Announcements and Updates
- If your system did not work during the Expo, you may still submit photographic evidence that your complete system works, by sending this evidence in an email to Prof. Erickson. Emails will be accepted until 5 pm on Monday May 7.
- Grade calculator spreadsheet: an excel spreadsheet that includes weights for all graded assignments, and that you can use to calculate your overall course score.
- Experiment 5 final report is due at 5 pm on Friday May 4 in the D2L dropbox.
Update: 5/3/2018 rwe
This course is an introduction to analysis, modeling, design, and testing of electrical energy processing systems, in a practical laboratory setting. Included are power electronics converters for efficient utilization of available energy sources, and energy sources including solar panels and the utility. The semester experiments plus final design project involve design, modeling, fabrication, and testing of a solar power system.
The laboratory includes portable photovoltaic systems associated with every lab station, including 85 W PV panels, 56 A-hour batteries, 300 W inverters, and other supporting infrastructure. Associated with these systems, students design and build power conversion electronics, with analog and digital control circuitry.
The course begins with basic experiments in:
- Photovoltaic power systems and components
The course will then proceed with design experiments in the following areas:
- A maximum power point tracker using a buck converter and microcontroller
- A dc-dc boost converter with analog feedback
- A single-phase inverter
We will participate in the ECEE Department Expo during the morning of May 3. We will have a competition to see which group has built the most efficient and effective system.
ECEN 5517 involves additional work in power converters requiring deeper knowledge and understanding of power electronics.
This course is offered every spring semester. The instructor for Spring 2018 is Prof. Bob Erickson.
