1SP0335 Series

Single Channel SCALE-2 Plug-and-Play Driver Supports Direct Paralleling

SCALE-2 Technology

IGBTs from 3300V to 6500V / 200A to 900A

Direct Paralleling Supported by Master/Slave Drivers

Short Description

The new 1SP0335 SCALE-2 Plug-and-Play drivers are specifically designed for the reliable and safe driving of 130x140mm and 190x140mm IGBT modules with 10.2kV isolation voltage and blocking voltages from 3.3kV to 6.5kV.

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 slave to drive a single IGBT module or it can be used with 1 to 2 slaves 1SP0335D to drive up to 3 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 1SP0335 drivers are based on CONCEPT's 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 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, 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 Interface Options

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

■ 1SP0335V is equipped with versatile fiber-optic links
■ 1SP0335S is equipped with ST fiber-optic links

Power supply and electrical insulation

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 or adjusted to a specific application.

On the basis of this concept, the drivers for IGBTs in the voltage range from 3.3 to 6.5 kV can be implemented in 2-level, 3-level and multi-level inverter topologies.

The driver unit is mounted directly onto the IGBT module by means of three screws. The power supply unit ISO5125I is designed as a separate module attached close to the IGBT. For parallel connected drivers, only one power supply is needed per switch.
