PROJECT TITLE :

Study and Implementation of a High Gain Bidirectional DC-DC Converter for Photovoltaic On Grid Systems - 2017

ABSTRACT:

The aim of this paper is to present a bidirectional dc-dc converter with high-stepping ratio for photovoltaic systems operating in parallel arrangement operating with energy storage systems. The converter utilizes a resonant LC circuit to continue provide an increasing voltage at the output terminals by rotating the polarity of the capacitor using a thyristor primarily based H-bridge. Compared with the existing converters, the proposed circuit reach higher voltage gains with low switching frequency using simple circuitry. It works efficiently with minimal switching loss even coping with high currents. The prototype has shown the usefulness of the converter for low input voltage applications, mainly when a string of photovoltaic panels is connected in parallel, with the chance to feed during a industrial inverter and battery banks comprising a dc bus bar.
