Integrated shunts on IGBT modules reduce system costs

Integrated shunt resistors have been added to the EconDual 3 IGBT modules by Infineon Technologies. The integrated shunt resistors are for current monitoring in the AC path. Implementing these devices helps inverter manufacturers to reduce cost, improve performance and simplify the inverter designs, says Infineon. The EconoDual 3 with integrated shunts can be used in a variety of applications, such as general purpose motor drives, uninterruptable power supplies, and solar, as well as  agricultural and commercial vehicles and buses.

Typically new inverter generations aim at reducing cost and increasing power density at high lifetime levels. In addition to improving the electrical performance of IGBTs, diodes, and the interconnection technologies, this integration in an IGBT module enables further cost reduction, says Infineon. The integrated shunts mean that external current sensors are no longer needed. This saves space in the system, reduces material costs and manufacturing efforts, claims Infineon. In addition, the integration results in high current measurement accuracy across a wide temperature range leading to a very precise motor control.

The EconoDUAL 3 shunt module family supports current ranges from 300 to 600A at 1200V. It features Infineon’s trench/fieldstop technology and modules are available with pre-applied thermal interface material (TIM) for lowest thermal resistance and longest lifetime. In addition, the housing with PressFIT pins enables a fast and cost efficient assembly.

The 450 and 600A EconoDUAL 3 modules are already available. An additional variant with 300A is planned to be released in March 2018. All three current classes are supported with an evaluation board which will be launched around mid of 2018.
