Abstract
A first aspect of the invention relates to an isolated DC-DC power converter which comprises at least one transformer which comprises a primary side winding and a secondary side winding wound on a common magnetic core. The isolated DC-DC power converter comprising a plurality of stages, each stage comprising a controllable switch and a winding inductor. The winding inductors of each two adjacent stages are connected via a controllable coupling switch so as to serially connect or disconnect these winding inductors to form the primary side winding with an adjustable number of turns. The isolated DC-DC power converter comprises a shared active clamp circuit for the controllable switches.
