Power Electronics Conference Simplifies Design Decisions

Power electronics professionals are constantly pushing for designs that are smaller, cheaper and more energy efficient. This year's Power Electronics Technology Exhibition & Conference will provide the tools you need to optimize every element of the design process.

From the large number of technical sessions focused on practical design solutions to the full contingent of suppliers who will be demonstrating their latest innovations and answering questions, organizers of the show have big plans for Dallas, Oct. 28-Nov. 1.

General Session and Keynote Speakers

On Tuesday, Oct. 30, from 9:45 a.m. to 10:45 a.m., Roger Tipley, senior technologist/engineering strategist with HP and a board member of The Green Grid, will present his keynote address on “Opportunities for Energy-Efficiency Innovation in the Power Electronics Industry.” Tipley will provide an overview of The Green Grid, a global consortium of companies dedicated to advancing energy efficiency in data centers and computing ecosystems. Attendees will hear about opportunities to improve efficiency throughout the supply chain of energy.

Immediately following the keynote address, Power Electronics Technology editors will present the magazine's prestigious Lifetime Achievement Award to Ed Bloom for his extensive record of innovation in magnetics design and for championing power electronics education (see page 44 for more on Bloom). Editors also will bestow the highly regarded Product of the Year award to one company. This distinction recognizes a single outstanding product that has significantly advanced the state of the power electronics art.

On Wednesday, Oct. 31, from 9:45 a.m. to 10:45 a.m., Thomas Valliere, vice president and cofounder of Design Chain Associates, will present the General Session, an “Update on China RoHS.” He will compare the European Union's RoHS directives with China's.

Leading-Edge Education

Power Electronics Technology editors Ashok Bindra and David Morrison directed the content for this year's conference, selecting courses, seminars, papers and keynote presentations to bring designers up to speed on the latest developments in the power electronics field. This year's technical paper sessions should entice designers with new session topics and an attendee-friendly schedule. (See pages 52-53 for the schedule of presentations.)

The conference will kick off on Sunday, Oct. 28 with a two-day educational program offering engineers a variety of full-day or half-day professional advancement courses (PACs) focused on specific aspects of power electronics design. These courses will provide intense training in numerous topics such as control techniques for power supplies and motor drives, power device selection, magnetics design and thermal management.

Other PAC topics include modeling/simulation, pc-board layout and design for reliability. Power-supply designers contemplating a move to digital control may want to attend the session on digital power conversion (PAC 06), while those interested in low-power applications may find the new session on energy harvesting (PAC 11) to be beneficial.

On Tuesday, Oct. 30, three days of technical sessions and seminars will begin. The schedule for this year's technical sessions and seminars has been completely reformatted for the convenience of attendees. The schedule is now organized along five tracks: Design Techniques I and II, Components, New Applications and Innovative Applications. This track-based schedule will help attendees to participate in more of the sessions that interest them by avoiding scheduling conflicts for papers in related subject areas.

The New Applications track features first-time sessions on timely topics such as emerging applications, power management for alternative energy, supercapacitors/ultracapacitors and LED lighting. Although only one session bears the title “emerging,” this label truly applies to all of the sessions in this track with its numerous papers discussing power conversion requirements, component technologies and design methods for powering new applications.

Meanwhile, the track on Innovative Applications presents papers in two established but growing application areas: medical power supplies and automotive applications. Because of the highly competitive nature of these applications, power system design information can be difficult to come by, making the papers in these sessions all the more compelling. This track also includes a session on market trends, which presents data on application-related trends that are shaping power component and power system development.

In parallel with the application tracks are the two tracks on Design Techniques and Components that address control techniques, circuits, system architectures, simulation and motor drives, with numerous papers discussing advances in these areas. A highlight of Design Techniques I is the timely session on digital power conversion, while those who attend Design Techniques II get a double dose of magnetics with two paper sessions devoted to magnetics design.

Those looking for compelling advances in component technology may be drawn to the Components track with its papers on power semiconductors and sessions devoted to thermal management design, power modules and portable power management.

Activity-Packed Exhibit Hall

The exhibit hall will offer a wealth of information. With nearly 80 exhibitors signed up, this is a unique opportunity to see and touch products first hand and ask the complex questions you're not going to get answers to from catalogs or advertisements.

In addition to talking face to face with exhibitors, attendees won't want to miss the informative supplier presentations and Ask the Expert sessions that will be held in the Product Solutions Theater inside the exhibit hall. Attendees also can get an up-close look at the new Vibration Energy Harvester by Ferro Solutions and learn about power management solutions in mobile phones from Freescale Semiconductor in these and other exciting product teardowns.

With so much to see and do, plan now to join your colleagues at the Power Electronics Technology Exhibition & Conference for the most idea-filled days of the year. For complete conference information or to register, visit www.powerelectronics.com.
