Using virtual prototyping (VP) design tool to evaluate power converter electro-thermal performance can help designers to validate prototype in a quick way. However, different system time-scale requires efficient electro-thermal simulation techniques. Thus, an approach by using average power losses of one switching cycle is presented in the paper to decouple electrical and thermal simulation so as...
Virtual prototyping (VP) is very important for power electronics systems design. A virtual prototyping design tool based on different modelling technology and model order reduction is proposed in the paper. In order to combine circuit electromagnetic model with power semiconductor device models, a SiC-JFET behavioural model is presented and implemented in the design tool. A half bridge circuit using...
A real-time prognostic tool to predict life-time of IGBT power modules in a metro application is presented. Applying conventional life models (e.g. Coffin-Manson) for real applications is infeasible because these models are only applicable to cyclic data. Use of off-line rainflow algorithm is common solution but cannot be applied in real-time in its original form. This paper presents on-line life-estimation...
