SHORT DURATION PULSE GENERATOR




SHORT DURATION PULSE GENERATOR

IC 555 has been used in many many applications. It is up to you how you manipulate it.  I have designed this circuit for use in Inveverters.  When inverter trip due to over load.  The user comes under complete darkness and he /she needs a light source to locate inverter to reset it.  This is a very awkward situation,  to avoid this I have designed this circuit.  If inverter tripped due to overload it will reset the power after every 4-5 seconds indicating inverter is overloaded, thus user can reduce the load and inverter works fine.

It is simple multi vibrator circuit producing positive going short duration pulses with a gap of 4-5 seconds.  LED L6 gives visual indication of pulses.  Positive going pulses are available at pin3 of IC3 and negative going pulses are available at collector of transistor Q9, one can use these pulses as per circuit requirement.

  1. Your blog is so beautiful.
    I am very much impressed with the neatness and most charming look and the way you write the posts.
    May I ask you one thing, that with which particular software, do you draw these circuit diagrams...?
    I have been using Corel-5 for circuit drawing since long on my site http://vsagar.com, (on which you recently put your comment), but the circuits quite long to draw and then publish them on this site.
    If you want to share these details of drawing circuits, please give your valuable feedback.
    Thanks.
    And wish you best of luck in your future endeavor...
