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 a recent press briefing, Texas Instruments (TI) spoke about low electromagnetic interference (EMI) as a key trend in power management, as it minimizes the interference of power supplies with other ...

Picor, a subsidiary of Vicor Corp., has introduced the QPI-4 active EMI filter for 48 V dc-dc converter applications. Providing attenuation from 150 kHz to 30 MHz, the QPI-4 delivers over 40 dB of ...

The QPI-1, an active electromagnetic-interference (EMI) filter for 48-V dc-dc converter applications, provides over 40 dB of common-mode noise attenuation and over 80 ...

If you're responsible for maintaining quality power at a commercial facility and you've got a problem with harmonics, your best bet is to install a series of active filters. Opting for such filters ...

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 ...

After the ISA converges, the rotor vibration amplitude Vin is gradually reduced. in V drops from 11.74 um to 2.70 um, decreasing by 77.0%. Performing FFT analysis to the rotor displacement, the 1st ...
