Systems Engineering in the Context of Building Automation & HVAC Control Systems--Experiences using Agile Processes and Systems Engineering - TWIN CITIES C16 CHAPTER on 09-October-2014
Evening Overview: “Building Automation and HVAC Systems, how hard can it be?” A team from the Systems Engineering group at Trane will present the nuanced complexities associated with Systems Engineering in the context of Building Automation Systems and HVAC Control Systems. From hospitals, to retail stores, to restaurants, to office buildings, to schools, to military bases, to “green buildings”, to FDA-compliant environment and process control, today’s Building Automation Systems are much more than the simple thermostat systems of the past. In addition, they will share their experiences with aligning System Engineering Disciplines with Agile Development Teams.

About Trane: Trane, a member of the Ingersoll Rand family of brands, has been in the HVAC business for over 100 years. With their 29 manufacturing locations around the world, Trane is a recognized world leader in air conditioning systems, services and solutions. Over a million buildings across the globe have Trane products installed as part of their HVAC Control and Building Automation Systems. As part of Ingersoll Rand, Trane provides a broad spectrum of technology in their products, parts, services, and solutions that span sensors, equipment, embedded controllers, server systems, mobile devices and cloud computing.

About the presenters:
Alan (Al) Rein - has over 36 years’ experience developing Trane's Building Automation Systems. Al has held a variety of software development, quality, reliability and engineering leadership positions. During this time, he was awarded 5 US patents and was a charter member of the ASHRAE SPC 135, BACnet committee. Al’s current responsibility is to lead the Systems Engineering group for Trane’s Commercial Controls business. In addition, Al is a certified Master Black Belt and has lead the training and deployment of the Six Sigma methodology in Software development at Trane. Al also holds a Master’s degree in Software Design and Development.

Sean McCoy – Sean is a Senior Systems Engineer at Trane. Sean has 12 patents, is a 6-Sigma Black Belt, and has 31 years of experience designing and building software systems; 18 of those at Trane developing Building Automation Systems. Sean’s current assignment is leading the development effort for the Requirements Management, Process Automation, and Test Management tools and migration from DOORS (Rational/IBM) to Integrity (MKS/PTC).

Susan Mairs – Susan is a Systems Engineer at Trane and has led the User Centered Design process for the Controls Engineering organization. Susan has 7 patents in her 17 years at Trane where she has been a designer and developer on the full spectrum of controls software, from thermostats to controller displays, tools to enterprise systems and mobile device apps. Currently she fills the Product Owner role on a team using Agile development methods.

Brian Ohs – Brian is a Systems Engineer / Architect with Trane, embedded with the Tools development team to coordinate systems strategy and integrate products across technical and geographical boundaries. 7+ years of C# .NET development experience focused in controls/building automation systems development including both desktop and web technologies. Focused on the divide between legacy technologies and state-of-the-art solutions. Technical evangelist, pragmatist, and disruptionist.

Matching GaN Characteristics to Power Circuit Topology Maximizes Performance Benefit - TWIN CITIES PEL35 CHAPTER on 16-October-2014
Join the Twin Cities IEEE Power Electronics Society chapter (PELS) for a presentation by Eric Persson, Executive Director, GaN Applications and Marketing, International Rectifier, on October 16 at the conference room of the Mel Foster Company, 7566 Market Place Drive Eden Prairie, MN 55344. We'll start with networking and pizza at 5:30PM.

Summary

Many recent papers discuss the benefits of GaN power switches in various power electronic applications. But the unique characteristics of GaN devices benefit different circuit topologies in different ways. Mr. Persson compares commonly-used power supply topologies like boost PFC, flyback and LLC resonant DC-DC converters implemented with 600V Silicon (superjunction) and GaN cascode switches as primary-side power devices. The key static and dynamic characteristics of the Si and GaN switches are compared and their effect on conduction and switching loss for both hard and soft-switching modes are discussed in detail. In single-ended circuits where the body diode never conducts, switching loss is dominated by device output charge Qoss. Half-bridge based topologies can operate in hard or soft switching, and switching loss can be dominated by either Qrr or Qoss and Qg. Compared to superjunction FETs, GaN cascode switches benefit all of these topologies, but the largest benefit is found in resonant and soft-switched operation where reduced Qrr, Qoss and Qg all contribute significantly to improved performance.

Thank You PES Members!! Free Tour of Target Field - TWIN CITIES PE31 CHAPTER on 02-October-2014
Greetings everyone!

Thanks to the efforts of PES volunteers and support from their family members, the Twin Cities PES chapter has become one of the most successful chapters in the country. Since our chapter has been so active and successful, we would like to offer this event in part to say "Thank You" to all of the PES members that have contributed to making our chapter what it is today. We also would like to welcome the prospective PES members for this free event.

We cordially invite you to join us on a tour of Target Field. The event is scheduled for Thursday, October 2nd at 5:30 PM. The tour cost has been covered by the IEEE PES Twin Cities chapter. So, no cost for attendees. This does not include any food or parking fees.
The tour will begin near the Majestic Pro Shop by Gate 29. Tours typically are 60 to 75 minutes long. Please allow 90 minutes to complete the tour. There is a drop off area on 7th street by the Majestic Pro Shop. Automobile parking is available in the A and B parking Ramps off 7th street between Target Field and Target Center. Commute via light rail or the North Star Train may also be an option for you.

Please RSVP to Steve Nelson if you would like to attend (Steven.R.Nelson@IEEE.org). Attendance is limited to 50 people and is first-come-first serve. Members and prospective-members are invited. There has been some discussion about meeting at a local restaurant afterword for a reception dinner. Please indicate if you are interested in joining afterword’s or have any suggested locations in your RSVP.

Again, Thank-You for your continued support of the Twin Cities IEEE PES chapter, and we hope you will consider joining us for this fun night.

Best regards,
Steve Nelson – PES TC Secretary
