Abstract
This paper proposes a new multi-port converter with interleaved magnetic coupling technologies for integrating complex dc power systems. With the focus on the impedance behavior of coupled magnetic components and the operate parameters, this multi-port converter integrate one isolated dc-dc converter and two multi-phase boost converters and controls these topologies independently. From this integration, the proposed converter is able to connect four dc applications or sources in one circuit, which signifacantly reduces the cost and reduce the total power consumption of systems such as electric vehicles or grid-connected industries. In this paper, the basic circuit behavior is clarified, and the theoretical considerations are verified by experiments. An application example of the proposed circuit as a multifunctional system is demonstrated with simulation results. Such an approach may open up various application fields for the future dc electric power system.
