Simulation and Validation of Power Losses in the Buck-Converter Model included in the SmartElectricDrives Library

In this work a buck converter model included in the simulation software tool the SmartElectricDrives library is verified. The main focus is put on the converter losses. For these purposes a buck converter test bench was designed and set up. The power losses where measured according a defined series of measurements. Conduction and switching losses are investigated in this paper and their impact on the converter behavior is analyzed. As a result of the implemented losses concept the user should be able to parameterize the converter without comprehensive knowledge about transient transistor effects and data sheet availability.
