In this paper galvanically isolated dc-dc interfaces are studied. Capacitive coupling is studied as an alternative solution to magnetic isolation. The proposed converter provides benefits including decreased size, weight, and losses, consequently improving both high power density and high efficiency compared to the inductive coupling converters. An experimental prototype of the suggested converter operated in 1.5 MHz switching frequency and rated power equal to 6 kW is presented in this digest.
