“…За певних удосконалень [14] QZ може працювати і в двонаправленому режимі, тобто передавати потужність зі входу до виходу, і навпаки. Подібно до QRC, QZ також реалізовує варіант «м'якої» комутації ключа, зменшуючи втрати на перемикання, що своєю чергою підвищує ККД, та дозволяє отримати менші пульсації струму [15].…”

Currently, there is a problem of ensuring a stable electricity supply in Ukraine, caused by the terrorist activities of an insidious neighboring country. Stationary solar power stations consisting of an array of solar panels are one of the most important components of autonomous power networks.The main functional subsystem in autonomous electrical networks is the power part, and most of its units are connected to the internal DC power link. The task of the controller of the entire system is to keep the voltage in this link stable, which is provided by certain units, depending on the operating mode. It is also convenient to use constant voltage for cascading in order to increase power.Taking into account the variety of existing topologies and methods of tracking the point of maximum power, the purpose of this work is to review the topologies of converters, classify MPPT algorithms and compare them according to the following criteria: set of sensors, computational complexity, tracking speed, tracking accuracy, cost, amount of used memory, stability, efficiency.On the basis of the conducted analytical review, a comparative table was compiled for the considered algorithms. In the process of comparing the main MPPT algorithms, it was established that intelligent algorithms have a number of advantages over the basic (simpler) ones - higher efficiency, very high stability, high tracking speed and accuracy of finding. But the implementation of such algorithms is complex and requires more computing resources, which was a significant problem until recently

“…The literature [16][17][18][19][20] presents a good overview of the various impedance source converter topologies. However, the practical implementation of extended boost topologies is not popular due to their use of large number of components and additional power losses [21][22][23][24].…”

This paper presents a comprehensive review based on the features and drawbacks of the quasi-switched boost inverter (qSBI) topologies. The qSBI derived configurations are well suitable for low power applications due to their reduced number of components. This work focuses on the topological review of qSBI derived topologies and serves as a reference for further derivation and research on the selection of suitable topology for the specific renewable energy applications, particularly based on the photovoltaic (PV) converters.

“…New solutions are required to design an inverter with wide input voltage regulation along with high-power density and acceptable efficiency. For almost a decade, the impedance-source converters have attracted attention of the researchers [17][18][19][20][21][22]. But only a few attempts of industrial design can be found [23,24].…”

Increasing converter power density is a problem of topical interest. This paper discusses an interleaved approach of the efficiency increase in the buck-boost stage of an inverter with unfolding circuit in terms of losses in semiconductors, output voltage ripples and power density. Main trends in the power converter development are reviewed. A losses model was designed and used for the proposed solution to find an optimal number of interleaved cells. It describes static and dynamic losses in semiconductor switches for buck and boost mode. The presented calculation results demonstrate the efficiency of the interleaved approach for photovoltaic system. 1 kW power converter prototype was designed with two parallel dc-dc cells for experimental verification of obtained theoretical results. The experimental results confirm theoretical statements.
