SCALE-2 'plug-and-play' gate driver targets railway applications

Power Integrations has announced a SCALE-2 gate driver for 130 x 140 mm single IGBT high-power (IHM) modules, commonly used in railway and other long-life applications

Comprising the 1SP0630V2M1R main driver, 1SP0635D2S1R peripheral driver and ISO6125R-33 power supply, the SCALE-2 plug-and-play gate drivers are intended to streamline system development and installation. These gate drivers are particularly beneficial in systems requiring parallel modules for additional power, providing simplicity and flexibility in both electrical and mechanical design.

The SCALE-2 gate drivers match the footprint of the smaller IHM single-channel IGBT-module formats with 1200 A to 1400 A output current and 3300 V IGBT blocking voltage. 1SP063xxxx1R gate drivers are available to suit IHM modules from all major manufacturers, including Infineon, Mitsubishi, Hitachi and ABB.

SCALE-2 technology uses an ASIC chipset to reduce component count and size, and will enable designers to optimise dynamic switching performance, accuracy and functionality and include advanced active clamping circuitry to protect the IGBT.

The 1SP063xxxx1R gate drivers meet IEC 61373 specifications for shock and vibration and IEC 60068-2-xx environmental requirements. Units are also EMC-qualified according to EN 50121-3-2 and IEC 6100-4-x. With standard conformal coating, the new gate drivers can also undergo burn-in on request for added reliability. Improved connectors increase interconnection security and facilitate fast release without tooling. Fiber-optic interfaces are provided.

1SP063xxxx1R gate drivers include protection features such as Dynamic Advanced Active Clamping, short-circuit and under-voltage lock-out. Failure status output is also provided.
