Simple low power Inverter Circuit (12V DC to 230V or 110V AC) diagram using CD4047 and IRFZ44 power MOSFET

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. 😉

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)

Hi GAURAV,
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.

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.

Hi Anand,
Nice to see you here. Yes 10A transformer can be used for operating the above mentioned things. With 12V,9Ah battery it can operate for less than 1 hour.

We have replaced the pot with resistors for simplicity and to reduce the cost.

Thank you very much,

[email protected]’adminOctober 17, 2013 at 11:53 am
Hi,
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.

Hi hardik
It will reduce efficiency, base current of these power transistors are high so it require extra driving transistors.

hello sir,
i assembled the circuit on a breadboard and got the required output of 12v ac near the primary of transformer. but when i connect the transformer with the load i am getting the voltage of 70v. why does the voltage decrease when connected to the load?

Hi Rfiz
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
i used a transformer of current rating 2A and the load that i connected was a 15w bulb. Why did the voltage reduce to 70v on the secondary side of the transformer?

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

Hi Sanaullah
Drain ans sours are short and use separate resistors for gates of each MOSFETs.

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 ??

Use 6-0-6/10A transformer to get 60W output.

Hi,
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).
Thank you!

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!
