These IRK series of NEW ADD-A-paks use power
diodes in a variety of circuit configurations. The
semiconductor chips are electrically isolated from
the base plate, allowing common heatsinks and
compact assemblies to be built. They can be inter-
connected to form single phase or three phase
bridges. These modules are intended for general
purpose high voltage applications such as battery
chargers, welders and plating equipment
