Power Semiconductor Replacements

Many Brushless Exciter Rectifiers have been in service for more than 20 years.  Over that period of time, many of the original power semiconductors have been obsoleted with the arrival of newer designs and ratings.  It is often difficult to identify an up-to-date replacement device which can successfully replace the older semiconductors.

AC Motor Technologies can identify new devices which will work successfully.

Very often, up-rates are possible which will can physically fit in the same space and provide increased voltage and/or current ratings.
