Loher DYNAVERT XL wind turbine converter

The Dynavert XL is a converter system for wind turbine systems for double-fed induction generators (DFIG), induction generators (IG), synchronous generators (SG) as well as permanent-magnet generators (PG). All of the filters required as well as the low-voltage switchgear are already integrated into the unit.
The Control-Board 08 (CB08) is the core of the Dynavert XL. Based on state-of-the-art dual processor technology, it controls the complete converter sequence. Starting from the line supply monitoring, through synchronization, fault memory up to defined shutdown when faults occur. The CB08 can master any situation.
