“…Within the residential inverters we find characteristics such as multi maximum power point tracking (MPPT) input, storage ready, EV charger integrated, built-in Revenue Grade Meter, additional power supply input, or network connectivity [22,23]. Commercial grid-tied inverters include features as seamless switchover, prioritize self-consumption of renewable sources or stored battery, support large loads to avoid grid peak usage, efficient fast charge, scalable battery reserve, embedded controls for sell surplus generation or curtail the production, integrated reactive power regulation functions, multiple MPP trackers, WLAN or Wi-Fi access for system monitoring and control functions [22,23]. • EV charging systems: Nowadays there are four modes of EV charging systems defined by the IEC [24,25].…”

At present, the energy transition is leading to the replacement of large thermal power plants by distributed renewable generation and the introduction of different assets. Consequently, a massive deployment of power electronics is expected. A particular case will be the devices destined for urban environments and smart grids. Indeed, such applications have some features that make wide bandgap (WBG) materials particularly relevant. This paper analyzes the most important features expected by future smart applications from which the characteristics that their power semiconductors must perform can be deduced. Following, not only the characteristics and theoretical limits of wide bandgap materials already available on the market (SiC and GaN) have been analyzed, but also those currently being researched as promising future alternatives (Ga2O3, AlN, etc.). Finally, wide bandgap materials are compared under the needs determined by the smart applications, determining the best suited to them. We conclude that, although SiC and GaN are currently the only WBG materials available on the semiconductor portfolio, they may be displaced by others such as Ga2O3 in the near future.

“…The presented multi-port inverters (MPIs) can be classified into single-stage configurations, which do not have DC bus, and multiple stage structures that include DC bus before inverting DC power to AC. 12 The converters in previous studies [8][9][10][11] are single stage with two input ports that do not have any battery connection due to their unidirectional input ports. In Haddadi et al, 8 a single-stage grid-tied MPI connected to two similar sources is proposed which has low certainty in providing power because of not using different kinds of sources or a battery.…”

“…A few numbers of research have been done recently in the field of multi‐port inverters 8–11 that need further development especially for non‐grid‐tied applications. The presented multi‐port inverters (MPIs) can be classified into single‐stage configurations, which do not have DC bus, and multiple stage structures that include DC bus before inverting DC power to AC 12 . The converters in previous studies 8–11 are single stage with two input ports that do not have any battery connection due to their unidirectional input ports.…”

“…It seems that the requirements of having a bidirectional port and improving quality of AC outputs can be met via using more components as in Singh et al 11 and a DC link capacitor. The authors in Elmakawi and Bayındır 12 discus some different models of MPIs with single and multiple stages presented in the last decade. The configuration in Thang et al 13 converts DC power of PV and battery to AC with low voltage gain.…”

SummaryThis paper presents a new single‐phase multi‐port DC–AC converter with high voltage gain in low duty cycle. The operation of the proposed converter consists of four modes, especially battery‐alone mode, which makes it appropriate for stand‐alone renewable applications. Using a suitable boosting method, this converter can achieve high voltage gain in all modes. The high gain performance of the converter occurs at both low shoot‐through duty cycle and high modulation index. Therefore, the output voltage and current harmonics as well as the filter size are reduced. In addition, the converter transfers the power with a continuous current through its input ports and has a common ground between the input sources and the inverter bridge. The positive features of this converter are the result of the appropriate design and localization of the bidirectional port that connects the battery to the converter. The proposed configuration includes an impedance network that protects the converter in the shoot‐through states and takes the advantage of the shoot through in its boosting performance. Another advantage of the proposed converter is that the voltage stress on the power switches on the DC side is considerably low. In order to validate the feasibility and effectiveness of the converter, a prototype rated at 110 V is prepared and tested.

Using a hybrid renewable energy source with an energy storage system, this paper proposed a novel multi-stage non-isolated three-port converter with a 5H inverter to feed a residential load varying from 50 Watts to 3500 Watts. The proposed three-port converter operates in grid-tied and standalone power modes. A novel demand-side management algorithm, which covers eight operation modes, is described. Additionally, a complete control system is discussed. The proposed control system controls the PV maximum power point and battery charging/discharging, and regulates the 400 V DC bus voltage, the load voltage in standalone mode, and the grid-tied injected current. The proposed converter and the control system are validated through simulation for all power modes. The simulation results reveal that the proposed system is viable for Building-Integrated PV Systems.
