Description
These IRKU/V series of NEW ADD-A-paks use
power thyristors in two circuit configurations. The
semiconductor chips are electrically isolated from
the base plate, allowing common heatsinks and
compact assemblies to be built. They can be
interconnected to form single phase bridges
(IRKU+IRKV) or 6-pulse midpoint connection
bridge. These modules are intended for general
purpose high voltage applications such as high
voltage regulated power supplies, battery charge
and DC motor speed control circuits.
