Analogue electronics is necessary for signal sensing, amplification and filtering before digital techniques can be applied. Power electronics is necessary where efficient manipulation of electrical energy is required, for power supply, motion control and other applications. This course covers the basic principles of both analogue and digital electronic circuits, and the constraints that real components and devices place on these circuits. Emphasis is placed on circuit analysis and design skills.
In general semiconductor devices can be used in two ways – either in their linear operating regions, or as on/off switches. Instrumentation, amplification and filtering applications tend to use devices in their linear regions as amplifiers. In applications where high power or long battery life is necessary (or in digital systems), they are used as switches. Modern electronic circuits depend heavily on semiconductor switching-based power electronics for safety, stability and control, and on analogue electronics for sensing and signal conditioning. This course aims to equip students with in depth knowledge and fundamental design and analysis skills relating to• Power or switching circuit and component design, including dc to dc, dc to ac, and ac to dc conversion circuits. • Linear electronic circuit design, including noise, instrumentation, amplification and filtering.Topics covered:Power Electronics• PWM generation• Buck, boost, buck-boost and fly-back converters• Magnetics and energy recovery• Forward converters• Sinusoidal PWM• Motion control• Single and three phase rectifiers• Brushless DC motor controlAnalogue Electronics• Noise • OP-Amp circuit design• Instrumentation amplifiers• Filter Design• A/D conversion
At the end of this course, the student will be able to:Understand and analyse common dc and ac sourced power electronic circuitsUnderstand the use of inductors and capacitors in power electronic circuitsUnderstand and implement the basics of magnetic circuit designUnderstand how real circuits and components differ from idealised circuits and componentsDesign a converter and motor control systemUnderstand sources of noise and interferenceUnderstand design methods to minimise noise and interferenceDetermine analogue filter parameters and implement them in a circuitUnderstand A/D converter operation.
