Siemens SINAMICS Perfect Harmony provides a reliable solution for critical applications where only one cell per phase keeps running

Siemens SINAMICS Perfect Harmony is a drive technology with 50 proven technologies from the industrial manufacturing field of electric drives in the variable frequency drive product line. This medium voltage AC drive product is designed to provide a reliable solution for critical applications. This can be set up as a modular design by connecting a series of low voltage batteries, which allows the driver to maintain a consistent output should one or more batteries fail.

Siemens SINAMICS Perfect Harmony offers scalable solutions for a wide range of voltages and output powers with phase-shifted secondaries offering 18-pulse or better input harmonic cancellation. In this sub-objective, the medium voltage power output of the VFD drive system is maintained almost constant with the quality of the voltage waveform.

Siemens SINAMICS Perfect Harmony can run without any additional stress, even at the lowest normal operating speed

Siemens SINAMICS Perfect Harmony, powered by Arc Defense Technology for the next generation SINAMICS PERFECT HARMONY GH180, can be implemented in harsh environment drive solutions, offering scalable solutions for a wide range of voltages and output powers – from 2.4–7.2 kV .

Siemens SINAMICS Perfect Harmony can be used as an integral transformer to enable medium voltage drives with a power factor exceeding 0.95, which is often set as a lifetime leader in variable frequency drive reliability. With more than 10,000 drives sold worldwide, SINAMICS PERFECT HARMONY runs stress-free even at the lowest normal operating speeds.

Siemens SINAMICS Perfect Harmony achieves higher reliability and facilitates the most innovative functions of the drive

Siemens SINAMICS Perfect Harmony with variable speed drives has helped various industries around the world achieve higher reliability, facilitating Advanced Cell Bypass to comfortably set control areas. This can be used in their critical processes, even in the harshest operating environments, the driver can isolate the output of a faulty unit and reconfigure old or new, low speed or high speed power sections.

With Siemens SINAMICS Perfect Harmony backed by output voltage quality so close to perfect sine wave shape that the cell can be bypassed without interrupting performance, increased torsional vibration is no longer an issue. Siemens SINAMICS Perfect Harmony also features in the event of a fault – less than a quarter of a second – the power conversion efficiency of the variable speed drive is itself class-leading.

Siemens SINAMICS Perfect Harmony offers these functions and technologies that contribute to Siemens Life Cycle Support

Siemens SINAMICS Perfect Harmony has these features and technologies that help to provide Siemens lifecycle support when starting up a series of multiple motors, pumps or compressors and transferring them to the entire production line. The perfect harmony of this AC-free variable frequency drive is more trustworthy in improving efficiency and reducing costs.

in conclusion
