Winter Design Competition!

Hello everyone! We all hope you are having a great finals week and wrapping up a successful semester! To celebrate the spirit of creativity, we are kicking off the annual IEEE Winter Design Competition RIGHT NOW!

Zombies are coming, and you're the only one that can stop them! Build something that will be useful in a zombie apocalypse and compete to win some really great prizes! The competition will be held right when we get back in February, so you can keep yourself occupied for all of Winter Break!

Full contest rules and more information can be found Here.

We look forward to seeing the amazing ideas you guys and gals come up with... but the zombies are coming faster than you think, so get building!

Arduino Workshop 1

Thank you to everyone who attended the first Arduino workshop today! It was great fun for us and it seemed like everyone was excited. We certainly are.

Anyway, the resources from that workshop (PowerPoint presentation, code files, and a complete recording of the session) are now posted on the Open Design Competition Workshop Page.

Advanced Power Electronics and Motor Drives for Future Transportation Electrification

A reminder that the next meeting of the Denver Chapter of the IEEE Power Electronics Society is pleased:

Thursday, 1 May 2014, 6:00 p.m.
University of Denver – Knudsen Hall
Room CMK 309
Denver, Colorado

We are very pleased to host the following Distinguished Speaker:

Advanced Power Electronics and Motor Drives for Future Transportation Electrification
Speaker: Prof. Sheldon S. Williamson
-          P.D. Ziogas Power Electronics Laboratory Concordia University, Montreal, Quebec, Canada
-          Distinguished Lecturer for IEEE Vehicular Technology Society


Currently, the most promising and practical solution to sustainable transportation electrification lies in electric and plug-in hybrid electric vehicles (EVs/PHEVs). An EV/PHEV can reduce fuel consumption by charging its battery from the utility grid, or in the near future, from renewable energy sources (smart grid/micro-grid scenario). Typical battery charging time for EVs/PHEVs is 6-8 hours. Thecharging/discharging EV battery will have a huge impact on the utility. Alternatively, photovoltaic (PV) panels could be used for charging EVs during work hours or at home.

The presentation will initially review current as well as future charging methodologies for EV/PHEV batteries and energy storage systems. The presentation will discuss the modeling, sizing, design, and implementation of a high-efficiency, single-stage, PV-grid-based charging infrastructure for EVs/PHEVs. The novel, single-stage PV/grid charging infrastructure is universal in nature and smartly adaptable, whereby EV/PHEV batteries of different chemistries as well as charging rates can be accommodated in a single power conversion stage. The designed charging infrastructure can support both Level 1 as well as Level 2 EV/PHEV charging. According to SAE J1772 standards, DC charging of EVs can be performed at 200-450 V DC, 36 kW, and 80 A (DC Level 1), and up to 200 A, 90 kW (DC Level 2). This presentation will also focus on system-level aspects of EV charging. Futuristic PV/grid-based inductive and/or surface charging infrastructures will also be presented for EVs and PHEVs. Power electronic converter topologies and energy management systems for such an inductive/surface EV/PHEV charging infrastructure will be presented.

On-board EV/PHEV energy storage issues for batteries and ultra-capacitors will also be highlighted. Li-ion batteries, although popularly proposed, have been highly uneconomic for EV/PHEV energy storage, overshooting cost requirements by a large margin. Li-ion batteries provide a respectable solution for EV energy storage. However, main practical issues include: cycle life, calendar life, energy density, power density, and lately, safety. These issues can be addressed successfully by using a simple approach: a power electronic cell voltage equalizer. The purpose of the second part of this seminar is to demonstrate the role of power electronics intensive battery and ultra-capacitor energy management solutions, to reach the cost break-even point of an EV. The design and implementation of both inductor-based as well as switched capacitor DC/DC converters for Li-ion battery cell-equalization will be discussed. Finally, the design of a novel, cost-effective DC/DC converter for voltage equalization of EV/PHEV Li-ion battery cells will also be presented.

Advanced motor drives for EV propulsion will be introduced. An overview of applications of permanent magnet synchronous machines (PMSM), synchronous reluctance machines (SynRM), and switched reluctance machines (SRM) will be addressed. Advanced motor drive solutions for both PMSM, SynRM, and SRM will be presented. In addition, power electronic converter topologies for drive purposes as well as control algorithms for efficient performance will be discussed in detail for EV propulsion applications. This research seminar will be useful for engineers and managers with entry-level and/or medium-level knowledge of power electronics and motor drives. The talk would also be suitable for engineers with entry level knowledge of power electronics and motor drives applications towards energy storage systems, electric vehicles, and renewable energy systems.
