Passive Components: Recent Advances in Thick-Film Resistors and Target Applications
Thick-film resistors are the preferred resistor type for a wide range of industrial and consumer applications, including current detection and overvoltage protection, due to their relatively low cost. Unlike thin-film resistors, which are similar in appearance, thick-film resistors have contrasting properties and manufacturing processes. And, as their names imply, another key … [Read more...] about Passive Components: Recent Advances in Thick-Film Resistors and Target Applications
Women in Engineering: The Roaring 20s: A Decade Helping Reshape the Face of IEEE PELS
Looking back, 2020 was a year of great reflection for many of us—an opportunity to re-evaluate some of our patterns and make decisions on how we want to invest our time moving forward. While the world waited for the end of a pandemic, the IEEE Power Electronics Society (PELS) Women in Engineering (WiE) committee made important strides towards reshaping our strategy for … [Read more...] about Women in Engineering: The Roaring 20s: A Decade Helping Reshape the Face of IEEE PELS
Expert View: Chemistry Options for Lithium-Ion UPS and BBU
Industrial rack-mounted uninterruptible power supplies (UPS) or battery backup units (BBU) are used in data centers or telecom central offices to provide backup power for servers and switching equipment in the event of power failure. Historically, these UPS’s have relied on lead-acid as the predominant battery type. Currently, lithium-ion (Li-ion) batteries are gaining market … [Read more...] about Expert View: Chemistry Options for Lithium-Ion UPS and BBU
