Here is a part of ultra-reliable, mission critical power systems that is often understated, but is nonetheless a key component to a robust design—-the surge protection filter. XP Power developed the ...

In the last edition of Don’t Fear the Filter, we built up two examples of the simplest and most-used active filter of all time: the two-pole Sallen-Key lowpass. This time, we’re going to put two of ...

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 ...

The IEEE's Applied Power Electronics Conference (APEC) is a must-go event for designers who need to keep up with the latest power-related technologies, products, and design practices. So, it's no ...

Texas Instruments (TI) has unveiled what it claims is the industry’s first stand-alone active electromagnetic interference (EMI) filter integrated circuits (ICs). Intended to help engineers implement ...

Swedish biomaterials startup Adsorbi has entered the molecular air filtration market with the launch of Arbomax, a new family ...
