BCIT ELEX 4420 – Power Electronics and Renewable Energy Applications
BCIT ELEX 4420 – Power Electronics and Renewable Energy Applications Objective The objectives of this lab are to:
learn how to use the power equipment, including voltage source converter (VSC), variac, load bank, capacitive filter, power analyzer, and digital multimeter (DMM).
observe the behavior of diodes.
learn the behavior of a half-wave rectifier. Safety Considerations and Rules You will be working with high voltages in this lab. The utmost professional behavior and attention to safety concerns are expected. Here are some points that you are expected to respect in the smart grid lab (SW3-2750):
Safety glasses are mandatory when working on live equipment (unless you have prescription glasses)
The default option for the circuit breaker in each station is to be off and locked.
You will be allowed to turn the circuit breaker on only after
your circuit is checked by the lab instructor.
You are expected to attend the labs on time. Any delay will be penalized by mark deduction. You will not be allowed in the lab 20 minutes after the lab start time.
Prelabs are due before the lab start time.
For each lab, you will be working in a group of 2-3 (preferably 2). Each group member is expected to participate equally in the lab experiment.
Group members can use the same data for their lab reports, however separate individual reports are required. Any instance of plagiarism will be penalized based on BCIT’s code of ethics.
No foul play is tolerated in the lab. Equipment
