Description

• The objective of the course is an introduction to power electronics. The principles of static converter structures are covered: uncontrolled and controlled rectification, choppers and inverters. The course is taught using the LTSpice simulation tool.

At the end of this course, students will have knowledge of :- power electronic components: power diodes, thyristors and power transistors.- analysis of static converter operation.- component sizing in compliance with electrical constraints.1. Basic concepts of power and energy 2. Three-phase power on a balanced electrical load 3. Essential properties of diodes, thyristors, MOSFETs and IGBTs in switching electronics 4. Relationships between electrical and mechanical parameters of a rotating electrical machine 5. Simulation of H-bridge and three-phase inverter static power converters inverter 6. Principle of speed variation for asynchronous and synchronous machines

Learning Outcomes AAv (AAv)

• AAv1 [heures:12, B1,B3] : At the end of semester S6, the student will be able to determine the instantaneous and average power consumption and energy stored in a given linear circuit (or described by a statement) including resistive, capacitive and inductive effects.

• AAv2 [heures:18, B1,B3] : At the end of semester S6, the student will be able, in a single-phase or three-phase rectifier circuit, controlled or uncontrolled, to: - determine the waveforms of the voltage/current electrical quantities and the powers from a given diagram*. - record the electrical stresses of the diode (or thyristor) in order to size it.

• AAv3 [heures:20, B1,B3] : At the end of semester S6, the student will be able, in a chopper, step-down or step-up circuit, to determine the waveforms of the voltage/current electrical quantities and the powers from a given diagram*. - identify the electrical constraints of the transistor and diode in order to size them.
