An averaged model of a two-level IGBT inverter with consideration of temperature dependent switching and conduction losses is presented and compared to two other inverter models. In the presented model the influence of the conduction losses on the output voltage waveforms is considered and power balance is guaranteed. The model is not restricted to sinusoidal output currents. Therefore, the model is suitable for calculating the inverter losses in drives at any load and speed down to standstill, either in motor or generator mode. The model is designed such way that typical data sheet information is sufficient for parametrization. In this work emphasize is given to the calculation of losses. A thermal network is used to calculate the junction temperatures. The relations of the proposed model are described and simulation results as well as experimental results are compared and discussed.
