415 3phase AC to DC


Using a 3phase full wave diode array to convert 415VAC 3phase to a single DC output.   What is the maths to convert to the max peak voltage?

Is it  415 *  SQRT(2) = 415* 1.414?

Perhaps best to link to an actual circuit you want to apply this to, as there are a few ways to refer to 3-ph full wave rectification.  Eg. 3-phase (no neutral) with diode bridge is perhaps most common.  Suggest you go through a decent reference like "Rectifier Applications Handbook" by On-Semi.

Yes, peak will be rms * sqrt 2 for the usual 6 diode arrangement.
