Auto-Qualified IGBT/SiC Driver Family Equipped for Traction Inverters
Check out our PCIM 2022 coverage.
Power Integrations announced its new SCALE EV family of gate-driver boards for Infineon EconoDUAL modules at PCIM. Suitable for original, clone, and silicon-carbide (SiC) variants, the driver targets high-power automotive and traction inverters for EV, hybrid, and fuel-cell vehicles, including buses and trucks as well as construction, mining, and agricultural equipment.
SCALE EV board-level gate drivers incorporate two reinforced gate-drive channels, associated power supplies, and monitoring telemetry. The boards are automotive-qualified and ASIL B certified, enabling implementation of ASIL C traction inverter designs. The first SCALE EV family member to be released is the 2SP0215F2Q0C, designed for the EconoDUAL 900-A, 1200-V IGBT half-bridge module.
The gate drivers are rated at 1200 V for 400- and 800-V systems and support both SiC MOSFETs and silicon IGBTs. The design carries a 5500-meter altitude rating and is optionally available with conformal coating for technical cleanliness requirements.
The boards include a wide range of protection provisions, including active short-circuit; active discharge of connected dc-link capacitor; overvoltage limitation via active gate control; diagnostic functions such as gate monitoring, signal transmission monitoring, and on-chip temperature monitoring; and short-circuit and overcurrent response of less than 1 µs for SiC MOSFETs and less than 3 µs for IGBTs.
