6.1
General
knowledge
of
EMC
EMC
is
the
abbreviation
of
electromagnetic
compatibility,
which
means
the
device
or
system
has
the
ability
to
work
normally
in
the
electromagnetic
environment
and
will
not
generate
any
electromagnetic
interference
to
other
equipments.
EMC
includes
two
subjects:
electromagnetic
interference
and
electromagnetic
anti-jamming.
According
to
the
transmission
mode,
Electromagnetic
interference
can
be
divided
into
two
categories:
conducted
interference
and
radiated
interference.
Conducted
interference
is
the
interference
transmitted
by
conductor.
Therefore,
any
conductors
(such
as
wire,
transmission
line,
inductor,
capacitor
and
so
on)
are
the
transmission
channels
of
the
interference.
Radiated
interference
is
the
interference
transmitted
in
electromagnetic
wave,
and
the
energy
is
inverse
proportional
to
the
square
of
distance.
Three
necessary
conditions
or
essentials
of
electromagnetic
interference
are:
interference
source,
transmission
channel
and
sensitive
receiver.
For
customers,
the
solution
of
EMC
problem
is
mainly
in
transmission
channel
because
of
the
device
attribute
of
disturbance
source
and
receiver
can
not
be
changed.
