Om studiet

This course will give you insight into elemental concepts, design and implementation of power electronic devices for electrical machines and off-grid and grid connected renewable energy systems. Power electronic circuits are an essential component in the control of electrical machines, and for integration of renewable and distributed energy sources; including wind turbines, photovoltaic, marine energy systems and energy storage systems.
