Magnetics Business & Technology - November/December 2021 - 19

RESEARCH & DEVELOPMENT
magnets down to this temperature, GSI has built an elaborate,
almost 700-square-meter test facility with cryogenic equipment for
superconducting accelerator magnets. It has four so-called feed
boxes to connect the dipole modules for parallel testing in different
phases. Using a specially procured high-power power supply unit,
the modules could be supplied during the performance test with
amperage up to 17 kiloamperes at rise rates of 28,000 amperes
per second.
At FAIR (Facility for Antiproton Ion Research), matter that usually
only exists in the depths of space will be reproduced in a lab
for research. Scientists will be able to gain new insights into the
structure of matter and the evolution of the universe from the Big
Bang to the present. FAIR is under construction at GSI Helmholtz
Center for Heavy Ion Research. Its existing accelerator
facilities will serve as first acceleration stage.
GSI/FAIR site in Darmstadt
GE's LV8 power electronics platform
The power converters project was awarded in June.
GE will supply low-voltage IGBT inverters from its
LV8 power electronics platform, a high-performance
modular drive for industrial applications that can
address research, development and technical challenges
flexibly. It can be customized for either AC
drives with rotating machinery or DC loads such as
magnetic power supplies, each with single- or multiquadrant
capability. In addition, particularly powerful
IGBT switches are provided for quench protection of
the superconducting magnets. The power electronics
will be implemented with system components such
as power transformers, medium-voltage switchgear,
surge arresters and fast semiconductor fuses.
These new switch-mode power supplies replace earlier
generations of thyristor power supplies with their
fast FET (field-effect transistor) ripple compensators.
Switching power supplies have enhanced functionality,
providing both power current to the magnets
(formerly thyristor power converters) and smoothing
the ripple of the same (formerly FET arrays). The
total power of the switch-mode converters is about 40
MW for the main dipole magnets and their quadrupole
magnets.
" We are proud to be part of this ambitious research
project, requiring our technologically advanced
solutions and know-how. In addition, we are working
with the challenging requirements of both limited
space and reconciling our power converters with the
water-cooling consumption and air conditioning constraints, "
noted Joerg Nuttelmann, general manager
of GE Power Conversion Germany.
