Clayton First semester 2008 (Day)
Sunway First semester 2008 (Day)
Switched energy conversion processes. Buck and boost converters. Modulation and control of converters. Second order issues: physical construction, passive components, magnetics, control circuits, simulation. Switched mode power supplies, isolated topologies derived from buck and boost converters. Practical applications including computer power supplies, battery chargers, UPS. Structure and operation of DC, AC and reluctance motors. Motor operation at variable speeds. Open and closed loop motor drive systems, servo motor drives, stepping motor drives, speed and torque controlled drives.
Students are expected to acquire knowledge of switched power electronic conversion circuits and their application to switched mode power supplies and variable speed electrical motor drive systems. They should be able to design, analyse, physically construct and experimentally verify the performance of non-isolated and isolated power electronic conversion systems. They should understand the operating principles of electrical motors, particularly when controlled by a power electronic converter system. They should be able to specify requirements for variable speed motor drive systems in different applications, and experimentally investigate and confirm their performance in a laboratory setting.
