| Abstract: | Based on the on-board data of converter in CRH5,the data null drift problem is solved using the theory of probability.A method for calculating the power loss of IGBT module is proposed which is suitable for the whole working condition.The rationality of the thermal network model proposed in this paper is verified through the thermal coupling analysis of the grease layer,the effectiveness is verified by finite element thermal simulation.A thermal resistance calculation method suitable for engineering application in this field is presented. |
