Phase-split synchronous motors supplied by multiple
three-phase Load Commutated Inverters are of importance in
high power applications. A criticality of such systems is the
possibility that commutations within different stator windings
may overlap. The analysis of the resulting transients is
complicated by the magnetic interference of motor phases among
them and with rotor circuits. In this paper the complete dynamic
model of phase-split synchronous machines is manipulated to
derive a simple analytical and circuital description of
commutation transients, including the case of multiple
simultaneous commutation events. Numeric simulation results
are presented to cross-check the proposed model.
