Prognostic Reliability Analysis of Power Electronics Modules
This paper describes a physics-of-failure (PoF) based prognostic method for power electronics modules (PEMs). Differing from the traditional reliability prediction methods, this approach allows the reliability performance of PEMs to be assessed in real time. Four techniques have been used to develop this method, they are: (1) Compact electro-thermal model (2) Rainflow counting algorithm (3) Com...

Power electronics uses semiconductor technology to convert and control electrical power. Demands for efficient energy management, conversion and conservation, and the increasing take-up of electronics in transport sys...
متن کاملAdvanced packaging yields higher performance and reliability in power electronics
Power density of power electronics will continue to grow. It is always supported by progress in power semiconductors. Further significant loss reduction of IGBT and diodes becomes possible if power circuit design improves with respect to electro-dynamic performance. Efforts to improve cooling for better power dissipation out of smaller volumes appear to be disadvantageous in comparison to incre...
متن کاملOptimizing the Reliability of Power Electronics Module Isolation Substrates
1. Abstract Optimal design of a power electronics module isolation substrate is assessed using a combination of finite element structural mechanics analysis and response surface optimisation technique. Primary failure modes in power electronics modules include the loss of structural integrity in the ceramic substrate materials due to stresses induced through thermal cycling. Analysis of the inf...
متن کاملReliability of Cu nanoparticle joint for high temperature power electronics
Power cycle reliability of Cu nanoparticle joint has been studied for high temperature operation of power devices. Al2O3 heater chips and Cu–65 wt% Mo baseplates were joined by Cu nanoparticles and Sn–0.7Cu and power cycle tests of 65/200 C and 65/250 C were carried out on the joints. The Cu nanoparticles were prepared by reducing Cu carbonate in ethylene glycol with dodecanoic acid + dodecyl a...
