Fig. 4.8(a) presents the power circuit of the multiphase half-wave or the so-called common-point rectifier. As can be seen for every input ac source there is one diode. Moreover,
Fig. 4.8(b) shows the waveforms of the rectifier for pure dc load current of

value (i.e., ωL
≫
R). As can be seen from
Fig. 4.8(b) the diode conduction sequence is D
1, D

3. At any instant the diode with the highest positive anode voltage is conducting and at the same time is forcing the rest to be reverse biased. If the rectifier is supplied by k number of phases, then the output voltage for each operation cycle consists ...
