DC-DC converter starts up and operates from a single photocell
by Marian Stofka @ www.edn.com: The bq25504 from Texas Instruments is a good candidate to become a milestone on the road to micro-power management and energy harvesting. A prominent feature of this IC is its ability to start up at a supply voltage as low as 330 mV typically, and 450...

Circuit implements photovoltaic-module simulator
José M Blanes and Ausiàs Garrigós writes: Electronics engineers often use photovoltaic-module simulators to test dc/dc-power converters, inverters, or MPPT (maximum-power-point-tracking)-control techniques. The use of these simulators lets you work in the laboratory with...
