diode selection + 3 phase supply



Original poster: "Mr Gregory Peters by way of Terry Fritz <twftesla-at-qwest-dot-net>" <s371034-at-student.uq.edu.au>

Hi all,

I would like to make a DC coil by rectifying a 3 phase pole pig.
Firstly, any hints? What effect do the star and delta configurations
have when setting this up? Which is better? I'm wondering which diodes
to use. There appears to be heaps of types such as standard, fast, ultra
fast, etc. What does this mean?

Cheers,
