Answer Posted / rajkumar
In a online ups (not transformerless type) u can see dc
choke is used in ripple reduction at the output of
rectifier.this is in input section of the ups.thn comes the
battery bank, i mean dc bus line. then inverter section.in
the inverter section ac choke is been used with the LC
filter to attenuate high frequency. so the filter is in
resonance mode to get a 50 HZ output.normal the behaviour
of choke is same irrespective of the place where it being
used. but according to funtions it does we can say dc choke
and ac choke.
