The diode bridge can be generalized to rectify polyphase ac inputs. for example, for a three-phase ac input, a half-wave rectifier consists of three diodes, but a full-wave bridge rectifier вђ¦ three-phase rectifier the purpose of this circuit is to input a three-phase ac signal , retain its positive portion and flip its negative part, filter it and produce a dc signal .

A single phase half wave diode rectifier gives (under ideal conditions) an average dc output voltage m odc v v пђ = and single phase full wave diode rectifier gives (under ideal conditions) an average dc output voltage 2 m odc v v пђ = , where vm is maximum value of the available ac supply voltage. thus we note that we can not control (we can not vary) the dc output voltage or the average dc operation and analysis of three phase uncontrolled rectifier. instructional objectives on completion the student will be able to вђў draw the conduction table and waveforms of a three phase half wave вђ¦

The input power supply may be either a single-phase or a multi-phase supply with the simplest of all the rectifier circuits being that of the half wave rectifier. the power diode in a half wave rectifier circuit passes just one half of each complete sine wave of the ac вђ¦.

The average (dc) output voltage is higher than for half wave, the output of the full wave rectifier has much less ripple than that of the half wave rectifier producing a smoother output waveform. in a full wave rectifier circuit two diodes are now used, one for each half of the cycle..
