The best way to avoid MPPT drawbacks due to mismatching phenomena is to use a dedicated DC/DC converter, in charge of MPPT, for each PV panel instead of a big central converter for the whole PV array. Dedicated DC/DC converters can be boost-like converters; they must be serially connected each other to obtain an higher voltage as required by the grid inverter. However, when the number of PV panels...
On the base of the MMC principle, this work considers different topologies of sub module (or elementary converter) which make the High Voltage AC/DC converter more flexible and easy suitable respect to different voltage and current levels. A topological study is consolidated and extended on three different topologies proposed as elementary converter and their employment for the MMC structure is treated...
An innovative conversion system called synchronous active front-end (SAFE) is considered one of the most efficient solutions that successfully manages the well known trade-off between high power handling and good power quality. In wind energy applications switching converters are used to transfer the captured power to the grid. Their non-linear behavior must be considered, since the injected power...
