摘要
The corestructure of inverter DC-link bus film capacitor is too complex, it is more urgent to build the simulation model oncapacitor core loss. Thus, in this paper, the current distribution and the loss distribution of thin film capacitor metal plate were analyzed, and then the mathematical expressions with current distribution and loss distribution were derived on the capacitorplate. On this basis, the concept of equivalent resistivity is put forward, and thelossmodel of equivalent capacitor core was established. By this method, the simulation model with capacitor core was simplified and verified by simulation. At the same time, the structure model of thin film capacitor core was established, and the influence of different core terminals and core shape were analyzed in thefilm capacitor.
