Transformer oil, serving both as an insulating medium and a cooling agent, plays a decisive role in transformer performance ...

Molekule is at it again, tweaking their tech to make their products even better. Except this time it isn't a new type of purifier or a software update but the air filter itself. Since Molekule came to ...

Scientists in the Middle East have developed a series active filter to improve power quality in grid-tied PV systems, consisting of an inductor, two capacitors, and four transistor-diode pairs. The ...

In reliability engineering, few indicators are as consistently revealing as the particles that infiltrate a lubrication system. Long before vibration, temperature, or performance changes become ...

A new IC-based approach to EMI filtering in ac-dc power subsystems dramatically cuts inductor size and offers other benefits as well. The nature of the EMI problem in ac-dc supplies and its ...

Electromagnetic interference (EMI) has a reputation for being one the most difficult aspects in power-supply designs. I think that this reputation comes, in large part, from the fact that most ...

Why a tunable GHz-range filter is needed. How a new approach to devices based on YIG and magnetic spin waves offers a much smaller and lower-power solution. How the new device was implemented along ...
