Vision

The activity of GREP is framed on the Power Electronics technologies and the exploitation of the industrial applications of advanced power electronic converters.

The historical evolution of Power Electronics technologies demonstrates how new industrial applications of this enabling technology have grown unabated, mainly because of three reasons:

1. The development of new Power Electronics devices with new or improved characteristics.
2. The cost reduction of Power Electronics devices.
3. The development of new Power Electronics converters, new modulation techniques, or new control techniques improving performance features.

Our activity is focused on known advanced multilevel converter topologies and multilevel topologies developed by the research group in the precedent years. These advanced converters are based on last-generation electronic semiconductors: silicon-based classic devices (MOSFET, IGBT, IGCT), and emerging silicon-carbide devices.

GREP explores converter modulation strategies that provide improved performance, such as increased energy efficiency, reduction of voltage and current harmonic distortion, dc-link capacitor voltage balance, enhanced reliability, etc.

Finally, GREP is also developing new converter control strategies to enable the effective introduction of new industrial products.

GREP experience allows addressing current industrial challenges, such as improving existing products and creating new products in the areas of renewable energy systems and electric and hybrid-electric vehicles.

The research at GREP aims to produce a substantial socioeconomic impact through contributions to the development of the future Power Electronics technology.
