“…Electrical power conversion usually depends on power electronic converters in shaping the electricity from one form to another using semiconductor devices (e.g., switches and diodes), passive elements, and storage devices [1]. The power electronic converters are mainly classified, based on their power range, into low-power, medium-power, and high-power converters [2]. The low-power converters are important in many applications, such as renewable energy systems (RESs), including photovoltaic (PV) systems, fuel cells, battery energy storage (BES) systems, chargers, and power supplies [3].…”

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.

“…The unity power factor operation is achieved with a compact and efficient fifteen-level PUC converter-based grid-tied system. In addition to these, in (Alotaibi et al, 2023) the scientist presents a new three-phase modular inverter which is based on a novel dual-isolated SEPIC/CUK converter for large-scale PV power plants. The proposed three-phase modular inverter is produced from series DISC submodules to reduce the size and improve the performance of the energy conversion system.…”

Multilevel converter to access maximum power from distributed energy source based smart grids

et al. 2023

The distributed power generation is increasing rapidly, and its integration into the power system is a critical issue for the existing power network. Therefore, a three-level converter is developed to access and control the medium voltage DC generated from a photovoltaic system in a smart grid. A conventional three-level neutral point clamped circuit is incorporated into the conventional inverter. The conventional inverter is a pulse width modulation-based inverter that achieves zero switching currents and supplies power to the load. This technique suppresses the switching power loss up to a large extent. Additionally, switches conduct half of the input voltage; therefore, the output voltage is significantly similar to the voltage of the output filter. Moreover, in the proposed converter, the stress of voltage on diodes is minimal, which increases the input range of voltage in smart grids. The overall efficiency of converter is around 97.9% and voltage gain is around 42. In addition to these, a detailed design description and analysis are carried out in this paper. In the end, a prototype is developed for experimental analysis to validate the operating principle and characteristics of the proposed converter.
