3. Power electronics and cabinet features 3.1. Main features of the drive The water-cooled ACS5000 is a voltage source frequency converter of the ACS product range. It is available for up to 36 MVA and for standard motors with voltages up to 6.9 kV.
POWER ELECTRONICS AND CABINET FEATURES VSI-MF The VSI design employs DC-link capacitors and provides a switched voltage waveform. As a result of the multilevel topology, the drive produces an optimum number of switching levels, ie, 9 levels, phase to phase. The resulting output waveform permits the application of standard motors without decreasing the reliability and efficiency of the motor.
POWER ELECTRONICS AND CABINET FEATURES Fuseless protection concept The drive does not require any power fuses. Instead, the IGCTs of the inverter are used for protection. If an overcurrent occurs, protection firing is triggered and fault clearing is initialized in less than 25 µs. 3.2.
POWER ELECTRONICS AND CABINET FEATURES 3.3. Phase converter unit (PCU) PCUs are available as 6-pulse and 12-pulse rectifiers (Table 2). All drive configurations (FS 1, FS 2, FS 3, and FS 4, Fig. 8) have three primary PCUs, where each PCU supplies a different motor phase.
