“…Buck-boost inverters play a crucial role in connecting RESs to the utility grid and ac loads when the input voltage fluctuates below and above the output voltage. The DM buck-boost inverters have been presented in several publications [22][23][24][25][26][27]. There are eleven SSSD buck-boost converter topologies; seven of them are voltage-sourced boost-type converters, while the rest are current sourced.…”

Switched-mode power supplies (SMPSs) are single-switch, two-state, dc/dc power electronic converters and can be generally classified into buck, boost, and buck–boost converters according to voltage transfer functions. There are more than 33 SMPSs with different characteristics in terms of their current and voltage ripples, voltage and current stresses, and their being voltage/current sourced. Although they are usually employed in the dc/dc mode, these SMPSs can be connected differentially to operate as single- and three-phase dc/ac inverters; hence, they are used in low-power applications. The resultant inverters will behave differently according to the topologies that they are descendant from. Several publications have presented differential-mode single-phase inverters (DMSIs) for low-power applications, focusing on their suitability for renewable energy systems. These proposals have mainly focused on boost and buck–boost configurations, with less focus on the buck inverter topologies. Also, several possible configurations for other DMSIs have not yet been proposed or discussed. This paper proposes a comprehensive review of the different possible configurations of the DMSIs, illustrating a systematic method by which to generate and explore them. The paper will mainly categorize the DMSIs in terms of their voltage transfer function and will then discuss the topologies, presenting the main advantages and disadvantages of each one.

Single-stage buck–boost inverters have attracted the attention of many researchers, due to their ability to increase/decrease the output voltage in one power conversion stage. One of the most important uses of these inverters is in photovoltaic applications, where the voltage of the solar panels varies in a wide range. In recent years, many new inverters have been proposed to improve the performance of existing structures. In this paper, the state of the art of these single-stage buck–boost inverters is discussed. The advantages and disadvantages of each structure are examined from different perspectives, such as the number of components, losses, and performance. Finally, in a general comparison, the properties of all structures are discussed and summarized in a table.

“…The developed solar cells were finally considered efficient in 1954 [15]. Photovoltaic cell applications in the form of photovoltaic panels (PVPs) became widely available, common, and efficient [16]. They found applications for compact, autonomous, and sustainable IoT devices [17], such as solar-powered BLE beacons [18], sensors [19], and also devices supplying energy in various ways: indoor light energy [20], hybrid radio and light energy [21,22], or hybrid thermal and light energy [23].…”

This paper presents the design and performance of an energy subsystem (ES) dedicated to hybrid energy harvesters (HEHs): wave energy converters (WECs) combined with photovoltaic panels (PVPs). The considered ES is intended for compact HEHs powering autonomous end-node devices in distributed IoT networks. The designed ES was tested experimentally and evaluated in relation to the mobile and wireless distributed communication use case. The numerical evaluation was based on the balance of the harvested energy versus the energy consumed in the considered use case. The evaluation results proved that the ES ensured energy surplus over the considered IoT node consumption. It confirmed the proposed solution as convenient to the compact HEHs applied for sustainable IoT devices to power them with renewable energy harvested from light and sea waves. It was found that the proposed ES can provide the energy autonomy of the IoT end node and increase its reliability through a hybrid energy-harvesting approach.
