The 1SP0335 single-channel SCALE-2 Plug-and-Play 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 CONCEPT's 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

For details, please check the product documentation. 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. go to ISO5125I power supply for 1SP0335 drivers (Insert link)

Power Integrations offers highly integrated IGBT drivers. Based on decades of experience, ASICs have been developed for the driver and monitoring functions, which together with the inductive transformers form the core of the drivers. Extensive application design support is offered.

Highly integrated driver components: cheaper than discrete in-house development

MOSFETs and IGBTs are convenient to drive with low power, unlike bipolar power semiconductors. However, high gate capacitances must be recharged and, in the case of stacked IGBTs for HVDC (high-voltage DC transmission), large potential differences must also be bridged. In addition, there are protection functions for the power semiconductors and a negative bias voltage for IGBTs to be blocked so that they cannot switch through and fail as a result of transients in bridge circuits.

In view of the high voltages, some know-how is required here. For example, special regulations on insulation clearances, clearances and creepage distances, and partial discharge resistance must be observed, and these must also be checked with expensive measuring equipment. Likewise, the degradation of the board substrate and the migration of metal ions in it must be taken into account, which can otherwise lead to premature short circuits and total failures.

Instead of launching costly in-house developments, it makes sense here to use proven, safe driver modules designed using in-house developed, monolithic highly integrated semiconductor components as well as proprietary planar transformers, such as those offered by Power Integrations under the name SCALE (which stands for Scaleable, Compact, All-purpose, Low-cost and Easy-to-use). Power Integrations, previously CONCEPT, has been developing IGBT driver solutions for over 30 years and therefore has unrivaled experience with this topic.

The SCALE devices are driven with standard logic levels from 3.3 to 15 V and are very economical in the IGBT field: they are cheaper and more reliable than conventional discrete circuit designs, especially when it comes to driving high-voltage IGBTs. Thus HY-LINE Power Components offers you everything around inverters and high performance DC/DC converters from one source.

Power Integrations offers both general modules, the SCALE Driver Cores, and modules adapted to specific IGBT modules, the SCALE Plug-and-Play Drivers. In addition, there are the monolithically integrated SCALE iDriver chips.

Our products fit into the most diverse fields of application. If there is no suitable product for you, please ask us, we will also be able to offer you an ideal solution for your field of application.
