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 summary

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

1 - Experimental/simulation sessions attendance

2 - Report on PWM signal generation and DC-DC buck converters

3 - Report on DC/AC converter

4 - Report on solar farms simulation

5 - Mid-semester test

6 - Final assessment
