It may be rectifier as it converts ac to dc which is smooth.

You are wrong. Rectifiers are used to convert AC to DC (removes thes +ve or -ve part of a given AC waveform). It will not smoothen the output waveform.

Inductors and/or Capacitors are used for filtering purpose.

The o/p of rectifier is consists of some ac components,regulator is used to convert into dc&it avoids the sudden changes in the input at o/p to protect devices.

Filter does the working as a remover of spikes that has been genrerated as ouyput. So filter is the answer as I think so. And if not then please give related suggestion.

Filter is used to reduce the harmonics only but regulators only produces the smooth output.

After filter still some of the positive AC components are available which are removed by regulator. Therefore regulators only produce the smooth output.

Regulator maintains constant DC output.

Shantanu said:   1 decade ago
Regulator is used to give a constant output in-spite of any change in input. Filters are used to bypass the ac component and give a pure DC.

Electronic voltage regulators are found in devices such as computer power supplies where they stabilize the DC voltages used by the processor and other elements.

Firstly transformer step down the voltage, then through rectifier AC changes to DC. After this filter receives the output pf rectifier as input and in the last voltage regulator gives a smooth DC output.
