Abstract
Because of the configuration of the single-phase PWM converter in the traction system of EMU, there exists a voltage ripple in the DC-link, which is twice the frequency of the grid. The DC ripple voltage will impact the characteristic of the motor and cause torque and current pulsation, which is called beat phenomenon. In this paper, the origin of the fluctuating DC voltage is analyzed first, and the relations among the torque ripple, the current ripple, and the DC voltage ripple are derived from the analytical model of the traction system. A beat-less control scheme based on the frequency-domain analysis is proposed, and a compensation loop is applied to modify the slip frequency of the motor, thus minimizing the torque and current ripple. The algorithm is verified by simulation.
