Flow batteries show promise for grid-scale storage as, like fuel cells, they decouple power output and energy storage when building a battery: the reactor is sized for power output and the surrounding tanks are sized for energy capacity. Given a low-cost working fluid and big tanks, they could store enormous amounts of energy. Seeking that ...

Wurth has written an application note about balancing series-connected supercapacitors. There are other similar resources on the web, but this one stands out as, alongside the usual resistor, Zener and op-amp circuits, it includes balancing using Advanced Linear Devices’ unusual regulating mosfets, and ADI’s LTC3128 charger and balancer that flips power from the most to the ...

Alpha and Omega Semiconductor has created a 5A electronic fuse IC for sub-power rails in servers. On-resistance is typically 20mΩ. Dubbed AOZ18101DI, they come in 3 x 3mm DFN system-in-packages containing a control IC and back-to-back trench mosfets. The internal mosfets are n-channel, biased using a built-in charge pump. “The eFuse continuously monitors the current flowing ...

ESA is looking into using lasers to send large amounts of data from geostationary orbit to Earth. It operates the European Data Relay System (EDRS) packages from that high altitude – payloads sharing room on commercial satellites – which communicate with a constellation of low earth orbit planet-monitoring satellites called Sentinels. Currently Sentinal-EDRS communication is ...
