### Pre-Requisite Knowledge

Circuit Theory and Analysis

### Summary of Content

This module examines power electronic devices, circuits, systems and application. An understanding of the operation and characteristics of the system components will be developed. This will be followed by a study of the performance of a range of power electronic converters and their application. Circuit design and analysis techniques will be developed and ECAD will be employed as appropriate

### Syllabus

The teaching syllabus will cover the following areas: Power Electronic Devices : Construction and characteristics of different power electronic devices like Diode, Thyristor, power BJT, power MOSFET, TRIAC, IGBT and GTO. Cooling and Protection: Thermal model, peak and average temperature, transient thermal impedance, cooling system specification . Rectifiers : ac/dc 1-phase and 3-phase controlled ( full and half ) and uncontrolled converters, mean voltage, waveforms, power factor, distortion factor, overlap; Inverters : single phase dc/ac inverter, Voltage Source Inverter, PWM, Quasi -square. Noise and Thermal Aspects: Harmonic sources, analysis techniques (e.g. Fourier), EMC considerations (coupling mechanisms, screening, interfaces, grounding, filters, measurement standards, circuit layout); Choppers : dc/dc converters, forward, flyback, resonant and Cuk, voltage regulation and ripple, filter specification; Cycloconverters : Basic AC/AC 1-phase cycloconverter. Applications : Electric motor drives, switch-mode power supply, HV DC link, static var compensator, UPS, lighting and heating controls. Power systems(FACTS) ECAD : Structure, modelling strategy, device/circuit/system and behavioural modelling, parameter determination, schematic input, steady-state and transient analysis, post-processing (voltage, current, power, harmonic analysis).

### Learning Outcomes

On completion of this module the student should be able to:1. Describe the characteristics of a range of power electronic devices and relate these to typical applications.(AM1)2. Analyse the thermal aspects of power electronic devices and outline appropriate protection schemes for these devices(AM3)3. Describe and analyse AC/DC, DC/DC, AC/AC and DC/AC static power conversion schemes (AM7)4. Describe applications of power electronic conversion schemes and develop a product specification for such schemes synthesised from the needs of the application.(AM1,AM4)5. Describe the principles of Electromagnetic compatibility (EMC) and harmonic filters.(AM1, AM6)6. Work in a project team to solve a power electronic application problem. (AM8, AM9).

### Teaching / Learning Strategy

The main teaching method will be based on lectures with laboratory exercises used to relate theoretical concepts to practical experience. The students will be expected to perform directed reading exercises and self-learning exercises on topics related to Power Electronics. Tutorials will be used to reinforce the module material discussed during lecture sessions. Tutorials also serve as a platform of technical discussions to clarify any queries that arise from directed studies.
