SCALE-2 Technology

IGBTs from 1200V to 3300V / 800A to 3600A

Direct Paralleling Supported by Master/Slave Drivers

The new 1SP0635 SCALE-2 Plug-and-Play drivers are specifically designed for the reliable and safe driving of 130x140mm and 190x140mm high-voltage and high-power IGBT modules from the 1200V to the 3300V voltage class.

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 (1SP0635V or 1SP0635S) can be used as a stand-alone driver without slave to drive a single IGBT module or it can be used with up to 3  slaves 1SP0635D to drive up to 4 parallel connected IGBT modules.

The master is equipped with a fiber-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 1SP0635 drivers are based on CONCEPT's highly integrated SCALE-2 chipset. Thanks to SCALE-2 technology, the new 1SP0635 family comprises highly integrated, high-performance, complete and extremely compact single-channel IGBT drivers.

The SCALE-2 chipset reduces the component count by 80% compared to conventional solutions, thus significantly increasing reliability and reducing costs.

The drivers are equipped with Dynamic Advanced Active Clamping (DA²C), short-circuit protection, built-in DC/DC converters, 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 invest no effort in designing or adjusting it to a specific application.

Fiber-optic links are used for the electrical insulation of the command and status-feedback signals. Two versions of fiber-optic interfaces are available:

■  1SP0635V is equipped with versatile fiber-optic links
■  1SP0635S is equipped with ST fiber-optic links

For details, check the product documentation.

Note 1: Maximum switching frequency depends on the IGBT gate charge. See data sheet for the value of a specific driver.

Note 2: In product versions 1SP0635x2xx-12, 1SP0635x2xx-17 and 1SP0635x2xx-33, the turn-on and turn-off gate resistors are not assembled in order to provide maximum flexibility. They must be assembled by the user before start of operation. Please refer to the corresponding data sheet for recommended gate resistors. It will be updated with new adaptations regularly.
