Dynell’s solid-state frequency converter sets a new benchmark in the aviation industry by combining a robust design with the latest plug&play inverter technology called DIM to optimise availability and reduce lifecycle costs. The modular design of all major power electrical components guarantees highest output quality and reduces the mean time to repair to a minimum of less than 5 minutes. On top an efficiency rate of almost 96% allows airports to cut costs by several hundred Euros per year compared to conventional converter units and adds significant TCO savings in the long run.
The Dynell Inverter Module (DIM) is a bidirectional 3-phase inverter module built with the latest semiconductor technology. The same hardware is used for rectifying the mains voltage and for inverting into the 400 Hz voltage– back-to-back operation. The different firmware is assigned via the CAN-address, which is received through the plug-in system on the back of the module. No address configuration is required – just plug & play. Due to the modern design, the size could be reduced to a minimum and it weighs only 9 kg.
The nominal output power of one DIM is 22.5 kVA. This allows scalable output power of the solid-state frequency converters in steps of 22.5 kVA up to 180 kVA. The efficiency of up to 99% of one DIM module leads to an overall system efficiency of almost 96%. This can be achieved with reduced total harmonic distortion approved by TÜV Austria (Input current distortion <2% / output voltage distortion <1%).
