Description
The FLT-100V series of passive fi lters are optimized to reduce both common-
mode and differential-mode noise on both input and output lines of switching
DC/DC converters. The FLT-100V10 is rated for 10A of continuous current while
the FLT-100V20 is rated for 20A.
Differential-mode and Common-mode Noise
Designers who are faced with reducing conducted emissions in DC/DC
applications must address both differential-mode and common-mode noise.
Differences measured between the two input lines of the DC/DC converter are
classifi ed as differential noise. The dominant contribution to differential noise is
the switching action of the DC/DC converter. Consequently, the majority of noise
will be seen at the converter’s switching frequency and it’s harmonics. The
FLT-100V series fi lter uses a mylar, self healing, 100Vdc rated input capacitor
connected between the two input lines (traditionally referred to as “X” capaci-
tors), in conjunction with the leakage inductance of the common mode chokes to
attenuate the low-frequency differential noise. In addition to the fi lter, a low-ESR
input capacitor (C1 of Figure 4) is also recommended at the input to the DC/DC
to provide a low source impedance and additional noise attenuation.
See typical performance curves for differential-mode insertion loss performance.
Common –mode noise is measured as variations between the input lines (in
common) with respect to the Ground pin. Common-mode noise is gener-
ally in the high frequency spectrum (>10MHz) and originates in the switching
components of the DC/DC converter. A capacitor from each line to the ground
pin (referred to as “Y” capacitors), connected between the two common mode
chokes, provides attenuation of this unwanted common-mode noise. This
ground pin should be connected to a relatively quiet chassis ground point inde-
pendent from the DC/DC converter case connection. Note that a noisy chassis
ground can inadvertently introduce common noise into the system. Some
DATEL DC/DC converters are designed with an internal input-to-outptut capaci-
tor to reduce common-mode noise generated from within the converter. In addi-
tion, common-mode noise can be reduced with the addition of external ceramic
capacitors of 0.1μF to 1.0μF (C2 thru C4 of Figure 4) installed from inputs and
outputs to a shield plane connected to the DC/DC case; safety standards may
limit the size of these capacitors for some applications. See typical performance
curves for common-mode insertion loss performance.
FLT-100V series fi lters incorporate an internal, multi-layer fi lm polymer capacitor
between the input lines for differential-mode noise fi ltering. This telecom/data-
com preferred capacitor provides electrical stability under both AC and DC
current loads. The capacitors insulation resistance tends to improve under the
stresses of heat and voltage. A typical ESR of 6 milli-OHMs @ 500kHz, pro-
vides the necessary low impedance for high frequency input current handling.
