AB - The method of calculation to determine the mode of IGBT module operation for the two-level voltage inverter is proposed. IGBT module does not have a metal base plate in the calculation assumed. The intensity of the cooling module takes into account the thermal impedance of the heat sink.<br />The maximum permissible switching frequency of IGBT at limited ambient temperature, thermal resistance of the heat sink, load current of the inverter and the maximum permissible IGBT chip temperature are given.<br />Calculation formulae for determination of the maximum and minimum IGBT chips temperatures under cyclic loading are proposed for use.<br />On the basis of experimental research done by SEMIKRON firm the formulae for determination of the number of cycles to failure IGBT4 modules, which are dependent on the temperature differences and the mean temperature of the IGBT chip in cycle, are proposed
