SIMOREG DC-MASTER Converter Commutation Protector (CCP)

As supplement to the series of SINAMICS DCM converters, we offer the SIMOREG DC-
MASTER Converter Commutation Protector (SIMOREG CCP).
Area of application
The SIMOREG DC-MASTER Converter Commutation Protector (SIMOREG CCP) is used to
protect the semiconductor fuses of a line-commutated converter when operating in the
inverter mode.
When an inverter commutation fault occurs, a high current flows in the regenerative
feedback direction via the line supply or a cross-current in the converter. SIMOREG CCP
limits the current to a non-hazardous value so that the thyristors and the associated super-
fast fuses are protected. This therefore eliminates the complex replacement of fuses that
takes a considerable amount of time. Although it cannot prevent inverter commutation faults,
it can protect its effects.
Compatibility
The SIMOREG CCP is compatible to line-commutated SIMOREG DC-MASTER converters
(6RA70 series) and SINAMICS DCM. It can be used for converters connected in parallel.
Using the SIMOREG CCP
The SIMOREG CCP is operated (parameter assignment, fault signals) is realized via the
SINAMICS DCM. The SINAMICS DCM must have a software release of 1.2 or higher.
For a parallel connection of SINAMICS DCM units, a SIMOREG CCP must be used for each
SINAMICS DCM. In this particular application, each of the SINAMICS DCM must be
equipped with a Firing Unit Trigger-Board. The input for the "fast pulse inhibit interface" is
implemented there.
For ordering data, see also the section titled "Ordering information for options and
accessories".
The operating instructions for the SIMOREG CCP are included on the DVD "SINAMICS
DCM documentation". These operating instructions also include
● help to select the suitable SIMOREG CCP
● the instructions to install the Firing Unit Trigger-Board in the SINAMICS DCM
● the instructions to operate the SINAMICS DCM with the SIMOREG CCP
