Abstract |
Photovoltaic systems must maximize their efficiency. The multilevel conversion can be an appropriate
solution to reduce the system losses. After analyzing the losses mechanisms in multilevel converters,
the main goal of this paper is to study its feasibility for photovoltaic applications. An experimental site
has been built at the LAAS-CNRS to examine different system architectures. All the architectures
include a battery set, a multilevel inverter, four solar panels, four boost converters with their respective
MPPT controllers to charge the battery set, and a data acquisition system specially designed for the
experimental site. Among the possible architectures, two of them are presented, and their respective
performances compared. |
