Hello Samrat,

The UC3854A can be used in a 3 phase application by using a 3 phase (6 diode) bridge rectifier and designing the UC3854A on the DC side of the bridge.

This is similar to a single phase (4 diode) application. Unfortunately I do not have a reference design to share with you.

Regards

John

Hello john
Do you mean to say the waveform reference i shuld give to controller is six pluse rectifier dc voltage? and use one UC3854 controller only and not three?! Please guide me through with any circuit diagram or some external reference.
Thanks
Samrat
