Teaching Methods
The learning methodology of this curricular unit is based on oriented tutorials and seminars. The student has to develop a research on the topics of this course and then discuss with the students all the acquired knowledge.
Learning Outcomes
This course intends to analyze several high-power converter topologies, drive system configurations and advanced control schemes. The course provides an overview of high-power MV drives, which includes drive system configurations, typical industrial applications, power converter topologies and semiconductor devices.
Special attention will be given to multilevel converter topologies for voltage source and current source converters, based on neutral point clamped and cascaded H-bridge converters. Modulation schemes for the multilevel converters such as trapezoidal pulse width modulations, selective harmonics elimination and space vector modulations are presented.
Two control schemes, field oriented control and direct torque control, are analyzed.
Some projects developed in the Matlab/Simulink© platform are explored.
