Infineon Introduces the First 1200V Transfer Moulded IPMs

December 14, 2020 by Gary Elinoff

The new phase inverters integrate a 6-channel 1200 Volt silicon on insulator gate driver with six of the company’s CoolSiC MOSFETs

Members of the CIPOS Maxi IPM IM828 series of intelligent power modules (IPM) provide compact inverter solutions with a wide range of switching speeds for three-phase AC motors as well as for permanent magnet motors used in variable speed drive applications. These new devices can handle as much as 8 kW. 

Silicon Carbide devices are taking the power electronics world by storm, rapidly replacing silicon devices due their well known advantages. The CIPOS MAXI IPM devices complete a yearlong series of IPM launches, covering a wide range of power use cases. We describe one of those related series, the CIPOS Maxi IM818, in another article.

The three series of CIPOS Maxi IPMs are the IM828-XCC/MCC/SCC. They integrate 6-channel 1200 V silicon on insulator (SOI) gate drivers along with six of Infineon’s own CoolSiC MOSFETs. This will reduce BOM count, save space and weight, and improve reliability. The powerful devices are packaged in an isolated DIP moulded housing, and achieves the highest power density in their class.

The gate driver section of the SiC IPM provides built-in dead time, preventing damages from transients. The unit also affords under-voltage lockout (UVLO) at all channels as well as over current shutdown protection and a UL-certified temperature thermistor. To make the unit easier to control, the low side emitter pins can be accessed for phase current monitoring. 

While the current available information describes the IM828-XCC as a series, there only seems to be one device available at this time.


Key Features of the IM828-XCC

Static Parameters

RDS(ON) (typical) is 55mΩ and 70mΩ at junction temperatures of 25℃ and 150℃, respectively

Drain/source leakage current at VDS = 1200V is 1mA, maximum
