Description
This module identifies the major classes of active devices deployed in power electronics systems and shows how the active device limits the performance of all power electronic systems, and how the device performance specification is controlled by the material, design and construction. The module considers ideal device models which are limited in applicability by the physics but enable simpler circuit design. An appreciation is given of the importance of the driving and protection circuits in enabling optimised circuits to perform reliably.
Topics from earlier modules (electronic circuits, phasor analysis, multi-phase systems, semiconductor devices and electrical machines) are built upon to gain an appreciation of the methods of analysis and design appropriate to converters and inverters, DC choppers and cyclo-converters and the main performance degradations in such systems (such as overlap).
The module provides an introduction to and examples of the applications of power electronics devices in systems and an introduction to the application of these components to DC motor control and other applications.
By the end of the module students should have a good understanding of:
- Semiconductor devices for power electronic applications (e.g. diodes, bipolar junction transistor Field effect transistors, thyristors, modern semiconductor materials)
- High power passive circuit components
- DC and AC voltage, current and power
- Power conversion systems and applications
- Power Supplies
- Appreciation of Smart grid techniques.
