# 3-phase 200Vac rectifier output voltage

I was studying about 3-phase power supplies. After going through several searches, i found this formula of three phase bridge rectifier's output voltage:

Vdc = ( 3 x sqrt(2)/pi ) x Vrms

Vdc = 1.35 x Vrms

So, in the figure given below, should I take 200 Vac as a phase voltage or line voltage. Is it Rms or peak voltage. what should i put in the equation.

• Since no Neutral is used. It seems to be delta wiring, thus delta voltage Mar 8, 2018 at 15:31
