A Dynamic Electrical Scheme for the optimal reconfiguration of PV modules under non-homogeneous solar irradiation

2012

This paper presents a strategy for the maximization of the output power of photovoltaic (PV) systems under non homogeneous solar irradiation by means of automatic reconfiguration of the PV arrays layout. The innovation of the proposed approach is the employment of a simple Dynamic Electrical Scheme (DES), allowing a large number of possible modules interconnection, to be installed between the PV generator and the inverter. The models of the PV generator and of the DES have been realized and simulated with Simulink (Dynamic System Simulation for MATLAB). The attained experimental results appear to be quite interesting in terms of the attainable benefit in power and thus energy terms. The lim…

DC-DC Converter for Photovoltaic Application with MPPT function embedded interleaved 4

2012

We present a DC-DC converter for photovoltaic (PV) applications that is suitable for a distributed power conversion approach, obtained by transferring part of the electronics from the inverter to the module. The proposed circuit is a high-efficiency four-phase interleaved boost converter employing relatively low-valued inductive and capacitive components. Its realization is made possible thanks to the design of a dedicated integrated circuit (IC) performing the converter control section as well as the Maximum Power Point Tracking (MPPT) algorithm. The solution is designed for a maximum delivered power of 300 W and to work with MPPT voltage between 9 V and 40 V, with maximum allowed panel cu…
