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 include: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• Active Filter Design
At the conclusion of this course you should be able to:LO1 Understand, analyse, and evaluate the performance of DC and AC sourced power electronic circuits, including consideration of safe operation (WA1, WA3, WA7)LO2 Identify the differences, similarities, and limitations of idealised and real components in the application of power and analogue electronic circuits (WA3, WA4, WA5)LO3 Analyse and design power and analogue electronic circuits, accounting for magnetics, and sources of noise and interference, using modern techniques and tools (WA1, WA2, WA3, WA4, WA5)LO4 Communicate the design of power and analogue electronic circuits in written form (WA10)LO5 Collaborate with and provide feedback to peers (WA9)
