# Make Simple 555 Inverter circuit using MOSFET

Last updated on April 16th, 2022 at 09:58 am

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.

When use source is 12V battery will have the output of 220V AC 50Hz.

## The principle of the circuit

I think many peoples do not like to read many words or long reading.

Firstly, DC voltage from a battery gets into square wave oscillator circuit. It produces AC voltage, 50Hz frequency.  But this is too low current.

Recommended: How does NE555 timer circuit works

What can you do? Use the power switchings such as the power transistors or MOSFETs.

But AC voltage still is 12V.   Next, Transformer inductance voltage to rises into 220V AC 50Hz to apply load.

### How 555 inverter circuit works

In the circuit above is completely circuit diagram of this project. I use IC-NE555 timer is a square wave frequency generator output of 50Hz.

The frequency is determined with R2-resistor and C1-capacitor.

### Output 555 Frequency Calculation

If you use R2 is 150K. It is 47HZ output. You may use a potentiometer-50K in series with R2. To adjust a frequency is 50HZ

MF4Me said:
“By calculation (results will vary depending on component tolerances) a good combo of common parts would be:

• 0.2 uf (2 x 0.1 in parallel)
• 100 Ohm for R1
• 72K (39K and 33K in series) for R2.

That calculates to 50.069 Hz with a 50.03 duty cycle.

That is smart accuracy. If your tolerances work out.

What is more?

Then, we use both N-type MOSFET, IRF540 (Q2, Q3) to drive a transformer coil (primary winding).

The output current at Pin 3 of IC1 will flow two ways.

• First, through R3 to a gate of Q2.
• Second, flows to Q1-transistor BC549 as inverter logic form to reverse signal difference first ways.

Next, the current flows to the gate of Q3 to also drive the transformer.

It inductance low AC voltage to high volts, about 220V to 250V.  According to the condition of the battery, 12V to 14.4V.

The circuit diagram of MOSFET Inverter

The transformer I use 2A current and 12V input at output power more than 100 watts.

Here are a few related posts you may find helpful, too:

### Why use MOSFET?

In circuit use IRF540 MOSFET. There are many reasons to use them.

1.  It is easy to use.  They do not need the pre-drive transistor in Darlington is the same as normal transistors, such as TIP41, 2SC1061 etc.
2. It can drive high current to load, 27A max.  While the transistor (TIP41) can drive load 4A max.
3.  It is inexpensive just 0.5US only.
4. The body is TO-220 looks like TIP41 transistor so easy to mount on a heatsink.
5. They can use smaller heatsink than a transistor, they are not too heat.

#### The component list

IC1: NE555 timer IC = 1 pcs.
Q1: BC549-NPN 40V 0.5A transistors = 1 pcs.
Q2, Q3: IRF540-N CHANNEL POWER MOSFET, 100V, 27A, TO-220; 2 pcs.
C1,C2: 0.1uF 100V mylar capacitors = 2 pcs.
0.5W resistor
R1: 4.7K = 1 pcs.
R2: 120K = 1 pcs.
R3,R4: 1K = 2 pcs.
R5: 5.6K = 1 pcs.
T1: 2A 12V__CT__12V transformer = 1 pcs.
Heatsink

### Building and testing of 555 inverter circuit using MOSFET

This projects I assemble components on a universal PCB board. As Figure 2, while it operated will get little hot. So use enough heatsink.

Figure 2

Then, check the circuit for error. Please watch the video below.

### When checking all no error

We will test it with 100 watts lamp at the output. Then, apply 12V battery source. You will see that. The lamp glows. But the battery voltage is slightly low. Also, the AC voltage output is 190V.

After that, We check waveform is a square wave as shown on the scope.

Note:
Some people wonder about something. I will share with you.

The electrolytic capacitors are 470uF 50V. I put it to filter a smooth current. It does not need. If you use a 12V battery, 10Ah. Because it is a stable power current source.

Ideally, if you need full 100 watts output. You need to use 8A transformer. Because of input watts = output watts = 100 watts.

When the primary coil voltage of the transformer is 12V at 100 watts.
The output current input = 100W/12V = 8A (approximately)

If it not working
I feel uneasy if you build this project It does not work.

First, you need to review well, the pin of the IC, resistors, capacitors. And the important is connecting the MOSFET.

Second, should do not connect the power cord to the transformer and MOSFET.

Third, check the 555 timers working, frequency generators at pin 3 first. You may use a voltmeter to measure a voltage across pin 3 and ground. You use surely oscilloscope to watch waveform.

20. Hi,ErHonni.

Yes, you can use potentiometer for adjust output frequency.

21. Hi,RK Chall.

22. Hi,Mark.

23. Hi,Francisco Mateu… My friend

24. Hi,serunkuma shem

25. Hi,Elijah

The output is square wave at around 50HZ-60HZ
You may use potentiomer for adjust frequency.

26. i can’t find irf540 please tell me the alternative of irf540..

27. @sk sahabaj.
IRF540 is N channel MOSFET that you can you any Mosfet which high current and voltage 33A 100V. I like it because very cheaper and easy to buy.

28. v

hi what can i do to increase the out put power to 200w

29. Hi,V
You can add Mosfet in parallel to increase current driver transformer which must change is 2 times current.

30. v

hi admin thank u very much for your replay ,can u tell me how to add mosfets in parallel

31. Hi, V
You can add mosfets in parallel for increase current drive secondary coil of transformer.

32. vasudev

do you think adding mosfets will increase the output power effectively

33. Hi,vasudev
For me if add mosfet in parallel it will increase current to higher.
I should this mosfet because cheaper and easy to buy.

34. vasudev

hi momename
can i use ne556 instead of ne555,because it is more efficient than ne555

35. vasudev

hi sorry it is not ne556 it is ne7555 which is cosmos ic

36. @vasudev
Yes you can use NE7555 same NE555.

37. vasudev

hi according to the power relation p=i*v ,where i is current & v is voltage
but here if we use 12-ct-12v 2amps transformer we get only 24w of output how can we get 100watts of output power (p=2amp*12volts
=24watts) ???

38. @vasudev
I do not very good any principles,But I love Electronic, If I test it works, I will tell you.

39. > Hi good friends,i have a ups with 24v battery and wont to convert it to
> inventer to power my 110v fridge thank you.
>

Hi, James Abeaku okine
I not have a 12V to 110V inverter circuit example show you.
If you have free time you may be test your ups circuit.
and modify them.

or you may remove the transformer.
To adapt circuit into this circuit https://www.eleccircuit.com/220-volts-power-inverter-using-ne555-and-mosfet/

But you must to use zener diode or IC7812 to reduce voltage of 24V battery to 12V to supply the IC555 only.

I am sorry for circuit ideas (in image form) since now I take my family to weekend Holiday.

Thanks

40. vasudev

hi momename does the increase in gate current increases the output power

41. Charles

I have made d circuit and every thing is ok…but when i put the +ve terminal its sparks and flash the 220V 20W bulb while one of the mosfets becomes very very hot and starts smoking.

Pls help ….thanks

42. Charles

In the picture on the website, you used an electrolytic capacitor…?

43. Hi,vasudev
You may increase current drive transformer with add mosfet next one in parallel.

44. Hi,Charles.

45. hai momename
can we use it for fan in home?

46. ayman

what will be the output if i connect 12v/ 70AH
and i need ahelp for making an 1500W inverter

47. saurabh

please tall me meaning of ct

48. saurabh

Work but 60 watt bulb is very dim not full

49. Hi,saurabh
If you need full watt ouput.
You must use 100W = 12V x I? transformer.
or 8.3A input transformer.

50. saurabh

Using 3 capasitor and what diagram of third capasitor

51. Mr.Surasak

what will be the output if i connect 12v/ 70AH
and i need ahelp for making an 1500W inverter

52. When battery is connected bc549 getting hot no out put voltage solution pls.

53. Kingshuk

Hi momename, if iput more mosfet in parralal can it increase wattege my requerement is 800w

54. Hi,saurabh
The third capacitor is filter for low current battery.
We not need put in the circuit.

55. Hi,Mr.Surasak
Thanks for visit.
If you want fully power 1500w.
You need to use 125A too current for me.
and this circuit is square wave ouput.

56. Hi,Kingshuk
Yes, If you connecte more mosfet in parrallel it can drive very many current load.

57. Anjan Chatterjee

Hi Momename
If I connect the 8.3A transformer, then should I increase the no. of mosfet, or may I use the 8.3A 12V 100w transformer with the same circuit. Pls let me know ASAP..

58. Hi,Anjan Chatterjee
Thanks for visit.
Ideally, the mosfet can drive 27A maximum.
But we may connect them in parallel x4 pcs.
Normal current each mosfet is 2A so easy to drive load.

59. Anjan Chatterjee

Thanks for your kind feedback Momename. I actually want to use this circuit as a travelling battery charger(phone, dslr)where I connect solar panel (12V, 70-80watt) as source. I will connect the battery charger as load, I think the charger don’t get to much watt. So I think I easily use this circuit. **Pls correct me If I am wrong..
Thanks..
*should I send My photo or the mentioned project photo ?

60. Anjan Chatterjee

Hi momename
Thanks for your feedback..I previously checked that project. But I don’t want to carry the battery. I thought I simply connect the 12v 7-8ah solar panel directly with your this circuit(source). If I do so then will the circuit work ? I dont need power at night.
Thanks A lot for helping me…

61. Anjan Chatterjee

Hi In your circuit diagram you mention Two +12 volt Dc Terminal/Point. But In your Figure 2 You put Providing +12 Volt Dc Only one Point. Can You Pls Tell Me Is The Diagram Right ? Should I provide +12 in both terminal or should I Provide +12V in one & another with -12V. And Pls also mention the points where I have to provide The +/-12 Volt in the circuit.
Thanks..

62. Saikat

In place of bc549 transistor can I use bc547 ???

63. Hi,Salkat
Yes,you can use it BC547 same BC549 or similar: BC550,BC546, etc.

64. Hi,Anjan Chatterjee
In Figure circuit diagram.
All ground is (-12V terminal)
All +12V are joint together = +12V.

65. saikat

If i use 8 amp of transformer then i have to use 2 pair of mosfet?

68. Hi,Saikat,
Yes, you can.

69. Hi,prits
If you ue transistor, you should too many transistors.
In this case you may use darington transistors.

iam very happy with this, but sir the two types of the inverters i make them no any problem but sir they can’t take RED Globe.plc sir can we start communicating in other to help me with some or many ideas thanks so much (+2347064396921)

94. akshay

sir you dont mension the capacitor at the battery terminal side and it is very important one ,so i got the output correctly .

95. Dies ist eine wirklich interessante Schaltung. Sie sollten diese zum PATENT anmelden. Der Wirkungsgrad von mehr als 400 Prozent ist wirklich bemerkenswert. ‘The transformer I use 2A current and 12V input at output power more than 100 watts.’
Erreichen Sie diesen hohen Wirkungsgrad durch die unsymmetrische Ansteuerung des Transformators?
Ich habe da einen Vorschlag für Sie. Erzeugen Sie aus den 220V wieder die 12V Speisespannung. Sie haben dann noch genug Energie über, die Sie weiter verwenden können. Gehen Sie aber sicher, daß Sie alle überschüssige Energie entnehmen. Ansonsten könnte ihnen die Schaltung aufgrund des Energieüberschusses explodieren.
Viel Spaß, Baltuodis.

143. KUBENDHRAN A/L MUNESWARAN

Hi bro, I like the concept you use to design circuit. I fabricate the same circuit with the same spec of all the component as you used but instead of using 12-0-12 2A transformer, I choose to use 12-0-12 4A transformer. In software simulation, I have tried using Multisim and Proteus. Sorry to say the simulation was failed. The result in real time hardware fabrication is a positive. I manage to light up a bulb but the waveform generate from oscilloscope is clamping not a square wave. The light which lights up keeps flicker. I used 12v 7.2AH battery. Did you manage to simulate this circuit in software? If so, please reply me. Thank you.

150. Aerk

You project and website are very good and benefit for Electronic working.

• Hi Aerk

151. Friend kaj holona to

152. Please can I use ups transformer?

• Yes you can use it.

153. MF4Me

Dude, either your cap is way out of tolerance or your math is off. A 4.7K resistor for R1 results in 58.97 Hz by calculation. If peeps are putting 60 Hz into a 50 Hz transformer, they’ll have problems.

• Hi MF4Me,
Thank for your feedback. You are correct.
We can change R2 too. To set output is 50Hz.

• MF4Me

YW. By calculation (results will vary depending on component tolerances) a good combo of common parts would be 0.2 uf (2 x 0.1 in parallel), 100 Ohm for R1 and 72K (39K and 33K in series) for R2. That calculates to 50.069 Hz with a 50.03 duty cycle. That’s smart bomb accuracy if your tolerances work out. Otherwise that should get folks close enough.

• Wow! that’s nice. You are great.
Your design and calculations are excellent.
Thank you very much. It is will definitely benefit everyone.

Kya ya battery ko charge bhi KR sakta hai

• Hello Rahul,
Thank you for visiting. You mean you use this circuit with your mobile battery charger again, right?

It may work. But…It is better. If you use 12V to 5V DC converter to charger the mobile directly.
See: https://www.eleccircuit.com/12v-to-5v-converter-step-down-3a-regulator/

Hope I will understand it correctly. If you finish this project do not forget to share me know too.

155. Can it work with a non-centre tap transformer

• Hi Emmanuel

No, you cannot use for non-center tap transformer.

Hi,
Can i use sw50n06 instead of irf540 ?
i tried, but it’s getting heated unexpectedly.

• Hi,
Yes, you can I just read datasheet of SW50N06: on TO-220
FeaturesN-Channel MOSFETBVDSS (Minimum)RDS(ON) (Maximum)IDQg (Typical)PD (@TC=25 ): 60 V: 0.023ohm: 50 A: 30 nc: 130 W

You may try it. Please cheack leg it again. I sure you can do it.

Hii, i have one doubt that this circuit output is 50hz sinusoidal or sqare wave? Please help me solve this problem, as i also wanted to charge my mobile phone using this and mobile charger required only sinusoidal input.
Thanks and regards

Sir this circuit output is 50Hz sinosoidal or sqare wave.

• Hello Rishikesh Singh,
I am happy that you feel interested in this circuit. Its’ output is a square wave.

Thanks
