“…Series connected energy sources are proposed in [5], however the system will fail if one of the stage is diminished. In [6], a phase-shift PWM control scheme is proposed to transfer power to load simultaneously by using a multi-winding transformer, but it increases the cost and size because of more switches and controllers.…”

“…Although some MIC topologies were reviewed in [6] and [10], these studies were only focused on the combining methodology of an MIC topology for connecting its input sources. Specifically, the combining strategies used in [6] and [10] can be classified by the following three methods: sharing an output filter capacitor [14], sharing some power electronics switches, energy transfer inductor and capacitor [10,15], and sharing a magnetic core [8,9,11,13].

-A power system designer may have difficulties in choosing a suitable multiple-input converter topology for a specific target application because each multiple-input converter topology presented in the literature has its own advantages and disadvantages. In this perspective, this paper presents a systematic topology selection method for multiple-input converters with three comparison criteria including cost-saving effect, modularity potential and flexibility. Based on these criteria, this paper proposes a strategic flow chart example for choosing a proper multiple-input converter topology. This flow chart will provide a powerful selection tool to a power system designer when he or she chooses a specific multiple-input converter for a given application.

“…Thus, parallel-connected topologies have been traditionally popular. For example, the time-sharing technique [19] and the multi-winding transformer flux additivity method [20] effectively utilize magnetic coupling to parallel-connect DERs. Although they result in a reduction in the number of the NPC inverters Fig.…”

Abstract-This paper presents a new family of bidirectional multiport power sharing converters for high-power clean and renewable energy technologies with utility-scale energy storage and medium voltage grid interface. The proposed topology allows for multiple dc-voltage distributed energy resources to be individually referenced to ground and connected via highfrequency isolation to a single multilevel inverter with utility interface. Multiple system level architectures are presented, each implementing power sharing converter technology, and offering adjustable four-quadrant power flow for the system. A case study examines a 1-MW four-input system comprised of a solar array, Li-Ion battery bank flow battery, and fuel cell. Simulation confirms that the fuel cell and solar sources can charge or discharge the flow and Lithium battery banks at individual rates, while supplying a steady output voltage to a medium voltage grid interface. A reduced-scale hardware prototype verifies a broad operation range for the system's power sharing ratio. Altogether, the proposed topology combines the benefits of MPC technologypower conditioning simplification and improved source utilization-as well as a unique bidirectional power sharing control for each individual port.
