Course Overview

Power electronics in general is used to process and control the flow of electric energy by supplying voltages/currents that are optimally suited for loads. The introduction to power electronics improves your understanding of power electronic systems and applications, semiconductor devices, electromagnetic conversion, rectifiers, and switch mode direct current converters.

The introduction to power electronics training course starts with an overview of power electronics systems and continues with semiconductor devices such as diodes, thyristors, and transistors. Furthermore, an overview of magnetic circuits and electromagnetic conversion is included. Next, you will learn the operation of basic rectifiers, single-phase diode bridges, three-phase full-bridge rectifiers, and concept of inrush current and over-voltages in rectifiers.

Finally, the course covers the operation and analysis of DC-DC switch mode converters including step up converter (boost), step down converter (buck), step up-down converter (buck-boost), and full-bridge DC-DC converters.
