Abstract

To address the issue of bond wires aging in IGBT

a monitoring method based on the crosstalk vdtage peak is proposed. The half bridge circuit composed of IGBT modules is taken as the research object by this method. Based on the switching mode of IGBT modules

the mechanism of bond wire detachment and the process of crosstalk voltage generation are analyzed in detail

and the crosstalk voltage is segmented and modeled. The impact of wire detachment on the formation of crosstalk voltage at various stages has been derived

and real-time monitoring of the health status of IGBT module bond wires is achieved by measuring the peak value of crosstalk voltage. The simulation and experimental results have verified the feasibility and accuracy of this method.
