FILTER CIRCUITS

It is always better to use a shunt capacitor (C) with series inductor (L) to form an LC Filter. As the name suggests, a capacitor is used as the filter and this high value capacitor is shunted or placed across the load impedance. This capacitor, when placed across a rectifier gets charged and stores the charged energy during the conduction period.
