This module extends the second year Electrical Engineering 1. We introduce power electronics and consider its application to switched mode power supplies and to speed control of both DC and AC machines.
We examine switching devices, natural and forced commutation, resistive and inductive loads, single ended switched mode converter topologies and calculations of their steady state voltage conversion ratios in continuous and discontinuous inductor current modes.
We look at multiple quadrant switched mode converter topologies including half and full bridge topologies, compare single ended, push-pull, half-bridge and full bridge topologies in terms of required semi-conductor device rating and transformer use.
We also investigate AC -DC converters – 3-pulse and 6-pulse 3-phase, DC chopper, transient performance of DC machines,continuous and discontinuous current operations, the effect of harmonics, distortion power factor.
In lectures we explain the principles, discuss applications and solutions of relevant examples. Then in practicals you use software packages (Pspice & Matlab) to analyse power systems.
You assignments are to report on your laboratory activity.
