| Abstract: | A design of the DC traction power supply of the urban rail transit is proposed based on three-phase voltage source PWM rectifier.The current control based on the synchronous rotating frame and the space vector PWM are used for the rectifier to achieve the current decoupling and high voltage utilization ratio.The experimental results show that the con-trol system reaches the design requirements and has fast dynamic response,excellent steady-state performance, unity power factor and low harmonic content. |
