Optimized cell technology reduces overall width of Sinamics Perfect Harmony GH180

Siemens medium-voltage converter

The Sinamics Perfect Harmony GH180 is made up of several cells connected in series to create a medium voltage at the converter output. It features an integrated transformer and is capable of adjustment for a wide voltage and output power range.
The integrated cell bypass in conjunction with cell redundancy enables any optional cell to be automatically bypassed within less than half a second, guaranteeing a high degree of availability and reliability. It's almost perfectly sine-shaped output voltage quality means the Sinamics Perfect Harmony GH180 can be used to operate motors of practically any type – old or new, low or high speed – without any additional stress. As every cell can be simply and quickly exchanged, the converter offers outstanding process convenience and ease of maintenance. The proven medium-voltage converter enables simple commissioning and is also suitable for applications involving cable lengths of several kilometers.
