This paper proposes a method to merge PV cells or PV panels within the internal components DC-DC converters. The purpose of this merged structure is to reconfigure the PV modules between series and parallel connections using high switching frequencies. This leads to multi-levels of voltages and currents that become applied to the output filter of the converter. As an example, reconfigurable PV-buck converter topology is presented. Its analysis, simulation and experimental verification are presen...

This paper proposes an adaptive reconfiguration scheme to reduce the effect of shadows on solar panels. A switching matrix connects a solar adaptive bank to a fixed part of a solar photovoltaic (PV) array, according to a model-based control algorithm that increases the power output of the solar PV array. Control algorithms are implemented in real time. An experimental reconfiguration PV system with a resistive load is presented and is shown to verify the proposed reconfigurations.
This paper proposes a modeling and computing algorithm to simulate and analyze the effect of non-uniform changing shadows (a passing cloud) on the output power of solar PV arrays. Each solar array is composed of a matrix of individual solar cells or solar modules interconnected in series and parallel. Bypass switches and diodes are also modeled. The model is able to determine the power loss in each solar cell and the hot spots of a shaded solar PV array as well as the PV output power. The model ...
