IGBT Modules for Three Level UPS Inverters

25.07.2008

SEMIKRON has introduced a new topology of miniature IGBT modules of the SEMITOP series for building three-level inverters for uninterruptible power supplies.

The modules are based on IGBTs with low static and dynamic losses, which can reduce the power dissipation level of a three-level circuit by 60% compared to a two-level converter. In addition, the proposed topology provides a significantly lower value of the distributed inductance of switching circuits.

The new modules are designed for use in UPS with a power of 5...80 kVA. The current range of the new modules with an operating voltage of 600 V is 20...150 A. In UPS applications, this allows you to create converters with a power of 5...80 kVA. Modules with three-level IGBT topology are available in two types of packages: SEMITOP3 (footprint 55x31 mm2) for current 20...50 A and SEMITOP4 (footprint 60x55 mm2) for current 75...150 A.

Miniature isolated IGBT modules of the SEMITOP series are 12 mm high and are fixed with a single central screw.

The existence of an entropy rule for quantum entanglement has been proven 09.05.2024

Quantum mechanics continues to amaze us with its mysterious phenomena and unexpected discoveries. Recently, Bartosz Regula from the RIKEN Center for Quantum Computing and Ludovico Lamy from the University of Amsterdam presented a new discovery that concerns quantum entanglement and its relation to entropy. Quantum entanglement plays an important role in modern quantum information science and technology. However, the complexity of its structure makes understanding and managing it challenging. Regulus and Lamy's discovery shows that quantum entanglement follows an entropy rule similar to that for classical systems. This discovery opens new perspectives in the field of quantum information science and technology, deepening our understanding of quantum entanglement and its connection to thermodynamics. The results of the study indicate the possibility of reversibility of entanglement transformations, which could greatly simplify their use in various quantum technologies. Opening a new rule ... >>

New method for creating powerful batteries 08.05.2024

With the development of technology and the expanding use of electronics, the issue of creating efficient and safe energy sources is becoming increasingly urgent. Researchers at the University of Queensland have unveiled a new approach to creating high-power zinc-based batteries that could change the landscape of the energy industry. One of the main problems with traditional water-based rechargeable batteries was their low voltage, which limited their use in modern devices. But thanks to a new method developed by scientists, this drawback has been successfully overcome. As part of their research, scientists turned to a special organic compound - catechol. It turned out to be an important component that can improve battery stability and increase its efficiency. This approach has led to a significant increase in the voltage of zinc-ion batteries, making them more competitive. According to scientists, such batteries have several advantages. They have b ... >>

Alcohol content of warm beer 07.05.2024

Beer, as one of the most common alcoholic drinks, has its own unique taste, which can change depending on the temperature of consumption. A new study by an international team of scientists has found that beer temperature has a significant impact on the perception of alcoholic taste. The study, led by materials scientist Lei Jiang, found that at different temperatures, ethanol and water molecules form different types of clusters, which affects the perception of alcoholic taste. At low temperatures, more pyramid-like clusters form, which reduces the pungency of the "ethanol" taste and makes the drink taste less alcoholic. On the contrary, as the temperature increases, the clusters become more chain-like, resulting in a more pronounced alcoholic taste. This explains why the taste of some alcoholic drinks, such as baijiu, can change depending on temperature. The data obtained opens up new prospects for beverage manufacturers, ... >>

Earth's climate is changing 17.03.2013

According to a study by scientists from Louisiana State University, the Earth, even after the most powerful glaciation, can thaw almost instantly (by geological standards, of course). The culprit in this process is carbon dioxide. Considering that our civilization emits a huge amount of CO2 into the atmosphere, the news about the great mobility of the planet's climate is of particular importance.

Approximately 635 million years ago, almost the entire Earth was bound by ice. This glaciation, known as the Proterozoic, occurred before the advent of life. It was it that led to the formation of the current climatic conditions: with a temperature comfortable for life and a high level of oxygen. Thanks to the Proterozoic glaciation, there was a real explosion in the development of living organisms in the late Cambrian period and, ultimately, man appeared.

Until now, scientists have not understood how the Earth, frozen to the tropics, thawed so quickly and restored the balance between the new atmosphere, hydrosphere and biosphere. To answer this question, scientists conducted a study of the sulfate mineral barite (BaSO4), which has been preserved in rocks since the Proterozoic glaciation. This mineral absorbs oxygen during growth and contains 3 stable oxygen isotopes: O-16, O-17 and O-18. In barite from the time of the Proterozoic glaciation, the isotope O-17 was less than expected. Scientists suggest that this is due to the very high content of carbon dioxide in the atmosphere.

Thus, 635 million years ago, very large-scale changes took place in the atmosphere of our planet. Apparently, they are connected with the fact that the ocean was almost completely covered with ice. As a rule, the levels of carbon dioxide in the atmosphere are in equilibrium with the levels of carbon dioxide in the ocean. However, if water and air are separated by a thick layer of ice, as was the case during the Proterozoic glaciation, the level of CO2 in the atmosphere rises sharply.

Thus, the Proterozoic glaciation ended with a powerful greenhouse effect, which very quickly warmed up the planet and, in fact, prepared a comfortable "sandbox" for the development of the most diverse animal and plant life on Earth. A similar increase in the concentration of carbon dioxide in the atmosphere is observed now, only today it is caused by man-made causes.

The study by American scientists also demonstrates how quickly our planet can recover, even after the most massive and catastrophic events. We can not worry about our planet - it is able to save life and give rise to new species in any situation. True, it is not a fact that the Earth will "take care" of people who themselves will "pull the trigger" of global change.
