Abstract

Novel individual power extraction topologies through partial current processing (PCP) technique are proposed for series connected photovoltaic panels. In the presented PCP technique only the mismatch currents between the series connected panels are processed. Both of the proposed current fed and voltages fed topologies process the mismatch currents without the need for an isolation transformer. These features increase the system efficiency while decreasing the ratings of the power electronics interface. The simulation and experimental results are presented in this paper to confirm the validity of the proposed configurations, and to verify its effectiveness.
