ABSTRACT
This volume presents the proceedings of the fifth specialized course organized by the CERN
Accelerator School, the subject on this occasion being power converters for particle accelerators. The
course started with Lectures on the classification and topologies of converters and on the guidelines for
achieving high performance. It then went on to cover the more detailed aspects of feedback theory,
simulation, measurements, components, remote control, fault diagnosis and equipment protection as
well as systems and grid-related problems. The important topics of converter specification,
procurement contract management and the likely future developments in semiconductor components
were also covered. Although the course was principally directed towards DC and slow-pulsed
supplies, lectures were added on fast converters and resonant excitation. Finally the programme was
rounded off with three seminars on the related fields of Tokamak converters, battery energy storage
for electric vehicles, and the control of shaft generators in ships.

FOREWORD
Particle accelerators touch many disciplines and technologies and the CERN Accelerator School
(CAS) tries to reflect this diversity through its specialized courses. The most recent of these was held
in Montreux, 26-30 March 1990, and focused on DC and slow-pulsed power converters for particle
accelerators.
Accelerators and power converters have always been closely associated. In fact the first
accelerator capable of nuclear physics research, built by Cockcroft and Walton, was mainly an
exercise in building a high-voltage power converter. Such was the success of their solution that the
Cockcroft and Walton Generator became the preferred pre-injeetor for large accelerators for many
decades after. Today, power converters have diversified into all the subsystems of large accelerators
and proliferated, until in a machine like LEP there are literally hundreds of independent converters
powering the guide field alone. The consequent demands made on reliability and performance have
been a major driving force in the development of these devices.
The course presented in these proceedings is the result of a serious effort by the very many
people involved. The continued support of the CERN Directorate for the CAS courses and the
guidance of the CAS Advisory and Programme Committeesp are both essential and much appreciated.
The Local Organizing Committee ensured that the course ran smoothly, and many of the CERN
services contributed in one way or another to its success and the publication of these proceedings.
Very special thanks are due to the lecturers, for the tremendous effort they put into preparing,
presenting and writing up their topics. The sponsorship of Holec Innovation and Technology,
Holland, was most appreciated as was the efficiency of the Hyatt's Conference Centre staff. Finally,
the greatest encouragement to all concerned came from the fact that some 80 students attended the
course, representing the accelerator laboratories, universities and industrial firms of no less than 16
different countries.
