This new IRK serie of MAGN-A-paks modules uses high
voltage power thyristor/thyristor and thyristor/diode in
seven basic configurations. The semiconductors are
electrically isolated from the metal base, allowing com-
mon 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 appli-
cations such as battery chargers, welders and plating
equipment and where high voltage and high current are
required (motor drives, U.P.S., etc.).

Current-Source Inverters (also known as Sequentially
Commutated Inverters) use Phase Control (as op-
posed to Fast) Thyristors and Diodes.
The advantages of Current Source Inverters lie in their
ease control, absence of large commutation induc-
tances and limited fault currents.
Their simple construction, illustrated by the circuit on
the left, is further enhanced by the use of MAGN-A-
paks which allow the power circuit of an Inverter to be
realised with 6 capacitors and 9 MAGN-A-paks all
mounted on just one heatsink.
The optimal design of Current Source Inverters re-
quires the use of Diodes with blocking voltages greater
than those of the thyristors .
This departure from conventional half-bridge modules
is catered for by MAGN-A-pak range with Thyristors up
to 2000V and Diodes up to 3200V.
