Varta has added three smaller button cells to its CoinPower range of Li-ion rechargeable batteries for hearables, other wearables, and other portables. “The provision of energy in a tiny space is playing a growing role in an increasing number of aspects of modern mobility and health,” said the firm. “This is the case with hearables, which are worn on or ...

Liquified gas electrolytes could be the key to batteries that use lithium metal anodes, according to the University of California San Diego. Replacing the carbon anode of lithium-ion cells with metallic lithium could theoretically improve energy density in rechargeable batteries, but they have not become popular because the inclusion of metallic lithium makes the batteries unsafe – particularly as the ...

Power Integrations created an isolated gate drive system for up to four paralleled 1.7-4.5kV power modules – either IGBT or silicon carbide mosfet. Called Scale-iFlex, it is dual channel so, for example, independent control of high and low-side switches in a half-bridge is possible. “The system is optimised for the latest 1,700V to 3,300V rated power modules from all of ...

Three-phase inverter modules from Infineon, are now available from Mouser Electronics. The CIPOS Tiny series of   intelligent power modules (IPMs)  offer high power density for variable-speed motor drives in washing machines, range hoods, room air conditioning and commercial and industrial fans. They are based on Infineon’s Trenchstop IGBT 6 and have a footprint that is 33% less than the earlier CIPOS Mini series. They have ...

Encapsulated power modules from Renesas Electronics are now available from distributor, RS Components. The ISL8210M, ISL8212M, ISL82180M and ISL8282M power modules are single-channel, synchronous step-down power modules that provide PoL conversion for fpgas, dsps, asics and memory in servers, storage, optical networking, telecoms and industrial applications. The modules deliver 10A or 15A continuous current at PoL and combine a pwm controller, inductor ...

At PCIM 2019, we caught up with Mahoro Takahashi of Murata as part of our promotional coverage for the event. Mahoro discusses Murata’s new Micro Battery line-up – the company has released a range of small lithium coin batteries. She describes how new features enable longer battery life for demanding application with higher peak current or higher temperature. Thank you ...
