This paper introduces a newly developed Power Electronic Inverter library in Modelica. The library has different levels of complexity to approximate the power losses in the power inverter. In addition, it provides two different modelling domains (ABC and DQ). The library utilizes a multi-level approach with increasing model complexity, each model is interchangeable in the system including power inverter, controller and machine. There are two attributes which are implemented into this library. First, the model calculates the electric behaviour of the power semiconductors, i.e. IGBTs, MOSFETs and diodes including the thermal effects. This can be fully parameterized based on the characteristic curves and parameters specified in the manufacturer's datasheet. Secondly, the analytical approach of power losses approximation based on the datasheet. It is interchangeable between two reference frames (ABC and DQ). The model is then validated with PLECS simulation to confirm the accuracy.
