The Primary function of a rectifier is to convert AC into DC. If we need a DC supply from an AC output we can use a diode bridge as rectifiers.
In many applications or devices like power supplies for radio sets , televisions and computer equipments , a steady constant DC current is required and hence in these applications the output of the rectifier is smoothed by an electronic filter to produce a steady current.
