    Re: AC DC full bridge power supply

    Do a 2 transistor forward converter for your 30v 5a.
    Upstream of that, do a BCM Boost pfc stage.
    ...BCM pfc stages are really easy
    ...remember to use a bridge rectifier to rectify the mains first...then go into the boost pfc.
    I think this is your smallest solution.
