Description
Power Electronics has evolved from static converter technology into a significant field within electrical engineering and electronics. By using power semiconductors power electronics performs such functions as switching, controlling and converting of electrical energy with the greatest possible efficiency. One area of application for power electronics is drive technology. Here, speed variable DC and three-phase four-quadrant drives can easily be realized using modern power electronics. As a result of this development we can no longer imagine industry, workshop tools, commercial enterprises and household appliances without thyristor speed control units, smooth-starting circuits, frequency converters etc. The EDULAB DIDACTIC training panel system EM-21800Q for power electronics and drive now makes it possible to convey the technical knowledge of this field.
The experiments permit practice-oriented, hands-on training to be carried out, thus assuring the trainees of the proficiency needed to handle the tasks and the equipment found in this field. The training panels and functional units with block circuit diagrams and signal diagrams permit clear and understandable assembly of the experiment circuits. Beginning with the basic circuits, the student proceeds to tackle more complex circuits in power electronics and drive technology using a proven step-by-step method designed for didactic results. And of course, the model behind the entire system is the circuitry used in industrial applications.
