Frequency converter

The frequency converter system is designed as a multi-drive system. Thanks to the flexible equipment with Liebherr power modules, an individual drive configuration is possible for a high power range. An energy exchange between the connected drive units takes place through the common DC intermediate circuit. This increases the effectiveness of the complete system.
