Major part of the filtering is done by the first capacitor in a CLC filter because _________(a) The capacitor offers a very low reactance to the ripple frequency(b) The capacitor offers a very high reactance to the ripple frequency(c) The inductor offers a very low reactance to the ripple frequency(d) The inductor offers a very high reactance to the ripple frequencyI have been asked this question by my college professor while I was bunking the class.Query is from CLC Filter in portion Application of Diodes of Electronic Devices & Circuits

Answer»

Correct option is (a) The CAPACITOR offers a very low reactance to the ripple FREQUENCY

The best I can EXPLAIN: The CLC filters are used when high voltage and low ripple frequency is needed than L SECTION filters. The capacitor in a CLC filter offers very low reactance to the ripple frequency. So, maximum of the filtering is done by the first capacitor across the L section part.
