Abstract: In the wound-field synchronous starter-generator (WFSSG) system used in fully or more electric airplanes, the open-circuit (OC) fault of the rotating diode rectifier (RDR) poses a ...

This circuit was designed to meet a medical application’s requirement to drive a laser diode with reasonable precision and a minimum of components and footprint (the device is now in clinical trials).

[Hales] has been on a mission for a while to make his own diodes and put them to use and now he’s succeeded with diodes made of sodium bicarbonate and water, aluminum tape and soldered copper. By ...
