Best Answer

it can be used alone

dc welders often just have inductor for filter

sometimes diodes go directly to an inductor

this will lower the current seen by the diodes and the power source

if the diodes go directly to the capacitor the current approaches infinity in the first cycle.

the number of inductors and capacitors in the filter remove more and more ac component

multistage filters are getting rather rare,a power transistor and a heat sink

cost less than capacitors and inductors
