Objectives
On completion of this module students should be able to:-1. demonstrate awareness of modern power semiconductor switching devices, their characteristics and fields of use, and to explain their switching and thermal behaviour;
2. understand switch-mode power supplies with transformer isolation;
3. understand power electronic control principles for renewable energy sources;
4. comprehend 3-phase variable frequency bridge inverters and output control;
5. extend the understanding of the behaviour of a practical 3-phase induction motor drive under a combination of variable-frequency and variable-voltage operation;
6. understand the basics of induction motor dynamics;
7. explain the structures, operations and principles of control of electronically commutated brushless PM and variable reluctance drives.
Syllabus
1. FET, IGBT and MOSFET switches: operational characteristics, limitations, fields of use, switching behaviour and losses, basic thermal behaviour in terms of steady-state and transient resistance.
2. Switched-mode power supplies with transformer isolation: structure, operation, role of energy storage, influence of leakage and magnetising inductances.
3. Power electronic control of photo-voltaic source stand-alone/grid-connected.
4. Three-phase variable frequency inverters: six-step bridge inverter, PWM controlled inverter.
5. Variable speed 3-phase induction motor drives: operation at variable frequency and variable voltage, operation at variable frequency and constant voltage.
6. Basics of induction motor drive dynamics.
7. Brushless permanent magnet motor and variable reluctance motor drives: structure, operation and principles of control.
