SCALE-2® Plug-and-Play IGBT-Driver

1SP0335 Series - Single Channel Driver with Separate Power Supply Unit Supports Direct Paralleling on a Master-Slave Principle


The 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 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 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 85% compared to conventional solutions, thus significantly increasing reliability and reducing costs. The drivers are equipped with Dynamic Advanced Active Clamping (DA2C), 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.

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.


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.

Electrical insulation and power supply with ISO5125I

The ISO5125I is a single-channel insulated DC/DC converter suitable as a power supply for IGBT drivers up to 6.5kV. It complements the 1SP0335 high-voltage IGBT drivers. Its output power of 5W enables switching frequencies up to 5kHz for 6.5kV/750A IGBTs. On the basis of this concept, the drivers for IGBTs in the voltage range from 3.3kV to 6.5kV 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.
