IGBT-Module integrated Current and Temperature Sense Features based on Sigma-Delta Converter

System integration is one of the market driving issues in power electronics. In this paper the integration of precise shunts into IGBT modules, like it is done in Infineons MIPAQ 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 voltage sense signals is done by sigma-delta converter including a functional isolation barrier by CorelessTransformerTechnology (CLT).
