"I know that , but why do the 50khz versions weigh so much and are so
bulky? Iron losses at that frequency?

Two problems there. First, I read 50 Hz when I should have read 50
kHz, so my original remark addressed the wrong topic. More to the
point, were you talking about a 50 kHz ROTATING machine? I don't think
there's anything like that around these days, but could be wrong. All
of the high-frequency power supplies that I'm aware of involve
oscillators and power amplifiers, formerly high-power tubes and now
solid state. Those could be big and heavy.
