The paper proposes mass transit vehicle AC drive experiment system with feedback-energy, and introduces the structure and running principle of mass transit vehicle AC drive experiment system, and analyzes the composition of the main circuit of the experimen- tal system and the circuit topology of energy storage converter device. Detail working models and circuit principle are introduced at first in this paper. Together with a double closed loop voltage-current control, this is applied for super-capacitor energy storage of relevant construction machinery. Thus make this platform give play to the role of the exploitation of the electric drive and brake control system, drive inverter. To utilize it can develop characteristic of drive and brake control system , simulate train transport running under the circuit and load were booked and the control of driver handle location, at the same time, using detection systems for experimental data to exquisite and process. The system possesses the characteristics of energy-saving, reliable work and high accuracy.
