The new LeitDrive is a state-of-the-art 4Q frequency converter developed and built completely by LEITNER ropeways. The in-house engineering considers application-specific details throughout the whole development process. It enables an unprecedented level of adaptation to customer needs and therefore a highly suited and economic choice for our clients.
LeitDrive is a modular system which covers a power range from 250 kW up to 3.000 kW. Each module is a fully functional unit including a grid and motor side inverter. The custom made, water cooled power stack allows an extremely compact size of only 400 mm width per module. The simple and elaborate mechanical handling simplifies the service.
LeitDrive uses highly efficient, latest generation IGBT’s. Due to the customized power stack the IGBT selection can focus on the application without compromise while at the same time avoiding uneconomic overdimensioning.
In order to operate LeitDrive no installation of cryptic service tools is needed: user access takes place simply by using the built-in web interface. The most common fieldbusses are supported via extension cards. The control algorithm is optimized for the in-house developed generators which ensures to support the application needs at its best and results in unrivaled efficiency rates.
Wind Application Functionality
LeitDrive has been developed considering the wind application from the beginning. Thus, specific wind application functionality is implemented most effectively. The converter provides adapted filter design, reactive power control, low&high voltage ride through, soft braking system (SBSS), sensorless operation and a positioning system for maintenance in order to fullfill grid requirements and other operational needs.
