Keysight Technologies has developed an optically isolated differential probing family dedicated to enhancing efficiency and performance testing of fast-switching devices such as wide-bandgap GaN and SiC semiconductors. Validation of floating half-bridge and full-bridge architectures commonly used in power conversion, motor drives, and inverters requires measurement of small differential signals riding on high common-mode voltages. This measurement can be challenging due to voltage source fluctuations relative to ground, noise interference, and safety concerns.

According to Automation-Direct, "Braking resistors don't actually provide braking directly -- rather, they allow a drive to stop a loaded motor faster." Why is this important? Protect your AC or DC drive system from regenerative voltage that can create an over-voltage fault on the drive -- especially with high inertial loads or rapid deceleration.

Dr. Hun-Gi Jung and his research team at the Center for Energy Storage Research at the Korea Institute of Science and Technology (KIST) have announced the development of silicon anode materials that can increase battery capacity four-fold in comparison to graphite anode materials and enable rapid charging to more than 80 percent capacity in only five minutes. When applied to batteries for electric vehicles, the new materials are expected to more than double their driving range.
The batteries currently installed in mass-produced electric vehicles use graphite anode materials, but their low capacity contributes to EVs having a shorter driving range than vehicles with internal combustion engines.
Silicon, with an energy storage capacity 10 times greater than graphite, has drawn attention as a next-generation anode material for the development of long-range electric vehicles. However, silicon materials have not yet been commercialized because their volume expands rapidly and storage capacity decreases significantly during charge and discharge cycles, which limits commercialization. A number of methods have been suggested for enhancing the stability of silicon as an anode material, but the cost and complexity of these methods have prevented silicon from replacing graphite.
To enhance the stability of silicon, Dr. Jung and his team focused on using materials that are common in our everyday lives, such as water, oil, and starch. They dissolved starch and silicon in water and oil, respectively, and then mixed and heated them in order to produce carbon-silicon composites. A simple thermal process used for frying food was employed to firmly fix the carbon and silicon, preventing the silicon anode materials from expanding during charge and discharge cycles.
The composite materials developed by the research team demonstrated a capacity four times greater than that of graphite anode materials (360 mAh/g vs. 1,530 mAh/g) and stable capacity retention over 500 cycles. It was also found that the materials enable batteries to charge to more than 80 percent capacity in only five minutes. Carbon spheres prevent the usual volume expansion of silicon, thereby enhancing the stability of silicon materials. Also, the use of highly conductive carbon and the rearrangement of the silicon structure resulted in a high output.
"We were able to develop carbon-silicon composite materials using common, everyday materials and simple mixing and thermal processes with no reactors," said Dr. Jung, the lead researcher of the KIST team. "The simple processes we adopted and the composites with excellent properties that we developed are highly likely to be commercialized and mass-produced. The composites could be applied to lithium-ion batteries for electric vehicles and energy storage systems (ESSs)."
The research results were published Dec. 18, 2019, in Nano Letters.
