“…As the heat power dissipation of the IGBT is a key parameter for the thermal study, it should be calculated using an electrical model. Several electrical models are presented in the literature [10,[17][18][19][20][21][22]. There are those based on the concept of the equivalent circuit [10,19,20], and those based on the analysis of the different material layers that compose the IGBT structure [18,23].…”

This paper deals with the development of an electro-thermal model of an Insulated Gate Bipolar Transistor (IGBT) with a water-cooled heat pipe cooling system. Firstly, a thermal model of the heat pipe cooling system is proposed. Then, an electro-thermal model of the IGBT is developed to predict the junction temperature variations in transient operation. The thermal model of the IGBT is determined on the base of the thermal-capacitance lumped method. The electrical model of the IGBT is developed by considering the effect of the junction temperature on its static electrical parameters. Finally, the electro-thermal model is considered in a boost converter application. The model predictions show the effectiveness of the heat pipe cooling system for different commutation frequencies. It is proved that the heat pipe cooling system can keep the junction temperature of the IGBT at values allowing safe operation.

“…As a result, while calculating the efficiency of a converter, one should also consider the variation of the losses for each wind speed to clarify the effectiveness of a specific converter for the entire wind speed regime. A calculation of converter efficiency for a given operating condition is performed in [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19] in terms of the total semiconductor power losses.…”

“…Thirdly, physics-based simulation models of semiconductor devices power losses requires implicit integration methods, leading to an increased simulation time. Furthermore, it requires detail knowledge of the dimensions of the devices [14,15]. There have been numerous other efforts for modeling the power losses of converters used in wind turbine systems.…”

An efficiency comparison of power converters is presented for a permanent magnet generator based grid-connected wind energy conversion system. The power converters examined are: the intermediate boost converter (IBC), the intermediate buck-boost converter (IBBC), the back-to-back converter (BBC) and the matrix converter (MC). The aim is to determine which power electronic converter yields the highest efficiency in terms of power losses of the semiconductor devices with the varying wind speeds. In view of this, a furled wind turbine model is developed that generates power for different wind speeds. Afterwards, a relation between the wind speed and power loss is established to evaluate the efficiency of the power electronic converters for discrete wind speeds. The power loss model presented in this paper has taken into account the conduction and switching losses of the semiconductor devices within each converter. Simulation results are presented showing the power loss characteristics with the variation in wind speeds. Finally, with regard to the global efficiency for the power electronic converters of the considered wind speed regime, the IBC is found to be the most favourable choice considering the typical wind conditions encountered by a wind energy conversion system operating at the kWatt level.
