TMdrive-XL85 Adjustable Speed Drive Converter: • Low harmonic distortion • Input from six windings • 36-pulse diode converter Converter (Source) Compartment 1 of 3 phases shown in detail C (W) B (V) A (U) C (W) B (V) A (U) Inverter Compartment Phase-Leg Assemblies Inverter: • Low harmonic distortion • Five-level GCT circuit Synchronous motor for high power levels. Voltage 7.6 kV M Transformer Redundant TMdrive-XL85 Configuration A redundant configuration of the TMdrive-XL85 can be built using four active channels (blocks) connected as shown in the diagram. The system has: • Four transformers and four TMdrive-XL85 channels. • Four parallel connections. • A very clean waveform. • Contacts to isolate any one channel. The redundant function is as follows: 1. A problem is detected in one channel. 2. The suspect channel is isolated and stopped. 3. The three other channels continue operation and deliver full power to the motor. 4. The out-of-service channel is repaired and brought back on line.
