Step-Down dc-dc Converter Eliminates Ferrite Cores at 50kHz Enabling Power Supply on

[BWRX]

Interesting article from Slobodan Cuk that I hadn't seen before: Step-Down dc-dc Converter Eliminates Ferrite Cores at 50kHz Enabling Power Supply on Chip with One-Cycle Transient | Power Electronics

Looks very interesting, thanks!

Always interesting reading when written by Dr. Ćuk. For audio purposes perhaps less obvious with a considerable ripple current at the output.

Wow, he is such an Old Timer that his schematics call semiconductor diodes by the name "Crystal Rectifiers". Straight out of the mid-1950's.

He's not that old. Late 60s probably

Around 70, I guess from this description of his studies:
