Zero crossing detector circuits

Light Dimmers are devices used to lower the brightness of a light. Light dimmers are generally used to control light output from resistive incandescent, halogen, and sometimes also compact fluorescent lights (CFLs) and light-emitting diodes (LEDs). Dimming LEDs have their own set of challenges and dilemmas. Modern dimmers are built from semiconductors that are often

Fuel Cells Poised to Replace India’s Diesel Generators – IEEE Spectrum

https://spectrum.ieee.org/computing/software/fuel-cells-poised-to-replace-indias-diesel-generators Diesel generators are widely used for decentralized power generation. These generators, although inexpensive, are inefficient and pose great environmental and health risks. Scientists are investigating cleaner, cost-effective, and more dependable technology for powering telecom towers and eventually buildings. A promising answer to the cost and pollution conundrum can be found in proton exchange membrane fuel
