N2 - In recent years, SiC power modules are getting more and more attention in the field of Electrical vehicle. In order to aid the design, a design and evaluation method for electrical vehicle SiC module is proposed in this paper. The method considers the impact of the operation condition of electrical vehicle on the efficiency and reliability of SiC Power modules by the accurate modelling and simulation on the motor drive system in Simulink. Moreover, the multiphysics effects in power module, including the coupling relationship among power loss, temperature and mechanical stress fields, are emphasized by the co-simulation between MATLAB and simulation tools COMSOL. By the method, the power loss, temperature and stress distribution of power modules with different chip specification, packaging and layout can be accurately calculated, so that the cost, efficiency, safety and reliability of SiC power modules in the electrical vehicle can be comprehensively evaluated. The proposed evaluation procedure can be regarded as an effective support for the design of power modules, which greatly reduces the design period and cost. In this paper, two 1200V SiC modules with the same packaging and layout but different chips are fully evaluated with the method.
