Abstract  Under the condition of the resonance phenomenon caused by electric locomotive, a scheme for suppressing resonance oscillation by auxiliary converter of electric locomotive based on multiple current tracking control was proposed. The active filter function was applied to the control of auxiliary four quadrant converter. The filter function was obtained by detecting the primary side current of the transformer, generating the compensation current to suppress the voltage resonance at the network. This paper analyzed and designed the parameters of the multiple proportional resonance (M-PR) controller, and quantitatively analyzed the influencing factors of the compensation accuracy. The effectiveness of the proposed method was verified by Matlab/Simulink simulation and RT-LAB experiment.
