Abstract
System integration is one of the market driving issues in power electronics. In this paper the integra-
tion of precise shunts into IGBT modules, like it is done in Infineons MIPAQTM family, is compared to
on-IGBT-chip current sense functionality. Temperature measurement via NTC-resistor on DBC-level or
on-IGBT-chip integrated temp-sense-diodes will be treated as well. Further processing of the low volt-
age sense signals is done by sigma-delta converter including a functional isolation barrier by Core-
lessTransformerTechnology (CLT).
