“…To make the conversion more cost-efficient, three-port converters (TPCs) have been proposed. In general, the topologies of TPC can be classified into two categories: isolated [1][2][3][4][5][6][7] and non-isolated [8][9][10][11]. In the low power applications where isolation is not required, a non-isolated TPC offers more benefits for higher efficiency, higher power density and lower cost.…”

In recent year, three-port converter (TPC) has been widely presented to connect the renewable source, energystored component and the load for renewable application. In this paper, a new non-isolated TPC deduced from a singleinductor-dual-output (SIDO) converter is proposed. The proposed TPC is obtained by introducing a coupling winding and a diode in the original SIDO converter. Such a derivation requires the minimal component amount and its three ports share the common ground. The derivation, operational principle and circuit analysis of the proposed TPC are presented in this paper, a prototype is also built to verify the analysis. The experimental results show the validity. Due to the compact-size, low-cost, common-ground and full-control features, the proposed TPC can be widely used in the lowpower on-board applications.978-1-4799-6735-3/15/$31.00 ©2015 IEEE

“…However the problem is, that three ports are not common-ground, which may bring in unexpected EMI problems. In [11], a new family of singleswitch non-isolated TPCs with switching frequency and duty-cycle as control variables is proposed. It uses only one switch and thus is simple.…”

“…This converter is obtained by integrating two traditional buck converters together. The detailed analysis of this converter has been reported in [17], including the derivation of the converters and the design of the parameters. By merging a two-inductor boost converter and a two-inductor buck converter together and using an additional inductor to realize the voltage-second balance of all the inductors, a three-port converter with three switches as well as three inductors is proposed in [18] as shown in Fig.…”

By combining any two of the three basic converters (buck, boost, and buck-boost converter), a family of novel twoinductor three-port DC-DC converters is proposed in [17]. These converters use only one switch to manage the power distribution among the three ports, which reduces the size and cost of the converter significantly.…”

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.

In this study, conventional dc/dc converters are integrated with a battery for renewable energy applications. The proposed battery-integrated dc/dc converters (BICs) can be compact size because these converters comprise just two switches and two diodes. Smaller size and desirable efficiency of the proposed BICs make it possible to use BICs in grid-connected (ongrid) distributed photovoltaic (PV) systems. The proposed BICs provide constant output power (less fluctuation) in different irradiance levels in distributed PV systems resulting in a constant output voltage at the connection point of BICs to the DC link. Besides extracting maximum power from the renewable source, output voltage is properly regulated on reference voltage in the proposed BICs. Depending on the utilisation states of the battery in grid-connected distributed PV systems, the operation of BICs is described in three scenarios. A linear quadratic regulator (LQR) control is applied to regulate output voltage and power of renewable source on references for three scenarios. Finally, the performance of the proposed BICs with LQR controller is verified by simulation (in PSCAD) and experimental results.
