ECE4055 · Power electronic converters

Overview

The unit presents a structured treatment of the design of switched-mode power electronic converters. The unit starts with passive diode rectifiers followed by thyristor rectifiers. Introducing various semi-conductor active switches, commutation cells and pulse width modulation techniques, various active power electronics converters including DC/DC buck and boost converters, flyback converters, resonant converters, two-level DC/AC converters, and three-level DC/AC converters will be studied in detail. Finally, a few real-world applications such as variable speed drives and power filters are presented as examples.

Assessment

The Handbook lists an examination for this unit.

Continuous assessment: 50% Final assessment: 50% This unit contains threshold hurdle requirements that you must achieve to be able to pass the unit. You are required to achieve at least 45% in the total continuous assessment component and at least 45% in the final assessment component. The consequence of not achieving a hurdle requirement is a fail grade (NH) and a maximum mark of 45 for the unit.

Assessment details may change. Please refer to the assessment information in Moodle closer to the start of the teaching period.

Workload

The minimum total expected workload to achieve the learning outcomes for this unit is 144 hours per semester typically comprising a mixture of 3-6 hours of scheduled learning activities and 6-9 hours independent study per week. Scheduled activities may include a combination of teacher-directed learning, peer-directed learning and online engagement. Independent study may include associated readings, assessment and preparation for scheduled activities.
