Three Phase Bridge Rectifier
Find out about three phase bridge rectifiers
electric circuit | storage | generalMost wind turbine and hydro
permanent magnet alternators output
three phase alternating current (AC) electricity. In order to get this generated power into a
battery bank, it must first be
rectified into direct current (DC) electricity.
Through our website we have many articles which explain how you can put together a suitable
bridge rectifier ranging from the DIY from scratch
Make a Bridge Rectifier from Diodes to our guide to
Building Your REUK 3 Phase Bridge Rectifier (which describes how to make the final connections for the complete kit we sell in the
REUK Shop).
Three Phase Bridge Rectifiers
However, rather than using individual
diodes or one (or more)
bridge rectifier per phase,
three phase bridge rectifiers are available with five contacts - one for each phase from the
alternator, and the positive and negative outputs.
Pictured above is one such
three phase bridge rectifier rated at
60 Amps and a maximum voltage of
1200V. It has dimensions of 8 x 4 x 2.5cm and was listed for sale on
eBay*.

Note that these are extremely rare on eBay UK, so expect to pay international delivery on your purchase.
Similarly the unit pictured above was also found on eBay and is a
100 Amp rated three phase bridge rectifier manufactured by Toshiba and offered for sale in USA (but with international delivery offered).
The best search to use to find these components is
3 Phase Rectifier (click here to search now - there were over 30 listed at the time this article was written in August 2008).
Note that tou may also find a couple of suitable bridge rectifiers listed as Three Phase Rectifier.
