“…Since buck‐boost DC‐DC converters generate only output voltages higher/lower than or equal the input DC voltage with negative polarity, the reference voltage of each converter has two components: namely, AC and DC components. The AC component is a sinusoidal function while the DC component is a negative DC bias which is greater than the peak of defined AC component 33 as shown in Figure 2B. The AC load is connected differentially between output of DC‐DC buck‐boost converters in this type of inverters, which results in having AC voltage across the load with zero differential DC voltage 30 …”

“…To have both boosting and bucking capabilities, three‐phase three‐legs buck‐boost inverter was previously presented, based on bidirectional DC/DC buck‐boost converters 28 . The buck‐boost inverter is naturally producing AC output voltage lower/higher than the DC input voltage via controlling the duty cycle of involved DC‐DC buck‐boost converters 29–33 .

Renewable energy sources (RESs) need power-electronics-based converters to deliver the acquired power to the grid. Those converters should provide voltage-bucking/boosting capabilities to accommodate various grid modes specially for three-phase distorted commonly unbalanced distribution utility networks. Several power electronic-based converters have been elaborated to fulfill this high-demand market. Single-stage converters are the most dominant in the market where the current source inverters (CSIs), impedance source inverters (ZSIs), and boost inverters are the high-end candidates. The aspects of cost, footprint, and minimal numbers of active switches, in addition to simplified controllability, build the main challenges that face the evolution of robust renewable energy-associated grid-tied converters. This paper presents a novel three-phase differential-mode buck-boost inverter based on two bidirectional buck-boost DC/DC converters and one differential power processor (DPP) unit. The proposed topology is a single-stage DC/AC converter offering bucking/boosting capability, with reduced hardware requirements. The proposed topology features a simplified control methodology in addition to reduced size and cost of the hardware setup which makes it more suitable for grid-tied renewable energy applications. The operation principles, small-signal model, and control strategy of the proposed topology are also illustrated. Simulation and experimental results are presented in details to verify the topologyenhanced performance under various operating conditions. The deducted results elucidate the viability of the proposed configuration alongside with the claimed merits.

Currently, renewable energies are part of the strategies adopted to promote the change towards a new, more efficient and diversified energy system. The world is moving through the change of systems electrical isolated what they use sources from generation based in hydrocarbons by hybrid generation electrification schemes that use renewable energy sources. In this article, the electrical microgrid systems without connection to the National Electroenergetic System, also known as isolated microgrids, are treated. Firstly, the target community is characterized both electrically and geographically. The case study of the technical-economic feasibility of the implementation of a microgrid in the Cuarto Congreso community, located in an isolated area belonging to the municipality of Fomento located in Sancti Spíritus, is developed. In this study, different variants of electricity supply for the community were designed by simulation using the HOMER software, taking into account the existing conditions in it. Finally, the results obtained are electrically validated.
