    Re: Booster converter Circuit

    hahahahaha true sir

    we wish we could discuss about this before we finalized the project

    We were way to far from reality


    Sir if someone asks your input is only 9V and output is less than that

    Then can u suggest an answer to reply them back?

    Re: Booster converter Circuit

    You could argue that 9V was only necessary to power the control circuits and they are relatively low power in themselves. It is true that if you could get enough power from the tree it would be possible to step the voltage up as you originally planned. The theory is good, the tree is the problem because it simply can't provide enough power to be usefully converted.

    It's better to share your questions and answers on Edaboard so we can all benefit from each others experiences.

    Re: Booster converter Circuit

    Sir you are super !!
    Thank you so much for helping me from the beginning!

    Next time when we plan a new project i will make sure i will first discuss it with you sir

    I will tell you about this project output tomorrow sir
    as we are going to wire it tomorrow

    Re: Booster converter Circuit

    Hello sir!!
    We performed the experiment and the following are the results

    From one tree:0.99V, 135mA
    like this we connected 3 trees in series and the overall voltage was 1.12V and 116mA

    And this we have given to the input to the booster converter and we got 5.54V and 48mA sir

    We could glow and small led but not so much Bright.

    Re: Booster converter Circuit

    Your test results appear to prove the concept. The latest plan was to supply 9V power to the IC, but bring 'tree power' into the boost stage, correct?
    Now if you truly took 1.1V @116mA tree power, then you can build a boost converter solely from tree power. Even if you illuminate one LED, that is a major achievement.

    Re: Booster converter Circuit

    Okay sir
    thank you

    What can we do sir
    to boost directly from the tree?

    - - - Updated - - -

    i searched net and i found out that they are MOSFET's whixh turn on for less voltage

    shall we try that sir?

    Re: Booster converter Circuit

    and sir one more doubt
    we are getting 48mA na sir
    then led should glow brighter but in our case it was not brighter at all

    Re: Booster converter Circuit

    A plain red led should light when you apply 1.8v. (There are other colors but they require higher voltage.) It should conduct several mA. Do not allow more than 20 mA. Install a safety resistor if necessary. If the led is exposed to too great current, it can alter its operating characteristics, causing reduced efficiency, meaning it grows dim.

    It's time to try building a boost converter which works from 1V power supply. Or else a voltage multiplier.

    Re: Booster converter Circuit

    Sure sir we will connect a resistor to it.
    thank you sir.
