Module summary
This module covers the topologies and circuit analysis of basic switched-mode power electronic converters, with design and applications examples. It also provides familiarity with the structures and operating characteristics of the main types of semiconductor devices that are used.Objectives
To learn the basics of three-phase circuits, connections, voltage and current analysis and real and reactive power calculations.To learn the fundamentals of electricity conversion from the form supplied by the source to the forms required by the load.
To understand power electronic conversion techniques, including the basic converters (DC-DC, AC-DC and DC-AC) and their power switching and control methods.
To learn the methods of circuit analysis applicable to switched mode circuits.
To gain familiarity with the essential properties of the relevant semiconductor devices.
To be able to design simple converters for practical applications.
