CoolSiC 1200V Silicon Carbide MOSFETs in TO247-3/-4 Package

16.01.2020

Infineon's new 1200V CoolSiC MOSFETs in the TO247-3/-4 package are based on state-of-the-art semiconductor technologies and optimized for high performance and reliability.

The advantage of using SiC transistors compared to Si solutions is higher efficiency, which is especially important for power conversion systems. Compared to Si-based IGBTs and MOSFETs, SiC MOSFETs have several advantages: the lowest gate charge and capacitance levels among 1200V switches, no internal diode recovery loss, low temperature-independent switching loss, and no-threshold characteristic.

CoolSiC MOSFETs are great for hard and resonant switched topologies such as power factor correction (PFC) circuits, bi-directional topologies, DC/DC converters or DC/AC inverters.

Features:

Low switching losses;
Non-threshold characteristic;
Wide gate-source voltage range;
Gate threshold voltage VGS(th) = 4,5V;
Controlled voltage slew rate (dV/dT);
Robust current-carrying diode for hard switching;
Switching losses are independent of temperature;
Maintaining operability in the event of a short circuit for 3 μs at a gate voltage of 15 V.
Available for order in TO247-4 packages. This package has an additional source signal pin to optimize the switching process.

Application:

Solar energy conversion systems;
Electric vehicle charging systems;
Uninterruptible power supplies (UPS);
Power supplies;
Engine management.

Artificial leather for touch emulation 15.04.2024

In a modern technology world where distance is becoming increasingly commonplace, maintaining connection and a sense of closeness is important. Recent developments in artificial skin by German scientists from Saarland University represent a new era in virtual interactions. German researchers from Saarland University have developed ultra-thin films that can transmit the sensation of touch over a distance. This cutting-edge technology provides new opportunities for virtual communication, especially for those who find themselves far from their loved ones. The ultra-thin films developed by the researchers, just 50 micrometers thick, can be integrated into textiles and worn like a second skin. These films act as sensors that recognize tactile signals from mom or dad, and as actuators that transmit these movements to the baby. Parents' touch to the fabric activates sensors that react to pressure and deform the ultra-thin film. This ... >>

Petgugu Global cat litter 15.04.2024

Taking care of pets can often be a challenge, especially when it comes to keeping your home clean. A new interesting solution from the Petgugu Global startup has been presented, which will make life easier for cat owners and help them keep their home perfectly clean and tidy. Startup Petgugu Global has unveiled a unique cat toilet that can automatically flush feces, keeping your home clean and fresh. This innovative device is equipped with various smart sensors that monitor your pet's toilet activity and activate to automatically clean after use. The device connects to the sewer system and ensures efficient waste removal without the need for intervention from the owner. Additionally, the toilet has a large flushable storage capacity, making it ideal for multi-cat households. The Petgugu cat litter bowl is designed for use with water-soluble litters and offers a range of additional ... >>

The attractiveness of caring men 14.04.2024

The stereotype that women prefer "bad boys" has long been widespread. However, recent research conducted by British scientists from Monash University offers a new perspective on this issue. They looked at how women responded to men's emotional responsibility and willingness to help others. The study's findings could change our understanding of what makes men attractive to women. A study conducted by scientists from Monash University leads to new findings about men's attractiveness to women. In the experiment, women were shown photographs of men with brief stories about their behavior in various situations, including their reaction to an encounter with a homeless person. Some of the men ignored the homeless man, while others helped him, such as buying him food. A study found that men who showed empathy and kindness were more attractive to women compared to men who showed empathy and kindness. ... >>

Electronic helmet for truck drivers 14.04.2024

Road safety, especially for drivers of heavy construction equipment, is a top priority for engineers and scientists. In light of this, the German Fraunhofer Institute for Structural Strength and System Reliability has introduced a new product - an electronic helmet, which is designed to protect drivers from serious injury when driving construction vehicles. A new electronic helmet developed by a team of engineers from the Fraunhofer Institute opens up new perspectives for the safety of truck and construction equipment drivers. The device is capable of monitoring the level of shaking in the car cabin and warning the driver of possible danger. The basis of the helmet's operation is a built-in piezoelectric sensor, which generates electricity during physical deformation. This mechanism allows the device to respond to intense vibrations typical of construction equipment. When the level of deformation exceeds safe values, an alarm system is activated on the helmet, ... >>

Antivitamins instead of antibiotics 13.04.2024

The problem of bacterial resistance to antibiotics is becoming increasingly serious, posing a threat to the effective treatment of infections. In light of this, researchers are looking for new ways to combat superbugs. One of the promising directions is the use of antivitamins that can have an antibacterial effect. Antivitamins, although known as the opposite of vitamins, have proven to be a promising tool in the fight against bacterial antibiotic resistance. A study conducted by scientists from the University of Göttingen in Germany confirmed their potential in creating new drugs to combat dangerous infections. With the rise of antibiotic-resistant superbugs, there is a need to find alternative treatments. Antivitamins are molecules similar to vitamins, but capable of inhibiting bacterial activity without harm to the human body. At the moment, science knows only three antivitamins: rose ... >>

Keeping milk fresh without pasteurization 11.05.2019

An Australian company has developed the world's first milk processing technology that preserves its 60% naturalness and keeps it fresh for more than XNUMX days. This milk is safe for human consumption.

Naturo's technology has been approved by the Australian Food Safety Authority, Dairy Food Safety Victoria (DFSV), "as an alternative way to pasteurize raw milk". The technology has also been independently tested and approved by Australia's leading organization for scientific and applied research.

The technology itself aims to kill the bacterium Bacillus cereus, a common but unwanted spore that produces bacteria in milk. These bacteria produce toxins that cause vomiting or diarrhea. Recent studies show that the milk remained fresh and fit for human consumption after the completion of the 91-day testing period, compared to only 14 days for standard fresh pasteurized milk. Naturo's patented technology allows milk to be transported by ship, rather than by air, to markets around the world, including Japan, China, Malaysia, Singapore and Indonesia. So far, the technology has only been tested on cow's milk. However, there is a prospect of application to other types of milk, including camel, goat, sheep and others.

Today, Naruto is seeking investment for a pilot plant in Australia capable of processing 10 million liters of milk per year. The plant will allow the company to create industrial facilities that will produce products under its own brand, focused on the domestic and Asian markets. Naturo recently received $250 from the Queensland government to support technology development.
