Description

Dimensioning App IPOSIM for loss and thermal calculation of Infineon IGBT modules IPOSIM-App performs an approximate calculation of switching and conduction losses for IGBTs and free-wheeling diodes in a three phase inverter configuration under the assumption of sinusoidal output currents at inductive loads. With this tool a quick selection of a suitable Infineon IGBT module for an application is possible taking into account its average losses and thermal ratings. DC-link voltage, output and switching frequency, maximum junction temperature, expected case temperature, modulation factor and cos φ can be adapted to specific operation points. The calculation results in diagrams which are showing an estimation of the average power losses at sinusoidal currents versus the RMS phase leg current. The thermal limits of IGBT and diode part of the module (taking into account their thermal resistances and the given values for case and maximum junction temperature) are considered. IPOSIM-App applies an easy to use, fast and at the same time relatively exact method for loss calculation under sinusoidal output conditions. This fulfills the engineer’s need for first estimations on losses and thermal limits of the considered IGBT module. Points to be aware of: - IPOSIM-App device data are based on values given in the respective IGBT module data-sheet. The product data as well as the data used in IPOSIM-App may be subject to changes, improvements or corrections without prior notice. - Calculations are based on linear approximations, e.g. for the device’s forward characteristics, the derivation of switching losses and assumptions e.g. for the recovery energies. Detailed information on the calculations are given on the following pages. - Operating conditions may differ from simulation assumptions in several aspects like level of DC-link voltage, applied gate-voltage and gate-resistor, case and junction temperatures as well as the power circuit stray-inductance. Therefore deviations of parameters and assumptions used for the simulation and the real application may exist. For these reasons Infineon can not take any responsibility or liability for the exactness or validity of the program’s results. The program can not replace a detailed reflection of the customers application with all of its operating conditions.
