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