This new VSK series of MAGN-A-PAK modules uses high
voltage power thyristor/thyristor and thyristor/diode in
seven 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
or as AC-switches when modules are connected in
anti-parallel mode. These modules are intended for general
purpose applications such as battery chargers, welders,
motor drives, UPS, etc.
