PROJECT TITLE :

Operation of a High Gain Bidirectional DC-DC Converter for Photovoltaic On-grid Systems - 2017

ABSTRACT:

The aim of this paper is to present a dc-dc converter with high-stepping ratio for photovoltaic (PV) systems operating in parallel arrangement. The converter utilizes a resonant LC circuit to continue offer an increasing voltage at the output terminals by rotating the polarity of the capacitor using a thyristor based H-bridge. Compared with the prevailing converters, the proposed circuit reach higher voltage gains with low switching frequency using straightforward circuitry. It works efficiently with minimal switching loss even handling 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 likelihood to power in a business inverter.
