Power Integrations, the leader in gate-driver technology for medium- and high-voltage inverter applications has announced a new plug-and-play gate driver for use with Infineon’s PrimePACK™3+ and Fuji-equivalent IGBT modules for 2-level and 3-level applications. The SCALE-2™ 2SP0430T2XX gate-driver board suits industrial, traction, UPS and renewable-energy applications, and provides reinforced isolation for 1200 V and 1700 V IGBT modules. Meeting IEC60664-1 and IEC61800-5-1 standards and available in versions that support PD2 and PD3, the 2SP0430T2XX family includes integrated safety features such as UVLO and short-circuit protection plus the new Dynamic Advanced Active Clamping (DAAC). DAAC is especially valuable in protecting photovoltaic inverters (PV) and traction drive applications where unstable voltages can cause DC-link voltages to approach maximum values.

The 2SP0430T2XX gate driver is available in two different versions for 1200 V and 1700 V PrimePACK 3+ IGBT modules supporting different isolation classes: 5000 VAC (50 Hz/1min) and 9150 VAC (50 Hz/1min).

Michael Hornkamp, senior director of marketing for gate-driver products at Power Integrations says, “Our SCALE-2 technology reduces system BOM and improves reliability by including all key protection features and the DC-DC converter within the driver unit. DAAC ensures that units are optimally protected in case of over-current and during short-circuit turn-off. The new 2SP0430T2xx gate driver is a first in the industrial market as it includes a variant for 1700 V PrimePACK IGBT modules that meets PD3 requirements for creepage and clearance distances and is able to operate in 3-level applications with a grounded DC-link. This makes devices very easy to use, reducing engineers’ development challenges and decreasing time-to-market.”
