The 1SP0335 SCALE™-2 Plug-and-Play
drivers are specifically designed for the reliable and safe driving of 130x140 mm and
190x140 mm IGBT modules with 10.2 kv
isolation voltage and blocking voltages from
3.3 kv to 6.5 kv. They are optimally suited
to high-reliability applications in railway
technology and industry.
The driver concept relies on a master-slave
principle that allows the safe operation of
parallel connected IGBT modules. The master
(1SP0335v or 1SP0335S) can be used as a
stand-alone driver without a slave to drive a
single IGBT module or with up to three
1SP0335D slaves, to drive up to four parallel
connected IGBT modules.
The master is equipped with a fibre-optic
interface and global fault management. In
master-slave configurations, the slaves are
connected to the master by a bus cable
which distributes the common command signal and the secondary-side supply voltages
for the DC/DC converter.
The 1SP0335 drivers are based on Power
Integrations highly integrated SCALE™-2
chipset. Thanks to SCALE™-2 technology, the
new 1SP0335 family comprises highly integrated, high-performance, complete and extremely compact single-channel IGBT drivers.

The SCALE™-2 chipset reduces the component count by 85 % compared to conventional
solutions, thus significantly increasing reliability and reducing costs.
The drivers are equipped with Dynamic
Advanced Active Clamping (DAAC), shortcircuit protection, regulated turn-on gate
driving voltage and supply-voltage monitoring.
Perfectly matched driver versions are available for all mechanically compatible IGBT
modules. The plug-and-play capability of the
driver allows immediate operation after
mounting. The user needs to invest no effort
in designing or adjusting it to a specific
application.

25 v is the nominal output voltage of the ISO5125I power supply. The power supply works with nominal 15 v input voltage.
Maximum switching frequency depends on the IGBT gate charge. See data sheet for the value of a specific driver.

The master (1SP0335v or 1SP0335S) can be used as perfect
standalone driver without a slave to drive IGBT modules without
parallel connection or with up to three 1SP0335D slaves, to drive up
to four parallel-connected IGBT modules. Paralleling is achieved by
simply connecting the master and slaves via the provided
paralleling interfaces X2 and X3, which are identical.

In contrast to the other SCALE™-2 plug-and-play drivers, the drivers
of the 1SP0335 family are modular in the sense that the driver card
and power supply (DC/DC converter) are two separate units. Thanks
to this modular concept, any driver unit that was developed to match
a specific IGBT module can be used for any required
insulation specifications. Only the separate power supply unit
ISO5125I must be chosen to a specific application.
