Introductory description

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.

Assignment 40%

This is to design a DC-DC boost converter with a guide of the design specifications. The designed converter will be analysed via simulation using a PSPICE software and the analysis includes choosing the suitable device and components and examining the converter performance. The converter will be tested via practical laboratory experimental work. In the laboratory test, a closed-loop control will be introduced and tested to understand how the converter output voltage is maintained via feedback control.
