3.3 Power unit
3.3.1 Product features
The water-cooled thyristor module is an electrical subcomponent that cannot be operated by
itself. You must use the water-cooled thyristor module in conjunction with additional
components to create an operational device.
The ultimate design can be varied depending on the required use:
● Use of different semiconductors from 3" to 4"
– Type T2351N52 (3"); T3441N52 (4") EUPEC or equivalent type
● Integration of two reversible converter bridges in series connection with number of thyristors
in series R=1
– 2×(B6C)A(B6C); 12-pulse output voltage
● One reversible converter bridge with number of thyristors in series R = 2
– 1×(B6C)A(B6C); 6-pulse output voltage
The thyristors are controlled optoelectronically via plastic fiber-optic conductors. The thyristors
are fired via the thyristor electronics.
Structurally the two stacks are installed in parallel in a "clamped assembly". The "open"
modules, degree of protection IP00, stand on insulators and are suppored by welded aluminum
sections.
The modules have a simple mechanical design with relatively few components. This
guarantees a correspondingly high MTBF (mean time between failures) and high reliability.
