DC/ AC Conversion

Electric energy is tapped at the car battery in the form of DC voltage and is then applied as a DC current. However, in modern electrical drives an AC voltage is needed with an approximate sinusoidal alternating current. In this course the generation of AC voltage and currents is described and demonstrated in a simple and graphic fashion. The knowledge acquired in the theoretical section is then verified empirically by means of experiment. All of the components needed for the experiment are arranged on a single printed circuit board. In knowledge tests the student's progress is checked and thus the most important aspects of DC/AC conversion are effectively learned in the fastest possible time.
