I am not exactly sure why it is said it can't be used, I myslef was searching for an answer when I came across this, I have a general idea about this, why I would like to share.
There can be two possible reasons.
1. The inductor produces a back-emf which opposes any change in current, but in the output of a HWR, the decrease in current and a no current state predominates a increase in current, so the inductor will naturally oppose a increase in current, which will mean a low dc voltage is obtained. [i.e. lower than the peak value]
2. The reactance of inductor increases with increase in frequency, the output frequency of a HWR is half that of a FWR. Thus filtering of higher harmonic waves is favoured.

∙ 11y agothe pulsating dc in full wave rectifier as continous but in halfwave discontinous that is square wave like,so that cotinous current cannot achive when half wave used so back emf will produce and the output become more fluctuating than input ac so inductor filter cannot be used in half wave rectifier.

Output voltage of half wave rectifier without capacitor filter is less or more than rectifier with capacitor filter?
less
What is the frequency of ripple components in the output of capacitor filter?
It depends on whether or not it is a half wave or full wave rectifier. For a single phase 60 Hz rectifier, a half wave rectifier will be 60 Hz while a full wave rectifier will be 120 Hz. A three phase full wave rectifier will be 360 Hz.
What happens when one of the diodes is removed from the bridge rectifier?
Nothing will happen to the diode but that rectifier effectively becomes a half-wave rectifier.
What effect does an open diode have on the output voltage of a half wave rectifier and on a full wave rectifier?
An open diode will result in no output from a half wave rectifier, and an open diode will cut the output of a full wave rectifier in half.
What is the purpose of the transformer in the half-wave rectifier circuit?
what is the function of transformer in the half wave rectifier circuit

What is advantage of precision full wave rectifier over precision half wave rectifier?
Either less ripple voltage with the same filter capacitance, or similar ripple voltage with smaller filter capacitances (and thus physically smaller filter capacitors).
What happens when one of the diodes is removed from the bridge rectifier?
Nothing will happen to the diode but that rectifier effectively becomes a half-wave rectifier.

How many diodes are used to make a half wave rectifier?
You use a half-wave rectifier where the system design does not require a full-wave approach. Half wave rectifier output is used for running ac motors.
When a 60 Hz voltage is applied to the input of half wave rectifier what is input freequency?
The relationship of the input frequency and output frequency in a half-wave rectifier is one-to-one.(For full-wave, its one-to-two.)The shape won't be the same, as the rectifier will only pass alternate half-cycles, but the apparent frequency will be the same.
Can clipper act as a half wave rectifier?
A clipper can act as a half wave rectifier but it might be a little hard.
What is the lowest ripple frequency of half wave rectifier?
The ripple frequency of a half-wave rectifier is the same as the input frequency.
Why full wave rectifier is preffered over half wave rectifier?
Efficiency is double in case of full wave rectifier.
How much is the transformer utilisation factor for half wave rectifier?
0.287. I hope this is an academic question and not something you're thinking of using in a circuit; three more diodes are cheaper than the kind of filter you'll need to clean up the output of a half-wave rectifier - AND you throw away half the voltage the transformer is putting out!
