Synopsis:

The course aims to provide students with knowledge in two main areas. The first area covers the fundamentals of electrical engineering, i.e., passive, active, and semiconductor circuit elements, electrical circuit analysis, and power in electrical circuits. This area also includes the issue of occupational safety when working on electrical equipment. The second area focuses on electric drives and other electrical technologies relevant to sustainable mobility systems: direct current (DC), induction, and synchronous motors, transformers, fundamentals of power electronics and converters, energy storage devices, and power systems.
