Abstract

In this paper,thermal properties of the IGBT modules of a 3 MW compact wind turbine generator areanalyzed based on the liquid- cooling system platform of IGBT modules established by a company.Then,according tothe data collected in dynamic experiments,the relationships between the output power of the inverter and time are ex-plored.Moreover,by analyzing the variation characters of the temperature of IGBT modules and the power dissipationwith a combination of experimental data,the temperature of IGBT modules and the heat value varying with time arediscussed for a MW- level wind power converter.Experimental results show that the inverter efficiency of the windturbine generator reaches 98.62%,and that the operation temperature of the IGBT modules ranges from 50 to 56℃.It is thus concluded that the adopted liquid- cooling system has good cooling effect on high- power IGBT modules.

Key words： MW- level wind turbine generator; IGBT module; power dissipation; thermal properties; inverter effi-ciency
