In capacitors the voltage of the residual
surge (1300V) is higher than that of the
above example. The wave height is
almost the same as the original.
Conventional EMI filters do not work for
wide-pulse noise because capacitors
are saturated. In this example, the
residual 1200V surge can cause the
system to breakdown.
Bypassing the high voltage to the
ground, voltage can be suppressed.
