FIELD: transportation.
SUBSTANCE: invention relates to the vehicles electrical traction systems. Electric make-up plant of vehicle comprises control system, constant voltage source, three-phase voltage inverter, assembled on transistor half-bridges and condensers, traction electric motor of alternating current, parallel accumulator of electric energy and matching electric converter. DC voltage source consists of two identical sections connected in series and contains output of middle - zero point. Three-phase voltage inverter capacitors are connected in parallel to each DC voltage source section, wherein common point of connection of capacitors and sections of constant voltage source form first output phase of three-phase voltage inverter, and outputs of two transistor half-bridges form second and third output phases. Matching electric converter of parallel accumulator of electric energy consists of throttle and two additional transistors with antiparallel connected diodes.
EFFECT: technical result consists in improvement of reliability and improvement of power characteristics of electric drive of propulsion complex.
