Concordia University
Department of Electrical and Computer
Engineering
Power Electronics (I) ELEC-433/6411
Week 1
Review of basic concepts
(Chapter 3)
, Outline of the lecture
• Review of basic concepts:
– Definitions
– Analysis of sinusoidal waveforms
– Analysis of non-sinusoidal waveforms
– Response of an inductor and a capacitor to
pulsed signals
• Power electronic systems: Introduction
– Pulsed versus linear electronics
– Classification of power converters
– Scope and applications
, Conventions
• IEEE standard letter and graphic symbols.
• Units of the International System of Units (SI):
meter (m), second (s), kilogram (kg) etc..
• Italic lowercase letters represent the instantaneous
value of quantities.
• Italic uppercase letters represent average or rms
values
vs (t ) = vs = 2 Vs sin(ω t )
• Bold uppercase letters represent phasors.
, Focus on Steady-state analysis!
• When is a linear RL circuit in steady-state? (NEW!)
