Single-inductor multiple-source mixer for DC power packet dispatching system

Abstract

© 2017 IEEE. DC power packet dispatching system is reported recently aiming to deliver power in a packet form. It can utilize less power conversion stages which increases power distribution efficiency and monitor load demand intelligently from source side to keep the system stable. A multiple-energy-source mixer based on a multiple-input single-inductor buck converter for DC power packet dispatching system is proposed. It is capable of generating power packets at different voltage levels by time sharing of multiple power sources. In this work, three different sources including a PV panel and two DC voltage sources are used for the power packet dispatching system. A control strategy is devised in order that the PV panel can track maximum power point (MPP) approximately and the PV is given a priority to share power in each power packet generation. Experimental results are reported to verify the proposed mixer and its control strategy for DC power packet dispatching system.
