Abstract : A solid-state commutation system comprising the driving of each pair of 180 deg electrically displaced phases from an even-phased motor with the A.C. current from a dedicated pair of 180 deg electrically displaced phases of an even-phased A.C. generator by routing the A.C. power per phase pair through a plurality of sets of oppositely disposed thyristor pairs which are gated in accordance with a rotor position-sensor connected to the shaft of the motor rotor.
