Abstract
Wind energy is one of the most promising renewable sources to generate electricity worldwide and its market share has been growing continuously. In this scenario, the installation of wind turbines with increasing capacities also increases the heat losses, affecting directly the performance of the power converters. The purpose of this work is to investigate the heat losses and the temperature distribution of IGBT modules applied in a water-cooled power converter of 5 MW wind turbine. A time-based physical model considering a mixed equivalent thermal circuit is proposed. Real devices data is taken into account as input variable. Preliminary results confirm the suitability of the suggested cooling method, even for a low flow rate.
