Design of Piece-wised Linearized Simulation Model of the Traction Inverter Suited for Efficiency Performance Evaluation

This paper deals with the design issue of the computer simulation model of the traction inverter reflecting request on the rapid investigation of the efficiency performance under various operational conditions. According to this, a piece-wised linearized simulation tool PLECS is selected for model development, which considers the relevant loss behavior of the main power circuit components. The selected alternative topology of traction inverter suited for automotive purposes is then subjected to evaluation of the efficiency performance under various operational conditions. The presented methodology enables rapid investigation of operational performance enabling fast optimization methods.
