Capacitors in metallized polypropylene film for power electronics
AC FILTERING
For the application “filtering in alternated” the capacitor is
excited with a fundamental current that is usually
at 50 or 60 Hz.
Besides the fundamental, there are one or more harmonics
that generate high currents.
The values of these currents must be known and must not
exceed the maximum values declared in the respective
specifications. For this application, MECO capacitors from
the series CML 1 and CML 3 are suitable.
Typical application of these capacitors is in filters at the
output of uninterruptible power supplies (UPS) where there
are several harmonics.
