Electromagnetic Compatibility (EMC)
Filter recommendations for compliance with
CISPR 22/EN 55022, class B
Electromagnetic emission requirements according to EN
55022, class B can be easely achieved by adding an exter-
nal input filter consisting of three additional capacitors and
one common mode ring core choke.
The filter components should be placed as close as possi-
ble to the input of the converter.
