Claim 14:
15. The system for comprehensively evaluating the reliability of the multi-chip parallel IGBT module according to claim 14, wherein the reliability evaluation module is used to perform a weighted summation on the linear correlation PPMCCC between the gate-emitter voltage in the chip fatigue failure state and the healthy state and the linear correlation PPMCCB between the transmission characteristic curve in the bonding wire shedding failure state and the healthy state to obtain an overall degree of health of the module, and evaluate the reliability of the multi-chip parallel IGBT module from the overall degree of health of the module, wherein the overall degree of health of the module reflects the overall degree of health of the module in terms of a chip health state of the module and a bonding wire health state of the module.
