A new approach prediction of reliability for power semiconductor devices in cyclic mode based on the numerical analysis of nonuniform temperature fields is proposed. We have compared the failure rates of semiconductor power devices in the real thermal regime under natural convection with statistical data. The necessity to consider the actual unsteady temperature fields to enhance the predicted working resource of the power semiconductor in cyclic mode is shown.
