MAX17061 - 8-line white LED drivers

31.12.2008

An onboard key element and a current controlled voltage step controller are used in this IC to drive an array of LEDs that are 8 parallel rows of 10 LEDs each.

To control the brightness of an individual LED, a current source is built into each row, which ensures the accuracy of current distribution between the rows within + 1.5%. In addition, the MAX17061 provides a precise LED brightness control (DPWM) signal.

The DPWM signal is controlled via PWM communication, via the SMBus interface, or both. Additional application flexibility is guaranteed by setting the PWM conversion frequency with an external resistor.

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 ... >>

Energy from space for Starship 08.05.2024

Producing solar energy in space is becoming more feasible with the advent of new technologies and the development of space programs. The head of the startup Virtus Solis shared his vision of using SpaceX's Starship to create orbital power plants capable of powering the Earth. Startup Virtus Solis has unveiled an ambitious project to create orbital power plants using SpaceX's Starship. This idea could significantly change the field of solar energy production, making it more accessible and cheaper. The core of the startup's plan is to reduce the cost of launching satellites into space using Starship. This technological breakthrough is expected to make solar energy production in space more competitive with traditional energy sources. Virtual Solis plans to build large photovoltaic panels in orbit, using Starship to deliver the necessary equipment. However, one of the key challenges ... >>

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, ... >>

GE Haliade-X Offshore Wind Turbine 26.12.2022

GE Renewable Energy announced that its 12MW+ Haliade-X wind turbine received full type certification for operation up to 14,7MW from DNV (the world's largest independent certification body).

DNV is an internationally accredited registrar and classification society headquartered in Hevik, Norway. Previously, Haliade-X received certification confirming that the turbine can operate at up to 13,6 MW.

The full type certificate is a test of the safety and reliability of the turbines, according to the design specifications (Haliade-X is currently the largest wind turbine with full certification).

The certification process for Haliade-X (14.7 MW) included a series of tests on a prototype located in Rotterdam, the Netherlands. The prototype has been extensively tested since November 2019 and has set several world records for continuous power output in a single day.

“At DNV, we forecast 2 TW of installed offshore wind power by 2050. This development is also linked to larger turbines such as GE's Haliade-X. Increasing the size of the turbines, blades and tower will improve the capacity factors. We are pleased to support GE with our certification services to provide safe and reliable wind turbines that support the growth of wind power,” said Kim Sandgaard-Merck, Executive Vice President, Renewable Energy Certification at DNV

The GE Haliade-X 14,7 MW-220 offshore wind turbine alone can generate up to 76 GWh of gross annual power generation. It has the potential to power the equivalent of 20 European households and avoid nearly 000 tons of carbon dioxide emissions.

The 14,7 MW Haliade-X will be commissioned for the first time at the 3,6 GW Dogger Bank wind farm in the UK, which will be the largest offshore wind farm in the world when completed. It is a joint venture between SSE Renewables, Equinor and Vargronn, located off the east coast of Yorkshire.

Due to its size and scale, Dogger Bank is being built in three consecutive phases: A, B and C. Dogger C will use 87 Haliade-X 14 MW turbines. The first three phases will provide electricity to up to six million homes in the UK (there are about 28,1 million households in the country). In the case of the implementation of the fourth phase, the capacity of the world's largest offshore wind farm will reach almost 5 GW.
