Generator Mains Power Booster Circuit

Last Updated on February 17, 2018 by Admin 31 Comments

The post describes an alternator or generator power booster circuit, Let's find out more about the .

 

Generator Mains Power Booster Circuit
Circuit Justification

The circuit seems to be a straightforward AC voltage booster. The main part which can be to blame for providing the excess power is the high voltage capacitor C1 which charges up with each AC cycle and reverts the power by means of the switching triac into the linked load.

The load thus gets added power due to the switching high voltage capacitor by way of the triac.

The triac is usually a BTA41/600A, which replies and switches ON the moment the diac fires. The minimum voltage necessary for the diac to fire is around 30 volts.

The above idea may also be used with the following circuit which happens to be less complicated than the above and is also very much cheaper.

The capacitor ratings might be altered and tried as per the load, and individual choices.

However this circuit can be utilized only for heater applications such as irons, heaters, geysers, ovens, toasters, blowers, dryers, hot air gun etc.

About Admin

Hey friends, Thanks a bunch for stopping by this site! I am an engineer with a Bachelor of Engineering in Electronics and Telecommunication. One of my passions is gathering information from all sorts of electronics books and tutorials. I then take that information and compile it into a language that is super easy to understand. My goal is to make those complex electronics circuit concepts and technical terms much more accessible for all the new and budding electronics engineers out there. I can also design customized circuit diagrams as required by the users.
If you have any questions related to this field, please do not hesitate to drop a comment! I am always here and ready to help you out with any queries you might have. I cannot wait to hear from you!

    Please how many watts is the second circuit? I build it and is not working with my soldering iron not even to talk of iron Sir. Please I need an urgent help because this is my project topic and to be submitted soon. Thanks

      It is a tested design and it worked for me beautifully, my soldering iron became red hot within 1 minute.
      It is nothing but a simple voltage doubler circuit.
      310V x 50 mA = 15 watts

    The first circuit needs clearification
    OK I want to boost power from a 600watts generator to supply my electric iron and cooker what will be the rating of the diac

    The first one lacks clarity and unsure if it would work. The second one is a half-wave voltage doubler, DC output. When capacitance is small and load-current is large, the voltage will be unregulated, spiky, or contains more ripple.

      That’s exactly why the second circuit is recommended for resistive loads….

    I Made that second one its working, but i think the output was dc
    but the voltage was up to 250v.
    i have not test it with any appliances,
    please should i go ahead
    an test it?

      yes it will be DC but 2 times more than the input AC. You can use it with resistive loads sch heaters, soldering iron, and also for electronic items such as LED bulbs but only during mains brownouts.

    Hi admin, I connected the second circuit and when I measured the output voltage I onlg received a reading only for a second. I think the capacitor I sonly charging from just a half circle. I also tested the diodes and they were working perfectly. Pls what should I do

      check it with a 25 watt AC lamp and see the brightness…it will be a lot brighter compared to when it is connected to AC without this circuit..

      if you boost current, voltage will go down and vice versa

      you can use any triac and any diac as per your load specs…

      hello mordian, the first circuit was drawn from an obscure broken sample by one of the hobbyists, so we don’t know whether it was copied correctly or not, however the second circuit was tested OK, and could be used for boosting any AC resistive load, by appropriately dimensioning the capacitor values

    Pls can the first circuit be used to boost voltage for a big refrigerator which can’t just be powered by a small generator set

      Not sure. but most probably it cannot be used for inductive loads

      a 650 watt generator can be directly used for powering a refrigerator….why does it need to be boosted
