Abstract
This paper deals with a simulative approach for
investigating the impact of inverter pulse inhibition during
field weakening operation of permanent magnet synchronous
machines and asynchronous induction machines. The modelling
and simulation language Modelica is used to design models for
the vehicle, the electric machine and the inverter in different
abstraction levels. It is shown that when using a permanent
magnet synchronous machine, a sudden breakdown of the field
weakening current causes induction of high voltages in the stator
windings. Hence, the electric system of the vehicle has to be
protected against the resulting high currents. Furthermore precautions
have to be taken to avoid dangerous driving conditions
because of high braking torques in an inverter fault operation
mode. In the case of the asynchronous induction machine an
inverter pulse inhibition poses no big problem, neither for the
electric system of the vehicle, nor the driver.
