1SP0335D2S1-5SNA1200G450300

1 sp0335单通道SCALE-2即插即用drivers are designed to safely and reliably drive 130 x 140 mm and 190 x 140 mm IGBT modules with an isolation voltage of 10.2 kV and blocking voltages from 3.3 kV to 6.5 kV. They are optimised for high-reliability applications in the rail sector.

The driver concept uses a master/slave structure 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 up to three slaves (1SP0335D) to drive up to four parallel-connected IGBT modules.

The master is equipped with a fiber-optic interface and global fault management. In master/slave configurations, slaves are connected to the master by a bus cable which distributes the common command signal and the secondary-side supply voltages from the DC/DC converter.

1SP0335 drivers are based on the highly-integrated SCALE-2 chipset. Therefore, the drivers are high-performance, complete and extremely compact. The SCALE-2 chipset also reduces the component count by up to 80% compared to conventional solutions, thus significantly increasing reliability and reducing costs.

1SP0335 drivers are equipped with Dynamic Advanced Active Clamping (DA²C), short-circuit protection, regulated turn-on gate driving voltage and supply-voltage monitoring.

Perfectly-matched drivers are available for all mechanically-compatible IGBT modules. Plug-and-play configuration allows immediate operation after mounting, so the user needs to invest no time and effort in designing or adjusting the driver for a specific application.

Fiber-Optic Interface Options

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

• 1SP0335V equipped with Versatile links
• 1SP0335S equipped with ST links

Power supply and electrical insulation

In contrast to other SCALE-2 plug-and-play drivers, 1SP0335 family drivers are modular, with the driver and power supply (DC/DC converter) presented as two separate units.

Because of this modular concept, any driver that was developed to match a specific IGBT module can be used for any required insulation specifications. Only the separate power supply (ISO5125I) must be chosen for the specific application.

Therefore, drivers for 3.3 kV to 6.5 kV IGBTs can be implemented in 2-level, 3-level and multi-level inverter topologies.

The driver is mounted directly onto the IGBT module using three screws. The power supply (ISO5125I) is separately attached close to the IGBT. For parallel connected drivers, only one power supply is required per switch.
