traction motor drive system and method for selectively isolating fault conditions in a traction motor drive system

摘要

summary “traction motor drive system and method for selectively isolating fault conditions in a traction motor drive system” a traction motor drive system (200) includes a plurality of armatures (104) arranged in parallel between si and a plurality of field circuits (105) arranged in series with each other. the plurality of field circuits (105) are arranged in parallel with the armatures (104). the traction motor drive system (200) also includes a field isolation system (214) including a bypass circuit (215) associated with at least one field circuit (105). field isolation system (214) includes a first field switch (216) arranged in series with the plurality of field circuits (105) and configured to switch between a first bypass circuit terminal (215) and a first terminal at least one field circuit (105). field isolation system (214) includes a second field switch (217) arranged in series with the plurality of field circuits (105) configured to switch between a second bypass circuit terminal (215) and a second field terminal. field of at least one field circuit (105). 1/1
