EMC FILTERING AND SPECTRA

FILTERING
The module includes a basic level of fi ltering, suffi cient for many applications. Where lower noise levels are desired, fi lters can easily be added to achieve any required
noise performance.
A DC/DC converter generates noise in two principle forms: that which is radiated from its body and that conducted on its external connections. There are three separate
modes of conducted noise: input differential, output differential and input-output.
This last appears as common mode at the input and the output, and cannot therefore be removed by fi ltering at the input or output alone. The fi rst level of fi ltering is to
connect a capacitor between input and output returns, to reduce this form of noise. It typically contains high harmonics of the switching frequency, which tend to appear
as spikes on surrounding circuits. The voltage rating of this capacitor must match the required isolation voltage. (Due to the great variety in isolation voltage and required
noise performance, this capacitor has not been included within the converter.)
Input ripple is a voltage developed across the internal Input decoupling capacitor. It is therefore measured with a defi ned supply source impedance. Although simple
series inductance will provide fi ltering, on its own it can degrade the stability. A shunt capacitor is therefore recommended across the converter input terminals, so that it
is fed from a low impedance.
If no fi ltering is required, the inductance of long supply wiring could also cause a problem, requiring an input decoupling capacitor for stability. An electrolytic will perform
well in these situations. The input-output fi ltering is performed by the common-mode choke on the primary. This could be placed on the output, but would then degrade
the regulation and produce less benefi t for a given size, cost, and power loss.
Radiated noise is present in magnetic and electrostatic forms. The latter is suppressed by the metal case, which is connected to the output return, typically a zero-volt
point. Thanks to the small size of these units, neither form of noise will be radiated “effi ciently”, so will not normally cause a problem. Any question of this kind usually
better repays attention to conducted signals.
