Abstract

European efficiency definition demonstrates that photovoltaic generators operate in average between 30% and 100% of its rated power 80% of its working time. Nowadays, converters are designed with a maximal efficiency working point, but often, this point does not fit with the correct power range. This paper presents a structure with a parallel connection of n converters to obtain higher conversion efficiency for the power range between 30% and 100% of the rated power. The European efficiency has been improved and higher energy production has been achieved with this new structure.
