| Abstract |
In high current testing laboratories
switching systems with a current capability of up to
100kA rms and a switching accuracy of about one
degree electrical are needed. Mechanical switches
are able to conduct the current, but the variance
of the switching time is too high for such an application.
A silicon controlled rectifier (SCR) is not
able to conduct the desired current for more than
a few milliseconds. Thus the advantages of both the
mechanical switch and the SCR are combined in a
hybrid switch by mounting them in parallel. Single
phase prototypes for 100kA rms were built. The
developed prototypes are described and measuring
results are presented in this paper. |
