Aim 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.

Objectives The objectives are: To understand the construction and characteristics of different power electronic devices like Power Diode, Thyristor, GTO, TRIAC, MOSFET and IGBT To understand the working principle of single phase and three phase AC/DC (Rectifiers) Converters. To understand the working principle of Converters. DC/AC( Inverters)and DC/DC (Choppers) To analyze the harmonics present and design the filter for Rectifier and Inverter Circuits. To study the applications of power electronic converters in AC and DC Motor Drives, switch-mode power supply, HV DC link, static var compensator and UPS To understand ECAD tool PSIM to Model and simulate different circuits. To study the protection and thermal aspects of power electronic devices.

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