Power module achieves 352kW for string inverters

The lead-type of the new family targets applications in photovoltaic string inverters.

In this application it can achieve up to 352 kW and allows a significant increase in output power of about 40 percent compared to last generation PV inverter of 250 kW using EasyPACK 3B.

The module aims to enable a simpler but more powerful inverter design with higher power density and reduced system costs. The device is ideal for 1500 V _DC solar string inverters.

With the introduction of the F3L600R10W4S7F_C22 lead-type, EasyPACK 4B is now the largest package in the Easy family with three DCB substrates.

Nevertheless, it still features a no-baseplate design, 12 mm height, PressFit pins and flexible pinout, and more.

Like the other Easy packages, it offers flexibility in platform-based solutions. The package extends the EasyPACK 3B hold-down concept to ensure low thermal resistance (R _th) and to increase robustness and quality.

Just like the existing Easy family members, the new EasyPACK 4B has optimised stray inductance for reduced design efforts.

The lead-type power module F3L600R10W4S7F_C22 features an advanced 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 optimises the usefulness of the power semiconductor.
