INTRA-MODULE DC-DC CONVERTER: TOPOLOGY SELECTION AND ANALYSIS

ABSTRACT: In this paper, firstly the effect of partial shading on output power of a photovoltaic system is discussed and the limitations of a centralized power conversion for extenuation that problem is described. Here, the aim is to discuss the limitations of the state-of-art power conversion system and to analyze the possible solutions. The benefits of the distributed power conversion in terms of overall photovoltaic system efficiency are explored. This work presents the requirements of the intra-module converter in photovoltaic system and also discusses the different factors that need to consider while implementing a DC-DC converter as an intra-module converter. A topology of high gain DC-DC converter is presented here, which can be used in photovoltaic applications as an intra-module converter. This paper also demonstrates the suitability of this presented converter in photovoltaic applications. Simulation results of the proposed converter are also presented here.
