Condition monitoring of power module using S-parameters, TDR, and TDT

Condition monitoring of power electronics is gaining interest as expends to mission-critical applications. This paper offers a preliminary experimental study the viability using S-parameters and time-domain reflectometry measurements monitor degradation module. To this end, were performed on standard high current module which was artificially aged by cutting wire bonds one one. The demonstrates clear trend in evolution measured parameters, thereby possibility under specific test conditions. opens new condition technology for systems.
