Abstract :
This paper describes a highly efficient, high power density converter generating 3.3VDC from a 390VDC input, for use in a proposed power distribution architecture with a reduced number of conversion stages, which increases system efficiency. Key design considerations, theoretical and experimental results are presented for the LLC resonant converter.
