Siemens Sinamics Perfect Harmony Variable Frequency Drive
Manufacturer: Siemens

SINAMCIS PERFECT HARMONY variable frequency drive product line features 50+ proven technologies designed to provide a reliable solution for critical applications. The medium-voltage power output of the VFD drive system is created by linking a series of low-voltage power cells, offering a scalable solution for a wide range of voltage and output power from 2.4 - 7.2 kV.

This modular design also facilitates the drive’s most innovative feature, Advanced Cell Bypass, which allows the drive to maintain consistent output if one or more cells fail. In the event of a fault, the drive isolates the output of the failed cell and reconfigures the power section to bypass the cell without interrupting performance — all in less than a quarter of a second. The quality of the voltage waveform remains virtually unchanged even when only a single cell per phase remains operational.
