100 Amps range IGBT modules with integrated sensing and driver electronics

Infineon Technologies has made available its new IGBT modules (Insulated Gate Bipolar Transistor) called MIPAQ base modules in production volumes. The MIPAQ base module integrates an IGBT six-pack and current sense shunts for power equipments such as compact sized inverters in the range of 55 kW.

Measuring 17 mm in height, MIPAQ base module integrates three specifically designed shunts for current measurement. The integrated shunt does all the tasks typically done by external current sensors and also save the PCB and power unit from the heat generated by external shunt.

MIPAQ base modules can handle a nominal current of 75 A, 100 A and 150 A in a 1200 V class for the six-pack configuration with Negative Temperature Co-efficient (NTC) resistor for temperature sensing. The maximum operating junction temperature is +150 °C.

The MIPAQ family is also avaialable in other two types:

MIPAQ sense: Additional feature is, fully digital current measurement with galvanically isolated output signals. The measurement principle uses the Sigma Delta method.

MIPAQ serve: Additional feature is, full set of drivers and temperature measurement on top of the IGBT module enabling plug and play solution for high current drive applications. Inside the module, there is a galvanically isolated driver based on Infineon's Coreless Transformer Technology. The temperature measurement of the base plate inside the module offers an isolated signal as well. There are no optocouplers inside so that longterm stability of the galvanic separation can be achieved.

MIPAQ sense and MIPAQ serve are available in sample quantities now, production volumes of MIPAQ serve is scheduled for Q3 2009, for MIPAQ sense for Q1 2010.
