Powering Freight & Transportation - Power Systems Design

Four-Day
Power Supply
Design Workshop
Bordeaux, France at the Mercure Hotel March 30 - April 2, 2009
Learn first-hand from Dr. Ray Ridley, a leading power electronics industry
consultant and researcher. During his 28 years in the industry, he has taught
advanced design to thousands of engineers worldwide.The world’s
leading engineering companies in aerospace, semiconductors and
commercial applications send their engineers to the Workshop
to take their designs to the next level.
The Workshop focuses on theoretical and practical concepts
with hands-on experience. Learn to design, build and
measure switching power supplies in our
state-of-the-art travelling laboratory.
Study theory and design concepts each
morning, and build circuits and magnetics in the
afternoon. Learn how to use POWER 4-5-6,
the world’s most comprehensive design
software and receive your own
personalized copy for attending
the workshop.
Tuition is €2500 and includes training, lab
notes, POWER 4-5-6 software and lunch.
Reservations are now being accepted.
Only 24 seats are available at each workshop.
