In order to register for the course B1M14EPT1, the student must have registered for the required number of courses in the group BEZBM no later than in the same semester.

Garant předmětu:

Jiří Lettl

Lecturer:

Jan Bauer, Jiří Lettl

Tutor:

Jan Bauer, Filip Baum, Ondřej Lipčák

Supervisor:

Department of Electric Drives and Traction

Synopsis:

The first part of the course focuses on the basics of designing AC drives with AC motors at different power supply types and loads, their reliability, design for potentially explosive atmospheres and for special purposes as well as the necessary technical documentation. In the second part, students are introduced to mathematical modeling, control strategies (vector control, direct torque control) and basic techniques of induction motor parameter estimation. Furthermore, the control and nonlinear behavior of a two-level voltage-source inverter equipped with IGBT elements as the most commonly used power converter for induction motors is analyzed.
