for which value of R1 , and R2 and c1 i will get 50HZ … how to calculate frequency for cd4947 ic’s …….. can i use irf540n mosfet
[email protected]’sumeshJune 1, 2014 at 3:03 pm
Hello sir iam sumesh i have made that circuit on bread board . Circuit is not working. Over heated ic and wire
[email protected]’yogendraJune 5, 2014 at 3:15 pm
Same problam happening with me. Admin plz reply
[email protected]’vasudevJune 7, 2014 at 3:37 pm
yogandra if u are using batteries with greater ah like 20ah or more ,the circuit posted above is sensitive to it because of inrush current wit damages gate terminal of mosfets .to avoid this their are many ways .if you are interested i will suggest you

Can i use this mosfets type(RF50N06) connected to make up to 500W inverter and with what transformer current rating
[email protected]’pritsJune 12, 2014 at 11:12 am
The above can be solved by using proper heatsink..yaseen help which parts should we heatsinked?? Reply fast
[email protected]’hishamJune 12, 2014 at 9:57 pm
i have 500 watt transformer (12-0-12/220v).i get it from burned inverter.
and i have irfz48…and ic cd4060.how to connect them to get the 500 watt.
[email protected]’Diglo1June 24, 2014 at 6:27 pm
Hello! I’m too putting this sircuit in use but i’m gonna make it last about 500 watts. The problem is that i have to use more mosfets, but how exactly do i put them in parallel (picture)? Does the load effect the frequiency while in use? Witch resistors does effect the frequency? And lastly how do i connect 12-230 transformer wich has no ground (12v mains two wires, 230 secondary two wires)? Thanks!
