    Default Multiple rectifiers to drop power supply voltage?

    Hi all,
    Probably a daft question but I was wondering whether anyone can think of a reason (other than global warming) not to use multiple rectifiers in series to drop power supply voltage?

    I've got a lovely 1000VA toroid transformer available for a new power supply but it's putting out 18V more than my drives can handle. As I have a big bag of rectifiers (30A continuous rating) on the shelf I was wondering about wiring 26 of them in series to drop the voltage as each one drops 0.7V. Any advice?
    Cheers,
    Shed

    Remove windings, much more efficient, about 9 turns.
    With a Toriod it is relatively easy.
    There are many previous posts here on the subject.

    Thanks Al,
    Glad someone's shaken off the Chrimbo haze.

    Or if you do not want to cut into the tape and varnish you could add a few windings and connect them in series with but opposite polarity to the existing winding.
