IGBT module boost for 352kW solar inverters

New Products |
By Nick Flaherty


Infineon Technologies has developed a single IGBT power module for 1500V inverters that support the largest strings of solar panels at 352kW.

The EasyPACK 4B is now the largest package in the Easy family with three DCB substrates, supporting a 40% higher power level than the previous 250 kW using EasyPACK 3B. The module aims to enable a simpler 1500V inverter design with higher power density and reduced system costs.

The F3L600R10W4S7F_C22 has a no-baseplate design, 12 mm height, PressFit pins and flexible pinout. It also extends the EasyPACK 3B hold-down concept to ensure low thermal resistance (Rth) and to increase robustness and is optimized for stray inductance to reduce design efforts.

The lead-type power module F3L600R10W4S7F_C22 uses a three-level NPC (ANPC) topology that combines the latest generation of 1200 V CoolSiC Schottky diode with the latest 950 V TRENCHSTOP IGBT7 chip technology for up to 600 A.

ANPC is a popular topology in solar string inverters and ensures high efficiency as well as low power losses. This combination of topology and chip optimizes the usefulness of the IGBT devices to make the inverter more cost effective.

The EasyPACK 4B F3L600R10W4S7F_C22 can be ordered now and the Easy 4B package will be available for additional typologies, current ratings and voltage classes.
