“…Our prior work [1] addresses the following objectives for a Three-Port Converter (TPC): high efficiency, zero-ripple terminal currents, low component count, utilizing the voltage proportionality feature of theĆuk converter to achieve reduction in weight, and performance improvement in terms of zero-ripple on all the terminals. This is done by integrating the inductor and transformers onto a single magnetic core.…”

In this paper, the three-portĆuk converter interfaces one unidirectional input power port (envisioned to be a DC power source such as PV, or fuel cell) and two bidirectional output ports, representing the grid-tied inverter dc bus and a storage port respectively, and combines all the magnetics into a single core. The well-known property of the basicĆuk converter that emulates an ideal dc-dc transformer (zero ripple terminal currents) is extended to three ports and is analyzed in detail. Two methods, one involving the physical structure of the core, and the other, a circuit-based dual approach, which is directly related to the core structure, are applied to solve the zero-ripple problem, and the accuracy of one of them over the other is verified with simulation results. Three different power transfer modes in this three-port converter are compared using the two methods mentioned above.

The application of renewable energy such as solar photovoltaic (PV), wind and fuel cells is becoming increasingly popular because of the environmental awareness and advances in technology coupled with decreasing manufacturing cost. Power electronic converters are usually used to convert the power from the renewable sources to match the load demand and grid requirement to improve the dynamic and steady-state characteristics of these green generation systems, to provide the maximum power point tracking (MPPT) control, and to integrate the energy storage system to solve the challenge of the intermittent nature of the renewable energy and the unpredictability of the load demand. In order to improve the efficiency and the power density of the overall circuit, the use of a three-port DC-DC converter, which includes a DC input port for the renewable source, a bidirectional DC input port for the energy storage system, and a DC output port for supplying the load, is a preferable solution to the traditional method using two DC-DC converters: one for the renewable sources and another for the energy storage system. In recent years, many DC-DC three-port converters have been proposed and reported in the literature. Each of these converters has its own topology and operating principle, which results in different complexities, different numbers of components, different reliability and efficiency. In this paper, a comparison of the features of different topologies of three-port DC-DC converters that have been proposed by different research groups is reviewed briefly. This review can be used as a guide for the appropriate selection of the suitable topology to meet the particular requirement of a system. The paper also discusses the potential research extension of the topologies from three-port DC-DC converters to three-port DC-AC inverters and how the voltage gain of the non-isolated three-port DC-DC converter can be improved.
