Converter reduces low-frequency harmonic effects

05.11.2009
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.

Im Focus: Making lightweight construction suitable for series production

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.

Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...

Im Focus: Wonder material? Novel nanotube structure strengthens thin films for flexible electronics

Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.

"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...

Im Focus: Deep inside Galaxy M87

The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.

Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Im Focus: A Quantum Low Pass for Photons

Physicists in Garching observe novel quantum effect that limits the number of emitted photons.

The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...

Im Focus: Microprocessors based on a layer of just three atoms

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.

Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
