Description
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 elec-
trically 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 applica-
tions such as battery chargers, welders and plating equip-
ment and where high voltage and high current are required
(motor drives, U.P.S., etc.).

Application Notes
Current Source Inverters
Current-Source Inverters (also known as Sequentially
Commutated Inverters) use Phase Control (as opposed
to Fast) Thyristors and Diodes.
3xIR L
K ...
M
3xIR H
K ...
The advantages of Current Source Inverters lie in their
ease control, absence of large commutation inductances
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 requires
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.
