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.
cover 3 types of tests, per site, distributed as follows: - aeraulic characterization of the sampling points of iodine traps (pi) and very high capacity filters (the), - efficiency tests of the and pi filters
, - pi leak tests to be qualified (when their effectiveness is no longer demonstrated and they have been replaced).
All models feature input pi filters
, input under voltage lockout, output current limiting, and short-circuit protection.
Ericsson Power Designer (version 1.4) features advanced loop compensation functionality that makes it easy to simulate output capacitors and filtering networks such as PI filters
on the output of 3E* Point-Of-Load (POL) DC/DC converters, and to optimize loop response without hardware modification for the end application.
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.
