EEEN40197 - Advanced Power Electronics
Availability - Course (Compulsory/Elective)
|EEEN60192 Principles of Power Electronic Converters|
The programme unit aims to:
Build on the material learnt in the Principles of Power Electronic Converters module by introducing advanced concepts and applications in the area of electrical energy conversion systems. Examples will be taken from More-Electric Vehicles, Electrical Power Systems and Robotics.
The unit will examine Power Electronic Sub-system design including practical aspects required to implement a real system. It will consider
(1) The use of Power Electronics in AC power systems
Facts devices, Ratings of High Power IGBTs and IGCTs, Windfarms, Voltage-sourced and current-sourced HVDC, Techniques for connecting devices in Parallel and Series to boost power ratings, Snubbers.
Two level with series connected devices, Diode-clamped, Cascaded H-Bridge, Flying Capacitor, NPC/H bridge drive, PWM generation for multi-level converter, Rectifier connections for drives (12, 18 & 24 pulse), practical considerations, DQ inverter control, Phase Locked Loops.
(3) Power Factor Correction
Standards, Single-Phase DCM and CCM, Three-Phase DCM
Design of a three-phase battery charger for an Electric Vehicle.
Students will be able to:
Knowledge and understanding
- Select and design appropriate converter interfaces for DC/AC and AC/DC power conversion applications at high power level.
- Select appropriate control schemes and sub-system components.
- Be able to design snubbers and voltage/current sharing systems for power electronic devices
- Understand power quality issues related to AC/DC converters
- Apply physics-based modelling to analyse, explain and design the operation of power electronic converters.
- Simulation and analysis
Transferable skills and personal qualities
- Prepare formal assignment and laboratory report
- Modelling of power electronic circuits
