High tension and durability
Development of a high voltage DC power system
With the development described here on the right,
the high-voltage power systems of Ampegon Power
Electronics AG are now in a better position on the
world market.
A 130 kilovolt high-voltage DC power supply with a peak
performance of 39 megawatts in continuous operation
has been developed for the various heating systems of
Wendelstein 7-X. Above all, this power system, which has been
recently expanded to ten modules, must fulfil the high demands
of the microwave tubes. The normal systems available from
Ampegon, formerly Thomson Broadcast, had to be improved in
order to reach the necessary specifications. Most importantly,
the control precision has been improved, while increasing the
voltage range and optimising the quality of the direct current,
in particular the residual ripple.
