The new SiC MOSFET module is part of ON Semiconductor’s electric vehicle charging ecosystem and is designed to be used with driver solutions such as NCD5700x devices. The recently introduced NCD57252 dual-channel isolated IGBT/MOSFET gate driver provides 5 kV electrical isolation and can be configured to work as dual lower bridges, dual upper bridges or half bridges.

NCD57252 is available in a small SOIC-16 wide-body package and accepts logic level inputs (3.3 V, 5 V and 15 V). This high-current device (at Miller platform voltage, source current 4.0 A/sink current 6.0 A) is suitable for high-speed operation with a propagation delay of 60 ns.

ON Semiconductor’s SiC MOSFET complements new modules and gate drivers. Compared with similar silicon devices, it has switching performance and enhanced heat dissipation, resulting in higher energy efficiency and power density, improved electromagnetic interference (EMI), and reduced system Dimensions and weight.

Again, Russia intends to withdraw from the ISS project after 2025. By then, Moscow plans to build its own orbital station for the purposes of scientific research. Previously, Deputy Prime Minister of the Russian Federation – Mr. Yuri Borisov said that the situation related to the “aging” of the ISS structure could lead to dire consequences. So Russia should create an alternative to the current project as soon as possible and not leave the astronauts at risk. In addition, Borisov added that the national orbital station in the future could become “high orbit” (located above the ISS), not only used for scientific research but also acting as a “transit base” in the mission to conquer the Moon. Russia will use the ISS international space station’s energy supply module for its future space facility As for the Science and Energy module, work on creating it started in 2012. As planned, by 2015 the device is expected to ensure energy independence for the Russian subdivision on the ISS. . However at that time only the draft design of the device was ready. NEM’s ground tests only really begin in 2018. While its launch is being delayed, Russian scientists will have to be more active in the near future as time is on. increasingly hurry. It should be noted that in addition to the NEM that will become the main module, according to Dmitry Rogozin, two permanent working modules named “Nauca” and “Prichal” could become part of the space station in the future, both modules will sent to the ISS this year.

In April alone, ISS has been busy with flights up and down. On April 9, the Russian Soyuz rocket sent 1 American astronaut and 2 Russian astronauts to the ISS laboratory 420km from the Earth’s surface. Eight days later, another Soyuz rocket carried another trio of American and Russian astronauts back to Earth. On April 23, the US spacecraft SpaceX brought two more Americans, one Japanese and one French to connect to the ISS. However, such bustling scene on ISS is about to come to an end. Last week, Russia announced it would withdraw from the ISS by 2025. Despite the growing tensions between Russia and the US over the past decade, the two countries ‘space agencies continue to work closely with each other, along with 13 countries’ space agencies. According to the US Aeronautics and Space Administration (NASA), since 2000, ISS has welcomed 243 people from 19 countries. According to the Financial Times, Professor Anu Ojha, director of the UK National Aerospace Institute and an advisor to the European Space Agency (ESA), said: “I only hear positive things about astronauts and astronauts as they work together “. In the early years of building and assembling modules of ISS, since 1998, Russia and Western partners cooperated closely. “NASA and ESA cannot build a space station without Russian experts,” said Ojha. The Russians are masters of building modular space stations ”. The ISS station once welcomed astronauts from many countries Western countries need Russian rockets to carry materials and people to and from the ISS. This reliance increased when NASA decommissioned the space shuttle fleet in 2011 and Soyuz became the only passenger vehicle that could put astronauts in orbit. Only in 2020, NASA will begin to use the SpaceX spacecraft system of billionaire Elon Musk. For the Russian Space Agency (Roscosmos), cooperation with the West through the ISS also adds to the financial resources. NASA spent $ 3.9 billion to hire Soyuz to transport astronauts to the ISS from 2011 to 2019. Although astronaut Mark Vande Hei’s trip to the ISS in April may not be the last of an American on Russian rockets, the majority of non-Russian astronauts will travel on SpaceX or on Boeing’s Starliner, expected to go into service from 2022. During the first 15 years, the ISS crew focused on assembly and engineering work, which meant that the zero gravity work environment was only just being established. Recently, NASA astronaut Kate Rubins, who just returned to Earth in mid-April, recounted her hundreds of hours on the ISS to do biological experiments, from decoding DNA on a space station to growing human heart tissue and vegetables. . ISS’s most important area of ​​research is its attempt to understand the long-term effects of space travel on human health, in preparation for planned attempts at the Moon or travel to Mars. Other direction of cooperation For Russia, the decision to end ISS participation is expected to lead to more spatial cooperation with China. It is also part of the Kremlin’s broader pivot to Beijing. Since Western sanctions were first imposed on Moscow in connection with Russia’s annexation of Crimea in 2014, Russia has doubled down on its efforts to strengthen ties with China. The two countries reached agreements on defense and space cooperation while bilateral trade nearly doubled compared to 2010, reaching $ 110 billion in 2019. In 2020, Roscosmos rejected an offer from the US to join NASA-led Artemis program, aimed at bringing people to stay longer on the Moon. In March, Russia and China agreed to jointly develop a base on the Moon to “promote the peaceful discovery and use of space for all mankind” (according to a memorandum of understanding between the two. country). Roscosmos last week also said it aims to set up its own Russian space station by 2030, using modules designed like the ISS. The Interfax news agency quoted Roscosmos Director, Dmitry Rogozin, as saying: “It is likely that by 2030, we can put a space station into orbit, that will be a huge breakthrough.” On Russian television, Deputy Prime Minister Yuri Borisov said that in the future, on the Russian space station, in addition to astronauts, there will be the participation of artificial intelligence and robotics. He stressed that Russia is ready to consider for foreign crews to visit, but definitely the Russian space station must be national. Interfax quoted an unnamed source as saying that Russia planned to spend up to $ 6 billion to put this project into operation. China will also soon introduce the module to build the China Space Station (CSS). The ship carrying this module is scheduled to take off at the end of April. This is the culmination of the project that the Chinese government launched in 1992. After this module goes into space, China plans to launch at least 10 more times. Another launcher carries the remaining modules and cargo to complete the CSS assembly by the end of 2022. The 100-ton, T-shaped CSS will consist of three main modules: the 18-meter core module, called Tianhe, and two 14.4-meter lab modules, called Wentian, that are permanently attached to the sides. of the core module. As the station’s control and control center, Tianhe can accommodate 3 astronauts with a stay of up to 6 months. CSS has volume less than 1/4 the volume of ISS. Instead, configure 3 modules based on China’s need in doing the necessary scientific experiments. The 440-ton ISS with a construction cost of $ 150 billion will end its lifespan and should be returned to Earth expected by 2025. The future of the ISS is still under negotiation after the current cooperation agreements expire. by the end of 2024. According to NASA, from a technical point of view, the ISS can operate until the end of 2028. Of course, the ISS will be upgraded if it wants to last longer, especially electrical and communication systems. .

Increase Armata. “With AI, Russia has created the world’s leading heavy and real robotic tanks. Armata can analyze the situation on the battlefield by himself to attack the most valuable target. After analysis, the vehicle has. can be fired automatically without the intervention of the crew or control center. What is special is that despite the integrated automatic operation, all the power and combat capabilities on the original Armata tank remain the same, “said General Manager Sergei Chemezov. According to the Russian general manager, the new Armata with standards on technical characteristics – tactics, loading system, cockpit structure and support equipment for firing control new. Armata will be equipped with a fully automated combat module that allows the turret to be used differently from traditional tanks. Meanwhile, Deputy Director of Tractor Plants Group (the unit assigned to design Armata), Mr. Mikhail Levshunov confirmed, Armata tanks will be equipped with an automated system that can automatically destroy the target. Select and it will shoot itself until the target is destroyed. He said that the remote control module research was conducted in the framework of research and manufacture of new army technical equipment models. Accordingly, the automatic system can destroy targets in the air and on land. Thanks to the heat detector, it can work all night, when it’s rainy and foggy. Especially while Russia is very confident about the combat strength of the Armata tank, the leading American magazine National Interest pointed out the backwardness of the artillery on both these tanks and the artillery of this tank. the tank front armor of modern Western tanks could not be penetrated. According to an analysis by American magazine, the main reason to say the 2А82 cannon of the Т-14 Armata is outdated is that it uses the same 125 mm size as the previous generation tank cannon. According to some sources, the artillery system was originally built to be fitted with modernized Т-90 tanks that were only intended for the Russian army. After that, with the development of the standard heavy chain chassis Armata, it was decided to equip the next generation tank. The barrel 2А82 is treated to increase elasticity and partially chromed, which greatly increases the durability of the cannon. This cannon can fire existing and future ammo types. Future ammo types could destroy not only existing tanks but also their future variants, as well as new tanks in development. Currently, Russia is testing advanced smart artillery shells for the Т-14, so the ability to destroy enemy tanks is even higher. Although the West underestimated, but the tank manufacturer Armata asserted, the barrel energy of the gun 2А82 is 1.17 times higher than that of NATO’s best cannon, the 120 mm L-55 gun. The Russian artillery is superior to all current tank guns 1,2-1,25 times in terms of technical level and penetrating ability.

“We cannot risk the lives (of the astronauts) … The structures and metals on the ISS (are) getting old, possibly leading to irreversible consequences,” Borisov said. Disaster is waiting to happen. Borisov announced that Russia would withdraw from the ISS by 2025. However, he later delayed the time because the country needed to check the technique, decide and inform partners of the plan to build a new space station. A module of a new space station is under development in Russia. Photo: Roscosmos. The Russian Space Agency (Roscosmos) also confirmed that it is developing a successor space station for Salyut and Mir, two space stations launched into low-Earth orbit by Russia in the 1970s and 1980s. know that agreements with international partners related to ISS will expire in 2024. Share on television, Borisov said that the new Russian space station will orbit the Earth at high latitudes, helping to see the polar regions better. He leaves open the possibility of inviting foreign countries to participate in the construction of the space station. In the video posted to the Internet, Dmitry Rogozin, the director of Roscosmos, said that the first module of the space station is under development, possibly in 2025. Interfax Modules assembled by Energia cost about US $ 5 billion. Still, the prospect of a complete Russian space station is far from over. Andrey Ionin, a member of the Russian Space Academy, said that the new space station would be “a step backwards”. “ISS’s greatest achievement is not technology, but international cooperation,” said Ionin. Before building the new space station, Roscosmos still has to bring the Nauka scientific module to the ISS at the end of the year. Rogozin said Russia will not withdraw from the ISS until the completion of the new space station. However, the announcement from Deputy Prime Minister Borisov will put great pressure on the US Aerospace Agency (NASA) and its partners. Russia believes the ISS is degrading. Photo: Roscosmos. Space stations over 20 years old have regularly recorded incidents in recent times. In March, Russian astronauts patched a gas leak on the ISS that has existed since 2020. This is not the first time Russia has complained about the ISS. Speaking at the Russian Academy of Sciences in October 2020, Vladimir Solovyov, who is in charge of Russian flights at the ISS, thinks the space station will deteriorate rapidly in the next five years, advising the country to prioritize building. new universe. “The ISS partners will have difficulty maintaining the space station without Russia,” said Vitaly Egorov, the space industry watcher. Science . The magazine says SpaceX’s astronaut transportation services can fill the void left by Russia. Two astronauts installed the support frame outside the ISS station Two NASA astronauts step outside of the International Space Station (ISS) to install supports for new solar panels.

Astronauts have had to find a way to fix the leak due to cracks in some modules. Mr. Vladimir Solovyev, Deputy Director of Energia in charge of ISS of Russia in November 2020, said that some components of the ISS station were damaged, could not be replaced and would stop working after 2025. Energia is currently researching. to build a space station named Russia Orbital to replace ISS. The ISS was commissioned in 1998. The life cycle of this space station has been extended to 2020 and then to 2024. Dmitry Rogozin, the head of Russia’s Roscosmos space agency, said after the ISS was shut down, the Progress cargo spacecraft would pull it out of orbit. Then, the ISS will fall into the ocean like the Russian Mir space station when decommissioned in 2001./.
