Product in detail -- Cycloconverter -- Load-Commutated-Inverters

Drives -- Powerelectronics

We supply Thyristor-Rectifiers, Cycloconverter and Load-Commutated-Inverters (LCI).

The converters are based on our Thyristor-System-Cubicle (B6C-Topology), with a optimized assembly for each application.
Regulary we supply aircooled converters, optional those can be assembled for water cooling.
We use two different sizes of Sysytem-Cubicles, 600mm and 1000mm width.
Features:

Module chassis:
Nominal current up to 4000A
Line voltage up to 1300V

Stack chassis:
Nominal current up to 5000A
Line voltage up to 5000V

Gate-Trigger-Units with Fibre-Optic decoupling
Thyristor-Monitoring

The controll logic and CLC-Loops of our converters and drives are hosted on devices made by Beckhoff-Automation. The trigger-set is done on a special FPGA-Logic-Device.

Our cycloconverters with thyristor stacks are the premium choice when it comes to high performance speed control of heavy induction and synchronous motors with high torque and low stator frequencies. They are implemented as three-phase thyristor bridges in 6 or 12-pulse topology. Perfectly suited for powering of mine winders, rolling mills, grinding mills and excavators due to is rugged design.
