Siemens is building the world's largest high-speed variable frequency drive(SINAMICS PERFECT HARMONY GH180)

Siemens Energy and Automation announced that its RobiconPerfectHarmony drive has reached a new level of technology by launching an 8MW variable frequency drive (VFD). This drive has an output frequency of 500Hz, which will make it the world's largest high-speed variable frequency drive. This landmark new product is the latest product of Siemens' high-speed RboiconPerfectHarmony drive series. Although this high-speed inverter technology was previously limited to output frequencies between 120Hz and 200Hz, the operating frequency of the drives that Siemens has already begun to manufacture and install will reach between 315Hz and 400Hz. The RobiconPerfectHarmony battery-powered multi-level design of Siemens provides a unique shape for the product, which enables the product to be used at a frequency of 5

Although this high-speed inverter technology was previously limited to output frequencies between 120Hz and 200Hz, the operating frequency of the drives that Siemens has already begun to manufacture and install will reach between 315Hz and 400Hz.

The RobiconPerfectHarmony battery-powered multi-level design of Siemens provides a unique shape for the product, which enables the product to reach a frequency of 500 Hz when in use, regardless of the power of the inverter. The control test of the inverter in the non-decoded vector control with 920Hz IGBT switching frequency shows that the product provides an effective 9.2kHz switching frequency and a sample frequency of 9.2kHz. This test drive shows high-quality waveform characteristics.

This latest frequency converter will be used to drive by permanent magnet motors, such as for natural gas processing and transportation applications that require high-speed compression. Siemens is one of the few companies that can design inverters with small and more effective permanent magnet motors.
