Half Wave rectifier is basically a diode which conducts in one direction of current only. With an alternating current (AC) input, a diode cuts off (clips) positive or negative cycle completely.
Whereas, in a clipper circuit, a diode is biased with some voltage. In the case (a) it is positively biased with voltage V. Therefore, in the positive cycle the diode is forward biased and conducts till the voltage reaches V. When the positive voltage crosses V, the diode gets reverse biased and stops conducting ( thus clipping the wave form) until the voltage falls down below voltage V and the diode continues to remains forward biased in the negative cycle until the sine wave once again reaches V. Thus allows the negative cycle completely only clipping off the top section of the waveform
In figure (b) the function is similar.
We can conclude that a half wave rectifier is a clipper circuit with biasing voltage V=0 ( no bias)
