Figure 3 shows the arrangement of components for a Pi filter
, which requires two planar capacitor arrays.
With PI filter
realizations, in a multirate filter each delay must be repleaced with K delays.
* Field current regulator with PI filter
(MAN operating mode);
If the power supply uses power factor correction, a differential mode choke is often used in a Pi filter
configuration with metal-film capacitors to reduce the differential-mode noise.
The Mini series is available in both LC and PI filter
configurations from 1 to 13 positions.
All models provide overvoltage and continuous short circuit protection, and they contain an internal input PI filter
It features a 2:1 input voltage range, input-to-output isolation, soft start, an input Pi filter
, short circuit protection, 380k Hz switching frequency, flyback topology and four low-dropout linear regulators.
configurations such as C-R-C attenuate noise in both directions, preventing EMI from going both in and out of the system.
All models feature input pi filters
, input under voltage lockout, output current limiting, and short-circuit protection.
The industry has reached the point where traditional architectures, based upon resistor--capacitor (RC) pi filters
, impose limitations in terms of signal integrity and system robustness, and advanced integrated passive solutions based on a new architecture are required.
