Description
These series of INT-A-paks modules uses high voltage
power thyristors/ diodes 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.
These modules are intended for general purpose applica-
tions such as battery chargers, welders and plating
equipment 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 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 INT-A-paks
which allow the power circuit of an Inverter to be
realised with 6 capacitors and 9 INT-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 INT-A-pak range with Thyristors up to
2000V and Diodes up to 3200V.
