An inductive filter is in fact an LC circuit in which an inductor is connected in series with the capacitor. This arrangement is also known as a low-pass filter. http://www.answers.com/topic/inductive-filter

To know the difference between capacitor and non capacitor rectifiers one must study what is the function of filter part.the filter part consists of capacitors or inductors or combination of both.

the output of a simple diode rectifier is pulsating dc which means it consists of both dc part and ac part. filters are used to remove the ac part from such an output.

capacitor filter means that a capacitor is used for filtering out the ac part.

non capacitor or inductor filter means that an inductor is used for filtering out the ac part.

There is another type called pii filter where both inductor and capacitor are used.

Pii filter is the best kind of filter available

1.More output voltage compared to shunt capacitor filter.

2.Less No of ripples.

1.Higher cost relative to shunt capacitor filter.

2.Larger in size.

The effective resistance of the capacitor reduces the ripple current through the capacitor making it less effective in its function of smoothing the voltage.

But if the capacitor filter is fed by a transformer and diodes, the resistance of the transformer exceeds that of the capacitor.
