    efficiency Boost vs Flyback

    Hello friends


    efficiency Boost vs Flyback
    Regardless of isolation , Which is more efficiency ?

    Vin = 24V
    Vout = 400v
    Iout = 10A


    Thank You,

    Re: efficiency Boost vs Flyback

    Hi,

    4000W...as flyback? Are you sure?
    170A at least at the 24V side....

    Please don´t contact me via PM, because there is no time to respond to them. Thank you.

    Re: efficiency Boost vs Flyback

    This depends a lot on the boost ratio. High ratio simple
    boost converters suffer a lot efficiency-wise when you
    arelooking for high step-up; the flyback lets you take
    voltage gain by turns ratio and relieves some of that.
    But at the cost of complexity etc.

    Re: efficiency Boost vs Flyback

    transformer based ckt is by far the most practical and efficacious here...

    Re: efficiency Boost vs Flyback

    It was wrong. I mean full bridge converter

    Re: efficiency Boost vs Flyback

    You originally asked about boost vs flyback. Now
    what, bridge vs both?

    I'd bet that somewhere somebody has compiled a
    list of best-in-class efficiencies for every switcher
    topology known.

    But how useful that is, in affordable-components
    reality, is a whole 'nother question.

    I think given the simplicity of the question, finding
    a proven design with an acceptable efficiency -
    "which is best" being irrelevant if you can't handle
    the development - is where you ought to spend
    your inquiries.

    Re: efficiency Boost vs Flyback

    it sounds like you need several full bridges in parallel because of the high current
