Abstract

A power converter formed by a multitude of power cells, wherein each of the power cells is implemented on a four-legged magnetic core placed on a multilayer PCB. Each cell contains rectifier means and resonant capacitors. The cells can be interleaved with the proper delay for reduction of a ripple current through output capacitors. The power cells can be interleaved for the purpose of splitting a high input voltage bus to reduce the voltage stress on the switching elements of the cells.
