Abstract :
This paper presents an improved multi-channel high frequency platform operating at 700 kHz, suitable for server power supplies. It is focused on a new primary regulation loop and very high frequency magnetics for improved efficiency and EMI. In particular the benefits of multiple gapped toroids and the new single layer uniform toroidal transformer are addressed.
