Vishay introduced four new IGBT power modules designed specifically for string solar inverters and medium-power uninterruptible power supplies (UPS).
Combining Ultrafast Trench IGBTs, high-efficiency HEXFRED and FRED Pt diode technologies, and thermistors for easy thermal management in single packages featuring pressfit technology, they offer complete integrated solutions for inverters based on 3-level neutral point clamp (NPC) topologies and interleaved multiple-channel MPPT (maximum power point tracking) boost converters.
For 3-level NPC topologies, the VS-ENQ030L120S provides a collector-to-emitter breakdown voltage of 1200 V and a collector current rating of 30 A. Designed for 3-level inverter stages, the VS-ETF075Y60U and VS-ETF150Y65U offer designers a choice of 75 A and 150 A collector current ratings and 600 V and 650 V collector-to-emitter breakdown voltages, respectively, and provide high-temperature performance to +175°C.
Optimised for double boost converters, the 15 A VS-ETL015Y120H features a collector-to-emitter breakdown voltage of 1200 V, high-efficiency silicon boost diodes, integrated 62 A bypass diodes, and panel short-circuit, full-current reverse polarity protection diodes.
All devices offer a modular and scalable design to fit higher power level applications. Offered in the EMIPAK-1B (VS-ENQ030L120S) and EMIPAK-2B (VS-ETF075Y60U, VS-ETF150Y65U and VS-ETL015Y120H) packages, the modules’ solderless pressfit technology allows for easy PCB mounting, while an exposed DBC substrate promises low thermal resistance.
The devices provide low internal inductance and switching losses while offering operating frequencies up to 20 kHz. Their optimised layout helps to minimise stray parameters for better EMI performance. They are RoHS compliant and custom solutions can be tailored to meet specific application requirements.
