    forward vs flyback topology

    what is better for low noise,ripple and high efficiency
    forward or flyback

    Re: forward vs flyback topology

    It depends upon the current and voltage requirements but, in general, a forward type converter would have lower noise, ripple, and (perhaps) better efficiency. The forward converter is also usually a more complicated design.

    Re: forward vs flyback topology

    whatever the input current waveform shape of a forward converter, you can make a flyback with that same shaped input wavefrom.

    so from the input its exactly the same.

    They are indeed the same.......maybe at the secondary the forward can have a bit lower peak current peak.

    But two transistor forward and two transistor flyback are both applicable where the other one is.

    Re: forward vs flyback topology

    but how to control 2 switch forward with pwm designet for single switch
    if i use a transformer or some logic, or single switch forward?
    also for high power, low noise 100v 25a what topology should i use
    and if i filter it with 2 differential filters, i should get very low noise (<800uV i hope)
