3.3 kV power module enables compact, scalable inverters
Infineon Technologies has launched a flexible IGBT module platform for high-power applications in a new package type for voltages from 3.3kV to 6.5kV.

The symmetrical design of the module reduces stray inductances to significantly improve the switching behaviour in traction and commercial, construction and agricultural vehicles as well as medium-voltage drives.

The XHP 3 package is 140 mm in length, 100 mm in width and 40 mm in height. The first IGBT modules of this new high-power platform feature a half bridge topology with a blocking voltage of 3.3 kV and a nominal current of 450 A. Two different isolation classes have been launched, at 6 kV (FF450R33T3E3) and 10.4 kV (FF450R33T3E3_B5). Ultrasonic welded terminals and aluminum nitride substrates along with an aluminum silicon carbide base plate ensure the highest possible level of reliability and robustness.

The high-power IGBT module is designed for parallel operation in scalable inverter designs. This means system designers can now easily adapt the desired power level by paralleling the required number of XHP 3 modules, with pre-grouped devices featuring a matched set of static and dynamic parameters. Using these grouped modules, de-rating is no longer required when paralleling up to eight XHP 3 devices.

The XHP 3 3.3 kV IGBT modules can be ordered now.
