     Hello Taketo-san,

    attached the side view of my converter; max. height is dominated by input capacitor size H13,
    height 13.5mm, and transformer Payton #55880, here height is <15mm.
    I made this design almost a decade ago, would go towards newer FETs and would replace input
    capacitor by Panasonic hybrid 2x 47uF/80V ZC series.

    Attached the stress analysis at nominal input 48V; at full load 35A the supply needs forced cooling.

    Best regards, Bernd
