Impedance Matching of Photovoltaic System Using DC-DC Converter

Selection of proper converter topology for photovoltaic-based application is one of the major design challenges faced by power electronics design professional. Impedance matching is one of the necessary and sufficient conditions which transfer power from photovoltaic source to load. Impedance matching achieved by the right DC-DC converter topology improves the utilization efficiency of the photovoltaic system. This paper studies the principle of impedance matching in photovoltaic system using different classical DC-DC converter topologies and finds the right converter topology which transfers maximum power from photovoltaic source to load.
