Pure Sine Wave Inverter, Using IC 555

The proposed IC 555 based pure sine wave inverter circuit generates accurately spaced PWM pulses which imitates a sine wave very closely and thus can be considered as good as its sine wave counter part design.

Here we use  two stages for creating the required  PWM pulses, the stage comprising the ICs 741 and the other comprising the IC 555. Let’s learn the whole concept in details.

How the Circuit Functions – The PWM Stage



PWM pure sine wave processor stage using opamps and IC 555



The circuit diagram can be understood with the following points:

The two op amps are basically arranged to generate the required sample source voltages for the IC 555.
The couple of outputs from this stage is responsible for the generation of square waves and triangular waves.

The second stage which is actually the heart of the circuit consists of the IC 555. Here the IC is wired in a monostable mode with the square waves from the op amp stage applied to its trigger pin #2 and the triangular waves applied to its control voltage pin # 5.

The square wave input triggers the monostable to generate a chain of pulses at the output where as the triangular signal modulates the width of this output square wave pulses.

The output from the IC 555 now follows the “instructions” from the op amp stage and optimizes its output in response to the two input signals, producing the sine equivalent PWM pulses.

Now it’s just a matter of appropriately feeding the PWM pulses to the output stages of an inverter consisting of the output devices, the transformer and the battery.

Integrating PWM with the Output Stage

The above PWM output is applied to the output stage as shown in the figure.

Transistors T1 and T2 receive the PWM pulses at their bases and switch the battery voltage into the transformer winding according to the duty cycles of the PWM optimized waveform.

The other two transistors make sure that the conduction of T1 and T2 takes place in tandem, that is alternately so tat the output o from the transformer generates one complete AC cycle with the two halves of the PWM pulses.

  1. Dear brother ,
    how can we convert the same circuit for high power rating like if we want to make it for 5KVA or 10KVA what changes should be made??

    ReplyDelete
  2. Dear Engr,

    you can do it by replacing T1/T2 with mosfets and by using an appropriately rated trafoand batery

    ReplyDelete
  3. Sir could u plz tell me how to measure frequency using a Normal digital meter

    ReplyDelete
  4. you can measure frequency only if your meter has this facility.

    check for a small horizontal "S" or "Khz" indicated on the dial, use this range for measuring Freq

    ReplyDelete
  5. A horizontal S ( as you said ) resembling a square wave is there in my multimeter. But when i am connecting the leads b/w secondary terminals of a 15 V ac transformer no readings is showing on putting this range. I think the transformer doesn't change the input frequency since it is a power transformet..... Is my way of taking frequency reading is ok sir ???'

    ReplyDelete
  6. yes it's the square wave symbol which is assigned for measuring frequency.
    The transformer secondary should definitely show a 50Hz frequency on the meter when the above range is selected.

    Your meter frequency range could be faulty or the prods are not making contact.

    ReplyDelete
  7. T6 switches T1/T2 simultaneously with the PWM pulses, while T3/T4 make sure that T1/T2 conduct alternately at 50Hz rate individually (100 times per second together alternately), it's as simple as that.

  8. It is very interesting the idea of different inverter design from your blog.
    I have following some doubts
    1). What may be the specifications of the battery ( Ah and V ) being used with a 300 W transformer to support a maximum load of 300 W ?
    2). Can you please point out a modification to any pwm inverter like this to facilitate the feature of automatic load regulation. I found a similar one in your article (posted 6 days before ), but didn't seem like satisfying the requirement.
    1.bp.blogspot.com/-bco7IGMHtdw/T7CrBQp-7tI/AAAAAAAABWE/jO4rB9DRcpU/s320/output+controlled+inverter+circuit.png

    I think it only shutts off the ac out when the voltage rises a specified limit (say 230 V ). It doesn't stabilize the voltage at 230V at varying loads.

    ReplyDelete
  9. Thanks Arun.

    300 watts usage would mean 300 watt consumption in one hour. so if you intend to use this operation for say 3 hours, then 3x300 = 900wats, divide this by battery voltage(12V) gives 900/12 = 75, means the battery should be 75AH rated but practically you would need above 100AH battery.

    For voltage regulation you can refer to this post:

    https://homemade-circuits.com/2014/01/automatic-output-voltage-regulator.html

    ReplyDelete
  10. Sir If i am gonna construct a PWM type of inverter, i have to use 24 V instead of 12 V along with a 230V/12-0-12 V transformer. Am i right ?
    I am using the series configuration of two 12 V battery banks each of which is a parallel configuration of two 12 V 20 Ah sealed lead accid batteries, thereby getting an overall specification of 24V 40 Ah.
    Now my second question is whethet this will be enough to support the required load, since by calculation Ah=900/24 =37.5 ?
    I think it will support atleast 250W for the same time period.

    ReplyDelete
  11. Arun, increasing voltage will decrease the current requirement of the inveter, this the only advantage of using higher voltage trafo and batt, it has no connection with a PWM type or any ordinary design, you can incorporate higher voltage concept in any design.....however for full bride designs you will require a single winding while for center tapped you will require a center tapped trafo.

    making series batery connections will not yield double AH, the AH will stick to 20AH only.

  14. Hi Bro, how are you? Hope you and your family all going well.

    I am preparing to build this inverter (the 3’rd one after succeeding builder the 400 Watts inverter design circuit from your other post and the 1 KVA H-bridge with 4 N Channels mosfets).

    Before I starting to build this one, could you please advise me to the following questions:
    1. What is the closest value of the resistor + preset P1 to achieve the best amplitude setting; if I substitute it’s with 220K preset instead of 10K resistor + 1M preset as of your design (I have no 1M preset ready in hand). I still not own oscillator/frequency meter, so it would be helpful for me also if you can give me some indicator of voltage measurement at some important points.
    2. I want replace the BDY29 with IRF3205 N-Channel mosfets and feed the gates voltage with 18 Volts supply line from an additional voltage doubling stage. So the TIP127 and TIP 122 can be replaced with ordinary small transistors such as BC547 and BC557 accordingly. I think doing this would become much more efficient. Do you think it’s could make sense?
    3. Can I use 741 OpAmps instead of TL072?

    Thanks a lot for your support.

    Best regards,
    Ferry

    ReplyDelete
  15. Hi Bro,great to hear from you back!

    According to me all that you have asked makes sense.

    Use IRF540 instead as these would be easier to obtain.

    for the opamps you can use two opamps from the IC LM324, will be much suitable.

    I am not sure about the preset set up values you will have to check them out through practical assessments.

    Do everything extremely carefully and step wise only that could lead you to success.

    ReplyDelete
  16. Thanks for your fast response Bro,

    I think I’ll postpone building this project, since without any parameter measurements at some important points and without oscilloscope is difficult for me to achieve the correct results, especially to your unusual design like this.
    My understanding to your design is that you use the first OpAmps for astable-multivibrator which output (square wave) to be fed to the second OpAmps which is designed as Integrator, from where the triangular waveform output will be used to superimpose or chops the PWM output of the 555 IC.
    Could you please explain me why you fed back this triangular output to the 1’st OpAmps also?

    From your expert views, Is it possible to convert a sinewave produced from a Bubba oscillator or any other oscillator stage, which output swing at about +20 Volts and -20 Volts and frequency of about 50-60 HZ, which directly fed to flip-flop switch the NPN and PNP power transistors alternately without any driver IC?

    Thanks Bro, I have learned a lot from you.
    Best regards,
    Ferry

    ReplyDelete
  17. Hi Bro, sorry me again.

    Actually I have build the driver stage tomorrow with 500K variable resistor for adjusting the amplitude that I borrowed from my other finish project.
    First I just connected the 10K resistor with it and measured the output of pin 2 from IC 555. Then I add another 510K resistor to the other end of potentio and measured again these output. But I could not sensed any fluctuated swing although the frequency preset (I used 220K preset instead of 150K) has been varied from zero to max. The voltage coming out from IC 555 pin 2 was at about 7 to 8 Volts, while at pin 3 vary from 4.5 Volts to 9.5 volts (with various preset setting).

    Regards, Ferry

    ReplyDelete
  18. Hi Bro,

    The opamp circuit is a standard design which I borrowed from the datasheet of the opamp, so I cannot say much about its configuration, it must be correct since it's designed by the experts.

    BJTs or mosfets will never respond to sine waves directly, because each counterpart will swing to the highest voltage as soon as the saturation limit is reached which will result in a square wave output from the devices, and not sine wave.

    Again I would say that without an oscilloscope it would extremely difficult to judge whether the circuit's producing the correct required outputs, so I think an oscilloscope is a must for a design as complex as the above one.

    ReplyDelete
  19. Thanks for your reply Bro, I agreed with you. I'll take a break with this project.
    Btw, I read your other post of inverter circuit using 556 IC, I'll study it first and read your discussion with other readers about all aspects that might be encountered while building this. See you there in the near next days.

    ReplyDelete
  34. Dear Omar, you cannot just make any circuit directly and entirely as it is shown and hope for success. That's not the way to go.

    You will need to make each stage separately, check it separately and then proceed identically for the the remaining stages also.

    The above circuit may have some minor faults which can be easily traced and rectified.

    Did you check and confirm the frequency generating stages separately with an oscilloscope???

    Did you check the output stages separately?

    Proceed in the above manner you will definitely find the circuit working.

    Am ever grateful for your dedication to all electronic hobbyist around the world.
    Engineer , my pure sine wave inverter i built is perfectly working , but still i need to be well versed about the following points :
    1)How to measure or between which two points should read 200HZ and 500HZ
    2) My oscillator outputs is between 8 to 9v AC when 12.8 dc is applied at the input is this ok? And what is the suppose voltage in particular for this case?
    3) What is the transformer output(secondary coil)
    I will be grateful to receive a feedback from you thanks.

    ReplyDelete
  40. Dear Kaluya, thanks!

    The oscillator output voltage should read 50% of the supply due to 50% duty cycle, for 12.8V supply it should show around 6,4V

    The transformer output will be as per your requirement, 120V or 220V

    pls provide me the link of the design you have built.

    ReplyDelete
  48. ok then. here is what i think.

    from my understanding of inverter operation, there is a unit to create d alternating pulses from a dc source, den this signal is fed to a tx for amplification to d desired voltage level....now d unit that creates this pulses determines if its a pure sinewave or modified or even square wave inverter.

    What if a true sinewave motor(mini ac generator) is used to produce this signal and then this sinwave signal is used to switch some power mosfets appropriately wouldn't that be a better way of producing a pure sinwave inverter?

    are my assumptions practical? shed some light on this please.

    thanks.

    I just only find 0.33 in value of 5 watt.
    Can i replace it with these 0.33?

    2nd. can i replace the T1 an T2 by 2N3055 and what value that i'll get in wattage?

  67. Hi Fadly,

    you can use 3nos of 100 ohm 2 watt in parallel for achieving the 33 ohm value...I hope 100 ohm/2 watt or 3 watt will be easily available in your area, yes T1/T2 can be replaced with 2N3055

    the base resistor can be the same, that is 33 ohm, if more power is required then you could reduce them a bit more to 22 ohms or 20 ohms.

    In my home i have only a trafo 12-0-12 at 3 amps, and a battery 12v 5 amps.
    Can i try it circuit by using them?

    I hope you don't bored by my questions, sir. :)

    ReplyDelete
  73. I appreciate it but sorry that's not the right way to proceed, you should build the various stages first and confirm them using proper test equipment.

    first test whether the opamps are generating the intended waveforms or not, then check the 555 response to these waveforms.

    once these are confirmed then you can integrate the relevant inputs with your power transistor stage....and do more related tests before going for the final results

  80. If I may ask..... saying that your true ac motor would be the best choice to create pure sinewave, how would you get the motor to spin to create electricity?

    If its an off grid system then no electricity would be present and a motor requires electricity to produce electrical motion.

    If you plan to use a mini generator that requires mechanical motion (spinning) to create electricity which leaves the question how would you get it to spin?

    ReplyDelete
  81. Not an AC motor, a DC motor would be required for making the sample sine generator....the battery can be used for spinning the motor...
