Abstract

A fault current protection system for a traction vehicle propulsion system including a synchronous generator having armature (15) and field windings (12) and power conditioning circuitry (65) connecting the generator armature windings to a traction motor employs a normally charged capacitor (72) which, in response to a fault signal resulting from excess current in the generator armature windings, is electrically switched into parallel with the excitation current source connected to the generator field windings so as to discharge through the generator windings and commutate the excitation current source.
