DESCRIPTION
This new VS-VSK series of MAGN-A-PAKs uses
high voltage power diodes in two basic configurations. The
semiconductors are electrically isolated from the metal
base, allowing common heatsinks and compact assemblies
to be built. They can be interconnected to form single phase
or three phase bridges and the single diode module can be
used in conjunction with the thyristor modules as a
freewheel diode. These modules are intended for general
purpose applications such as battery chargers, welders and
plating equipment and where high voltage and high current
are required (motor drives, etc.).
