Anil Tekale | Radharaman Saha | Pratik Ghutke | Swapna God "Implementation of Fuzzy Based Grid-Tied PV System for Single Phase Transformer less Inverter with Charge Pump Circuit Concept" Published in International Journal of Trend in Scientific Research and Development (ijtsrd), ISSN: 2456-6470, Volume-3 | Issue-4, June 2019, pp.163-171, URL: https://www.ijtsrd.com/papers/ijtsrd23583.pdf

This paper proposes a implementation of a single phase transformer less photovoltaic inverter for grid connect PV system. We are developing new topology to eliminate the leakage current in which concept of charge pump circuit is introduced. In this paper, for controlling purpose we are utilizing Fuzzy Logic Controller. The neutral of the grid is directly connected to the negative polarity of the PV panel that creates a constant common mode voltage and zero leakage current. During the negative cycle, the charge pump circuit generates the negative output voltage of the proposed inverter. Therefore, according to the proportional resonant control strategy is used to control the injected current. There are various advantages of the proposed inverter they are the neutral of the grid is directly connected to the negative terminal of the PV panel, so the leakage current is eliminated, its compact size; low cost; the used dc voltage of the proposed inverter is the same as the full-bridge inverter (unlike neutral point clamped (NPC), active NPC, and half-bridge inverters); flexible grounding configuration; capability of reactive power flow; and high efficiency. By using simulation result we can verify the concept of the proposed inverter and its practical application in grid-tied PV systems.
