8- Electromagnetic Interference
Electromagnetic interference requirements according to EN55022 class A and class B can be easily achieved as indicated in
the following table :
Electromagnetic interference requirements according to
EN55022 class A can be easily achieved by adding an
external
common
mode
noise
capacitance
(C
C
= 10nF/rated voltage depending on isolation
requirement) and an input capacitance (C
I Value explained
in previous table). This common mode noise capacitance
C
should be layed-out as close as possible from the DC/
DC converter.
8-1 Module Compliance with EN55022 class A Standard
8-2 Module Compliance with EN 55022 Class B Standard
Electromagnetic interference requirements according to
EN55022 class B can be easily achieved by adding an
external input filter consisting of 4 capacitances, a common
mode
choke,
a
differential
mode
inductance
and the common mode noise capacitance (C
C
= 10nF/rated
voltage depending on isolation requirement).
Please consult EN55022 Class B EMI Filter design note for
further details.

* Note : Value of common mode noise capacitance depends on isolation requirements (typically 10nF/1500V or 10nF/3000V ). In case of dielectric strengh test in AC mode,
adapt the capacitance value in order to be compatible with maximum admissible leakage current.
