1P 220VAC 50/60 Hz16A EMI POWER LINE FILTER FOR RF SHIELDING ROOM
Power line filter's principle is an impedance adaption network: the
larger the impedance mismatching between line filter input & output
side and power & load side, the more effective the attenuation of
electromagnetic interference (EMI). The specific working principle
is as follows. After AC is rectified by diode, the direction is
single, but the current intensity is still constantly changing.
Generally, this ripple DC is not directly used to power supply. To
make the ripple DC into a smooth waveform, one thing need to be
done, that is filtering. In other words, the task of filters is to
reduce the ripple in the output voltage of the rectifier as much as
possible and transform it into near constant DC.

The commonly-used filter circuits of power line filters have
passive filtering and active filtering. The main forms of passive
filtering are capacitive filtering, inductive filtering and complex
filtering (including inverted L-type, LC filtering, LC π-type
filtering and RC π-type filtering, etc.). The main form of active
filtering is active RC filtering, also known as electronic filters.
The magnitude of the ripple component in DC electricity is
represented by the ripple coefficient S: the larger the value, the
worse the filtering effect of the filter.
