#### Electric Drives and Traction - B1M14EPT1

##### Main course
 Credits 5 Semesters Winter Completion Assessment + Examination Language of teaching Czech Extent of teaching 2P+2L
Annotation
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.
