All motors are generators, the old saying goes, with the caveat that few types are equally good at both modes of operation, and some are downright awful as generators (a classic example being the single-phase shaded pole induction type, used in myriad small appliances the world over). Fortunately, both types of AC motor commonly used… Read more »

A quick guide to automotive DC-DC converter testing
Sponsored by Chroma Systems Solutions An automotive DC-DC converter receives high voltage from the battery and converts it to a lower voltage to power on board devices such as the instrumentation panel, entertainment system, sensors, LED lighting, and any other on board devices requiring low voltage DC power. Manufacture’s strategies in DC-DC converter development include reduction in size… Read more »
New thermoelectric superlattice doubles rate at which waste heat is converted to electricity
Researchers from Hokkaido University and colleagues in Japan and Taiwan have improved the ability to transform wasted heat into usable electricity by narrowing the space through which spread electrons move, according to a new study published in Nature Communications. Currently, more than 60 percent of the energy produced by fossil fuels is lost as waste… Read more »
