Abstract
The paper deals with the design issue of the computer simulation models 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 behaviour of the main power circuit
semiconductor components. The topologies, for which the simulation models are created, are
topologies, one of which is commonly used across the automotive industry as the heart of the
traction drive (VSI – Voltage Source Inverter), and its perspective alternative three-level traction
inverter topology T-NPC – T-type Neutral Point Clamped. The simulation models created in the
given simulation tool are thus subjected to the analysis of power parameters, which also include
the calculated power losses of the entire system of semiconductor devices for both topologies
of the traction inverter. Based on the obtained power parameters, the efficiency performance
under various operational conditions of both topologies is evaluated. The presented methodology enables rapid investigation of operational performance enabling fast optimization methods.
Any design of linearized simulation models in the PLECS simulation tool, whose core consists of
semiconductor elements, can be analyzed by the proposed methodology.
