Abstract


Abstract: Owing to low cost and system compactness, transformerless inverters became popular in single-phase grid connected photovoltaic (PV) systems. Improvement of conversion efficiency, reduction in distortion of the grid current and minimizing common mode leakage current are the major concerns in these inverters. The purpose of this paper is to review on various transformerless solar PV inverters. In this paper, the single-phase inverters are classified into two major categories: 1) Nonpatent Survey and 2) Patent Survey. These two categories are further divided in various subcategories. Each subcategories are elaborated and their merits and demerits are discussed. This paper provides in depth analysis of several single phase solar PV inverters. Thus, it can be taken as reference for researchers.
