FIELD: transport.
SUBSTANCE: invention relates to hybrid propulsion systems. In compliance with the first version, proposed system comprises primary DC link, motor, local DC link, power accumulation module, diode/diodes made to transfer power generated by motor to resistor system of dynamic braking. In compliance with the third version, is comprises hybrid propulsion drive that incorporates primary DC link, motor, power accumulation module, switch and DC-to-DC converter. Note that the latter receivers motor power via diode. Proposed vehicle comprises hybrid propulsion drive incorporating primary DC link, motor, electric appliances, local DC link, electrical circuit to allow electric appliances receiving electric power from onboard power generation system. Note also that electric circuit comprises diode/diodes. Proposed method consists in that power accumulation module is electrically connected with motor via switch when motor runs at first rpm. Motor is connected with power accumulation module via voltage converter when motor runs at second rpm. Mind that second rpm exceeds first rpm.
EFFECT: higher efficiency.
