In this electrical engineering experiment class, students will be introduced to a range of topics related to power electronics and motor drives, including Full Bridge inverters, DC motors, induction motors, and permanent magnet motors, along with their control.

Throughout the class, students will actively participate in hands-on experiments using the Sciamble kit. These experiments will involve connecting electrical machines and performing tasks to gain practical insights into the behavior of power electronics systems and motor drives. The primary objective of the class is to provide students with a solid foundation in electrical machines and drive systems.

By the end of the class, students will have a comprehensive understanding of the functions of power electronics controllers, the essential control techniques for motor drives, and the necessary subjects to effectively operate real-world power electronics systems.
