Power Supply Filters and Regulators – Definition
The filter is a device which is used to eliminate the ripple or fluctuation in DC voltages for achieving a complete smooth DC voltage at output. The working phenomena of regulator is surely outclass because it works when we want to get a desired DC voltage at output.
