TITLE Power Electronics 1

LEVEL 02 - Years 2, 3 in Modular Undergraduate Course


DEPARTMENT Industrial Electrical Power Conversion

DESCRIPTION Power semiconductor devices, their switching and heat control.
- Mosfets, IGBTs, Thyristors
- Switching waveforms and snubbers
- Heatsink Calculations

Basic Power electronic circuit topologies
Single-Phase Rectifier Circuits: uncontrolled and controlled rectifiers
Three-Phase Rectifier Circuits: uncontrolled and controlled recitifiers
Switch-mode DC / DC converters

Study-unit Aims:

- To provide theoretical background for the analysis of power electronic circuits and to introduce simulation as a design tool of power electronic circuits.
- Covers fundamental principles of circuits used in regulated switch-mode power supplies as well as circuits used in industrial dc drives.

Learning Outcomes:

1. Knowledge & Understanding:
By the end of the study-unit the student will be able to:

- Explain operation of basic rectifier and switch-mode converter circuits assuming ideal power devices: modes of operation, equivalent circuits per mode, voltage and current waveforms;
- Understand basic principles of power semiconductor device construction;
- Explain basic transient characteristics of power semiconductor devices;
- Explain and analyse power loss mechanisms in power semiconductor devices based on first-order models.

2. Skills:
By the end of the study-unit the student will be able to:

- Design basic stages of regulated switch-mode power supplies;
- Predict approximate power loss of semiconductor devices and select suitable value of heatsink thermal resistance;
- Use PLECS package (blocksets for Simulink) for simulation of power electronic circuits.
