International audience; This paper deals with online measurement of degradation sensitive electrical parameters leading to a healthmonitoring approach for power module. The on-state resistance RDSON is a key aging indicator of silicon carbideMOSFETs. It can provide information on both chip and packaging degradation allowing more reliable powerelectronic converter. This on-state resistance can be determined using both the on-state current and voltage of thepower semiconductor. This paper focuses on an on-state voltage measurement circuit for high power modules (upto 3.3 kV, 500A SiC module). A power module switching oscillation model is used to design and fine tune theproposed solution. Finally, the proposed circuit is successfully tested on a double pulse test for various modulebase plate temperatures and compared to data obtained with a static curve tracer Keysight B1505.
