Press Release14 March 2017Process Industries and DrivesNuremberg

Optimized cell technology reduces overall width of Sinamics Perfect Harmony GH180

Reduced overall width through new printed circuit board (PCB) cell design
20 percent narrower than comparable converters of its class
Improved user convenience due to frontal fan exchange
Proven topology using narrower, lighter cells

The latest generation of the Sinamics Perfect Harmony GH180 series from Siemens marks a significant improvement of this proven medium-voltage converter. The new PCB cell design permitting narrower, lighter-weight cells and a changed transformer design together add up to improved converter output. The new design reduces the overall width of the new Sinamics Perfect Harmony GH180 by around 20 percent compared to similar converters of its class. The new lighter cells can be removed without the need for any aids, and the fan can now be exchanged from the front, making for an enormous improvement in user convenience. Compatibility with almost every motor type makes the medium-voltage converter suitable for wide-ranging applications in fields such as power generation, mining, and the metal, cement, chemical, water, oil and gas industries.

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.
