Aim to 4-quadrant PWM rectifier of CRH3 high-speed EMUs traction system, a predictive current control method based 4-quadrant PWM rectifier simulation model with Matlab/Simulink was established based on principle and control scheme analysis. The results indicated that this model could output steady DC-link voltage and achieve close to unity power factor and a small quantity THD.
