ES4D4-15 Power Electronic Converters & Devices
Practically all electronic equipment, whether domestic or industrial, requires power conditioning to deliver the energy for it to operate correctly. This is using electronics for power processing, not information processing. The applications vary widely from power supplies for laptops and mobile phone chargers, through industrial motor drives, hybrid and electric vehicle drives, electric rail transport, to solar and wind energy systems and power transmission and distribution systems.
Module aims
The module aims are:
- To introduce the concept of power electronics as power processing and control, and to present the range of applications of power electronics in today’s society.
- To introduce power semiconductor devices as basic switching elements used in power electronic converters, and describe the theory of their operation.
- To introduce power electronic converters, explain their operation principles and give examples of applications.
- To develop an understanding of the issues present in converter and device design, including the impact of physical layout and heat dissipation.
- To understand the basics of DC motor drives and control
