Abstract：In this paper, a control system based on bi-directional Z-source inverter is discussed for improving dynamic performance of electrical vehicles, and the control scheme for boosting the DC-link voltage is presented. The influence of battery packs' voltage drop on driving performance is analyzed qualitatively under different conditions, such as electric vehicles acceleration. According to the principles of induction motor and vehicles dynamic demand, a topology of bi-directional Z-source inverter is adopted to improve the status of the motor torque reduction due to the large drop of voltage, and improve the output of motor power while electrical vehicles driven at high-speed. The results from the simulations and the experiments of a bi-directional Z-source inverter control system for electrical vehicles verify the feasibility and demonstrated the performance of the proposed control scheme.

Key words： Electrical vehicles bi-directional Z-source inverter dynamic performance Induction motors DC-link voltage
