“…Furthermore, usage of the segmented switches allows for maintaining all the power phases active during low load condition. In [179], a combined solution of photovoltaic isolated dc/dc three-port converter is proposed to decrease the cost and enhance the power density of the sys-tem. The control approaches for the single module to get the maximum power, charge control of the battery, and main bus regulation have been proposed.…”

The power demand with interest in green power has focused researcher to develop the distributed power generation using wind energy, solar energy, etc. With the fast depleting fossil fuel reserves, energy security and environmental concerns there is a huge requirement of alternate sources of energy to fulfill the present energy demand. Distribution generating system can support the weak grids, maintaining grid power, managing balance power and enhancing the power quality. Any research work base depends on the literature survey and the studies carried out by several kinds of research and their support to research field encourages for more scope of research. The important advantages related to microgrids have led to huge efforts to grow their dispersion in the power systems. While microgrid is fast growing but there are still various challenges to efficiently control, design, and operate microgrids when linked to the main grid, and also when in islanded mode, where wide research actions are ongoing to handle these issues. This paper presents a review of issues concerning integration of renewable energy sources to microgrids and offers a description of research in areas related to economic feasibility of microgrids system, including dynamic analysis of microgrid hybrid system in grid-connected mode, application of power electronics, microgrid operation, and control.

“…28 The converter proposed in [45]. Different from the above presented converters, which integrate the input port and the bidirectional port to the primary side of the high-frequency transformer, a novel partly-isolated converter, which integrates the bidirectional port and the load to the secondary side of the transformer and the PV is isolated at the primary side of the transformer, is proposed in [46] as shown in Fig. 29.…”

“…29. The detailed derivation of the proposed converter from the traditional half-bridge converter is introduced in [46]. The output circuit of the traditional half-bridge converter is detached first and then a boost converter is inserted between the two detached outputs to provide the power flow path between the battery and the load; finally a boost converter is applied in the input port to minimize the ripples of the input current.…”

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.

“…To eliminate this problem a two winding transformer is used [16][17][18][19][20][21][22][23][24]. By losing the isolation between the energy sources of single side of the isolation transformer the total number of switches in this type of topologies are reduced and Battery is connected at secondary side of the isolation transformer, the battery does not require any isolation to the output of the load [25][26][27][28][29][30][31][32].…”

This paper Presents comparative analysis of IBSPFC &QSC Based IBSPFC by using FPGA. By using this IBSPFC the voltage stress is reduced across the switch when compare to conventional fly-back converters. The multi winding transformer gives higher reliability i.e. if any one of the winding damages other one supplies power to the load. On the other hand, QSC based IBSPFC will achieved Zero voltage & Zero current switching, which will increase more efficiency when compare to conventional single stage integrated converters and IBSPFC. Operating modes of QSC, based IBSPFC&IBSPFC have been introduced. The primary side winding of the fly-back transformer is coupled in series across with bulk capacitor to minimize switch voltage stress and the secondary winding of the 1:1 fly-back transformer. Basic voltage mode control Techniques are used to control the output voltage and current. An input voltage of 25V primary side and 50V battery at secondary side, 100v output, 100W and 100KHz DC-Dc isolated QSC based IBSPFC is implemented using FPGA SPARTAN6LX9 and experimental results and comparative table have been presented.
