Here is a set of rectifier diodes, three in line for any PMA. Nicely constructed and fairly priced;

What I need to cofnrim is if we need a set of three of these or six for a 3 phase PMA (100 Amps max)? I am told by my technician that we would be needing six, -ve and +ve for each phase, so that's two diodes per phase - although he isn't technically that much qualified.
Secondly, the particular PMA that I am working was 110VAC star configuration, as my battery-pack is 48VDC; I converted it into delta, so another three wires were fetched out from the PMA. Now I intend to put in a manual switch that can switch over from start to delta or vice versa when needed or just to try out the efficiency in both modes, would I still be needing three, or six rectifier diodes? Please illustrate.
Thanks, Usman
