Design of boost-power-stage converter for PV generator interfacing

Abstract

This paper investigates the benefits which can be obtained if the maximum output current of a photovoltaic (PV) generator is taken into account in the design of a boost-power-stage converter. The investigations clearly show that the benefits are smaller inductor core size and more uniform temperature distribution among the power electronic components compared to the conventional design method. It will also be shown how to make the design with small input capacitor and how to take the power decoupling into account in the design process.
