Power Systems Design Europe April 2006
The APEC conference and show in Dallas
Texas has introduced a number of innovative
products for Power Management. Power
Integrations presented the PeakSwitch for more
efficient stand by in power supplies. Micrel intro-
duced an 8Mhz converter design where the
inductor reaches a miniaturization that focuses
to serve next generation portables. ZilkerLabs
demonstrated a full Digital Power Management
solution. Linear Technology and Primarion
announced shortly after APEC an alliance to
produce digital point-of-load (POL) products.
Digital Power will be more important as the
amount of supply voltages grow in portable
applications while the different levels of supply
voltages for Micro controllers has the tenden-
cy to go to lower levels.
The chip device structures are still shrink-
ing and as a result power consumption and
supply voltage will be reduced. Our cover story
by Texas Instruments introduces the novel
Buck-Boost converter, a design to reach up to
96% efficiency.
Back to the old world. All of our designs have
to take electromagnetic compatibility in con-
sideration.
The EMV/EMC (electro magnetically com-
patibility) conference in D�sseldorf has shown
that design and early research is important to
EMC subjects. Testing and certifying is the
result to pass the requirements set by laws all
around the world.
The EMC compatibility has to be an integral
part of design. Any electronic power design
is a basic part of EMC considerations
whether as a stand alone supply or drive or
part of a system.
PCIM Europe in Nuremberg will have the
European view of Power Electronics. Europe
has its dominant applications in industrial and
automotive while Asia and specific China has
focus into volume production of power supplies
serving the worlds market.
A short introduction on the upcoming PCIM
Europe conference can be found in the news
here in this issue. The summary of keynote
papers gives you an idea of the topics upcom-
ing in May in Nuremberg at the PCIM Europe
conference.
Module manufactures, drive applications
together with automotive requirements influ-
ence the PCIM. We will see the full line of mate-
rials and manufactures from passives to semi-
conductors up to solution levels.
As it has been a tradition for years, experts
from the Industry will join me for discussions at
the Podium. Here are the details to include in
your plans for visiting PCIM Nuremberg. Hall12,
Booth 353:
Gate Drivers Optimized for MOS Devices
will be on Tuesday, 12:45 to 13:30.
Digital Power and the Application Focus
will be on Wednesday, 11:00 to 12:00.
Passive Components are the Spices in
Design will be on Thursday, 11:40 to 12:40.
The theme of each of the discussions are
chosen to enhance awareness of future steps
into technology and design improvement.
Also, Power Systems Design Europe is locat-
ed at Booth 245 in Hall 12, directly across from
the podium, stop in and see us!
