The DC-link voltage contains a ripple component with a twice power line frequency while the major traction system in high-speed EMU is operating. And this leads to beat phenomenon. In this paper, the model following the traction system is established and the origin of beat phenomenon effect is analyzed in detail. The causes of the influence on torque and current by the secondary voltage ripple are explored through the analysis of working mechanism while the system is operating. Then, a beatless control scheme based on the frequency modulation and vector control is discussed in detail to eliminate voltage ripple in traction control. The hardware secondary resonant circuit will be canceled to realize the lightweight and low cost. Simulation and experimental results on MATLAB/Simulink confirm the effectiveness and validity of the adopted scheme.
