Delphi Industry Experts Present 42-Volt Systems Solutions At Power Electronics in Transportation Workshop

    NOVI, Mich., Dec. 5 Four of Delphi Automotive Systems
top engineers will help shape industry trends regarding 42-Volt
systems technology when they participate in the biennial Workshop on Power
Electronics in Transportation (WPET2000) at the Novi Hilton this week.  During
the two-day conference, they will share their insights on technologies that
can help bring optimum, cost-effective solutions for higher voltage systems in
vehicles.
    The workshop, sponsored by the Institute of
Electrical and Electronic Engineers (IEEE) Power Electronics Society and IEEE
Southeastern Michigan Section, focuses on the power requirements in vehicles
and is titled "42-V Power Systems for the Next 100 Years."

    Delphi speakers include:

    * Norman Traub, technology integration manager, will discuss the
      automotive community's efforts to provide standardization and define
      technical challenges facing the implementation of dual and 42-Volt
      electrical systems.  This technical program is scheduled for 1:30 p.m.
      on Tuesday, Dec. 5.  Traub has been integral in Delphi's research and
      development initiatives related to 42-Volt electrical systems.  He holds
      four U.S. patents.

    * Joseph Keller, Ph.D., senior experimental ceramist with the Delphi
      Customer Solution Center, will discuss the progress in the development
      and use of lithium polymer batteries.  The session will take place on
      Tuesday, Dec. 5, at 3:30 p.m.  Dr. Keller has worked on projects
      relating to catalytic converters, spark plug development and lithium
      polymer batteries in his five years with Delphi.  He has authored two
      technical publications, has one trade secret and three patents pending.
      He is part of the Lithium Polymer Battery Development Team.

    * Kaushik Rajashekara, Ph.D., manager of the Energy Conversion group,
      Energenix Center, will moderate a panel discussion, "Is 42-Volts the
      Real Solution for Increasing Power Demands in Vehicles?"  Delphi's Traub
      was requested to be a member of the panel, in addition to
      representatives from Ford Motor Co. and General Motors Corp.  This panel
      will take place on Tuesday, Dec. 5, at 11 a.m.  Dr. Rajashekara will
      also lead a discussion on integrated starter generator systems on
      Tuesday at 3:30 p.m.

      Dr. Rajashekara is responsible for technical direction and management of
      several projects in the area of propulsion systems for alternative
      powered vehicles, such as electric, hybrid, and fuel cell vehicles for
      Delphi.  He was a principle investigator on several of the Defense
      Advanced Research Project Agency (DARPA), Department of Energy, and
      Partnership for New Generation of Vehicles (PNGV) sponsored projects on
      electric and hybrid vehicles.  He holds 11 U.S. patents, and has
      published more than 45 papers in the areas of power electronics, and
      electric/hybrid propulsion systems.  He is a fellow of IEEE.

    * Sayeed Mir, Ph.D. will conduct a technical session on 42-Volt electric
      power steering at 1:30 p.m. on Wednesday, Dec. 6.  His session will
      focus on the positive impact 42-Volt technology has on the design of
      electric power steering systems for use in larger vehicles, such as
      full-size trucks and sport utilities, which require higher power.  Dr.
      Mir is a senior project engineer, currently the lead engineer in
      Delphi's power electronics and motor controls group which focuses on
      electric power steering systems, including steer-by-wire.  Mir has
      authored more than 12 records of invention (ROI) and seven papers since
      1994.

    According to Traub, "Vehicle manufacturers are facing the challenge to
provide more electrical power to vehicles, make the vehicles increasingly fuel
efficient and safer, and offer additional customer features.  Vehicle
manufacturers and suppliers are in agreement that the need for higher voltage
systems is eminent and will certainly be implemented this decade."
    Dr. Rajashekara said fuel efficiency is one of the key drivers for
implementing higher voltage systems.  "Because all belt-driven systems --
HVAC, water pump, power steering -- could be electrically powered with higher
voltage systems, drag on the engine could be reduced.  This reduction of
engine drag could improve fuel efficiency by 5 to 10 percent."
    In addition to the IEEE, the Society of Automotive Engineers (SAE) and the
Massachusetts Institute of Technology (MIT) / Industry Consortium on Advanced
Automotive Electrical/Electronic Components and Systems contributed to the
WPET 2000 Workshop.  Delphi is involved in all organizations, and is a charter
member of the MIT consortium, which was formed by MIT in 1996.
