My first reaction would be to agree with you, but researching PSUs for
a quote the Vicor 4kW Megapak was in the frame - that uses passive
inductive correction on a rectifier/capacitor input system and claims
0.92 PF in the spec. OK, that's a bit lower than the 0.95+ that active
circuits manage, but there's a trade off against complexity and
reliability.
