ELEC 4440 Power Electronics Bonus UG Project Guidelines

In class, we discussed Power factor correction done using power electronics as shown in the circuit/block diagram below. For this project, do the following:

1. Simulate the circuit using Matlab or any software of preference 2. Show the source voltage and current waveforms before and after correction 3. Send the simulation files to me by May 1st. The report should also be submitted with an

abstract, a short introduction, discussion of results, and conclusions.

This bonus project, when done completely and correctly, will add 5% to your class average.
