Description

3.1

Area of application

The current-source DC-link converter is used for continuous speed adjustment of synchronous
motors with continuous power above 1 MW. The converter is suitable for four-quadrant
operation without additional expenditure. This means driving and braking are possible in both
directions.
Starting converter
The output frequency typically lies between 0 and 50/60 Hz. The converter is used as a starting
device for the following driven machines, for example:
● Blowers
● Fans
● Compressors
● Gas-turbine sets
● Hydroelectric power generators
● Large synchronous motors on weak power systems
Continuous-duty converter
The output frequency typically lies between 0 and 105 Hz. The converter is used for the
variable-speed drive of the following driven machines, for example:
● Blowers
● Fans
● Pumps
● Turbo-compressors
● Reciprocating compressors
● Extruders and mixers
● Continuous-flow conveyors
● Marine propellers
● Drive in rod mills

Safety concept

The converter and its components are subject to a comprehensive safety concept. When used
properly, the security concept guarantees safe installation, safe operation as well as safe
service and maintenance.
