Multilevel buckboost bidirectional converter for hibryd systems with photovoltaic energy

In recent years the investment in renewable energy has been very significant, either personally or at enterprise level, and photovoltaics has suffered a strong growth. Knowing this, we tried to develop a multilevel, buck-boost, bidirectional converter for photovoltaic systems with energy storage in a bank of batteries. The converter is based on three different voltage levels followed by an inverter/rectifier block to allow the connection to the electrical low-voltage grid. In addition to the development of the topology, all the design and implementation of its control mechanisms have been completed. Afterwards we proceeded to the implementation of a supervisor that aims to control energy flow, using fuzzy logic because of its high versatility of implementation.
