Abstract
A system for determining rotor position of an n-phase alternator driven by an inverter uses as inputs the stator terminal voltages of the alternator with respect to the negative power bus, which are already also provided as inputs to the inverter, and provides as outputs simulated rotor positions states. The simulated rotor position states are provided to one or more inverter controllers which, in turn, provide firing signals to one or more corresponding inverters which are used to crank an engine, e.g., an internal combustion engine of a diesel electric locomotive.
