Hi,
I need a 3 phase bridge rectifier that can handle around 15A / Phase.
The limit for fairly inexpensive ones seems to be 35A, higher than this and the price is just not viable for the product.
I know paralleling diodes is not a good idea since one diode will usually take most of the current.
My idea is to use 3 35A single phase rectifiers, with each rectifier having it's AC inputs tied together, which works out cheaper even than the one 3 phase 35A unit.
They will of course be bolted to the chassis of the machine, and have thermal grease, and the duty cycle is less than 10%
Can anyone think of a reason why this is a bad idea?
Regards
Bob.
