Streszczenie

DC-to-DC converters are Today widely used in power conversion systems that demand a continuous source and a continuous output, and the most prominent of these systems is the photovoltaic panels system, where dc-dc converters have become an integral part of this application, thanks to the advantages offered by dc-dc converters in this application as stability The system and performance improvement, as well as raising or lowering the output voltage compared to the input voltage, and increase the efficiency of the system and achieve the maximum power point that can be produced from photovoltaic panels by application of MPPT in addition to the ability to provide a fixed output voltage in the case of a variable input voltage due to natural factors such as a change in radiation and temperature. In this study, we describe Buck, Boost, Buck-Boost, CUK, and Zeta Converters, which are the most significant non-isolated DC-DC Converters that are frequently utilized in solar energy systems. This paper also provides an overview of recent studies for each converter; we also present a comparison between these converters, highlighting the most notable benefits and drawbacks of each converter.

Abstract

Przetwornice DC-DC są obecnie szeroko stosowane w systemach konwersji energii, które wymagają ciągłego źródła i ciągłej mocy wyjściowej, a najbardziej znanym z tych systemów jest system paneli fotowoltaicznych, w którym przetwornice DC-DC stały się integralną częścią tej aplikacji , dzięki zaletom oferowanym przez przetwornice dc-dc w tej aplikacji, jak stabilność systemu i poprawa wydajności, a także podniesienie lub obniżenie napięcia wyjściowego w stosunku do napięcia wejściowego oraz zwiększenie wydajności systemu i osiągnięcie maksymalnego punktu mocy które można wytworzyć z paneli fotowoltaicznych poprzez zastosowanie MPPT oprócz możliwości zapewnienia stałego napięcia wyjściowego w przypadku zmiennego napięcia wejściowego spowodowanego czynnikami naturalnymi, takimi jak zmiana promieniowania i temperatury. W tym badaniu opisujemy przetwornice Buck, Boost, Buck-Boost, CUK i Zeta, które są najważniejszymi nieizolowanymi przetwornicami DC-DC, które są często wykorzystywane w systemach energii słonecznej. Ten artykuł zawiera również przegląd ostatnich badań dla każdego konwertera; przedstawiamy również porównanie tych konwerterów, podkreślając najważniejsze zalety i wady każdego konwertera
