Working principle, control method of locomotive four quadrant converter and the cause of DC bias in AC side current were introduced. Two common methods to suppress DC bias were discussed. Through theoretical analysis, a control algorithm for DC bias suppression was presented, which optimized the controller design by root locus method. The simulation analysis of software Matlab/Simulink and the test of hardware-in-the-loop simulation platform showed that the control algorithm has good suppression effect and met the design requirements.
