3 Phase Bridge Rectifier Circuit. Three phase bridge rectifier diode rectifiers. The advantage of 3 phase full wave rectifiers is that the output voltage is regulated and do not falls to zero.
Three phase bridge rectifier above diagram shows three phase full wave uncontrolled bridge rectifier consisting of 6 diodes also commonly called as a 6 pulse rectifier. It is also called 6 diode half wave rectifier. The single phase bridge rectifier consists of four diodes for converting ac into dc whereas a three phase rectifier uses six diodes as shown in the figure.
It is also called 6 diode half wave rectifier.
Polyphase systems with more than three phases are easily accommodated into a bridge rectifier scheme. In three phase full wave rectifier six diodes are used. In this each diode conducts for 1 6 th part of the ac cycle. High voltage direct current transmission.
