• 12-pulse supply and machine converters
minimise distortion the supply voltage
and heating losses the rotor due to
harmonics
• matching transformer the converter
output
• changeover switchgear
Optional redundant components:
• thyristors per arm thyristor
bridge
• separate exciter converter for starting
• Cooling ancillaries:
Air-cooling: redundant fans
Water cooling: redundant pump
