Converter reduces low-frequency harmonic effects
With the new Sinamics G150 Clean Power frequency converter from Siemens Drive Technologies, an energy-efficient drive with high power ratings is available for fans, pumps and compressors or extruders, mixers and mills.
The converter also reduces low-frequency harmonic effects on the system and thus fulfils the high requirements for current and voltage quality placed on mains supplies.
Energy efficiency and process quality are the major arguments for using converters in applications such as pumps, fans, compressors, extruders, mixers and mills. The high power ratings of the converters required for these applications lead to undesired effects on the grid if no appropriate precautionary measures are taken. The new Sinamics G150 Clean Power converter meets both requirements.
Its functions are exactly tailored to the energy-efficient operation of fans, pumps and compressors and simple applications with constant torques. At the same time, the converter features an extremely low harmonic content in voltage and current and thus reduces the low-frequency harmonic effects.
The Sinamics G150 Clean Power combines the advantages of the robust 6-pulse rectifier technology with an integrated passive Line Harmonics Filter compact (LHF compact). With this filter, the converter meets even stringent standards such as IEEE519. And pulse frequency components in line current are also avoided with the LHF compact. With the LHF concept mode of operation, active components are not required and there is no need for complex transformer technology. This reduces wear and tear and thus increases availability. Furthermore, power losses are low, which in turn has a positive effect on the efficiency of the converter.
Thanks to the integration of the filter, the converter is very compact in design. Simultaneously, the line fuses of the converter also protect the LHF compact. Circuit breaker and power contactor disconnect the converter and filter safely from the mains power supply, avoiding the need for costly double installation of fuses, circuit breakers and contactors and for an additional line reactor. This filter solution can also be easily combined with high degrees of protection and integrated safety functions.

An international team of scientists has proposed a new multi-disciplinary approach in which an array of new technologies will allow us to map biodiversity and the risks that wildlife is facing at the scale of whole landscapes. The findings are published in Nature Ecology and Evolution. This international research is led by the Kunming Institute of Zoology from China, University of East Anglia, University of Leicester and the Leibniz Institute for Zoo and Wildlife Research.
Using a combination of satellite and ground data, the team proposes that it is now possible to map biodiversity with an accuracy that has not been previously...
Heatwaves in the Arctic, longer periods of vegetation in Europe, severe floods in West Africa – starting in 2021, scientists want to explore the emissions of the greenhouse gas methane with the German-French satellite MERLIN. This is made possible by a new robust laser system of the Fraunhofer Institute for Laser Technology ILT in Aachen, which achieves unprecedented measurement accuracy.
Methane is primarily the result of the decomposition of organic matter. The gas has a 25 times greater warming potential than carbon dioxide, but is not as...
Hydrogen is regarded as the energy source of the future: It is produced with solar power and can be used to generate heat and electricity in fuel cells. Empa researchers have now succeeded in decoding the movement of hydrogen ions in crystals – a key step towards more efficient energy conversion in the hydrogen industry of tomorrow.
As charge carriers, electrons and ions play the leading role in electrochemical energy storage devices and converters such as batteries and fuel cells. Proton...
Scientists from the Excellence Cluster Universe at the Ludwig-Maximilians-Universität Munich have establised "Cosmowebportal", a unique data centre for cosmological simulations located at the Leibniz Supercomputing Centre (LRZ) of the Bavarian Academy of Sciences. The complete results of a series of large hydrodynamical cosmological simulations are available, with data volumes typically exceeding several hundred terabytes. Scientists worldwide can interactively explore these complex simulations via a web interface and directly access the results.
With current telescopes, scientists can observe our Universe’s galaxies and galaxy clusters and their distribution along an invisible cosmic web. From the...
