| Abstract: | According to the needs of the novel linear motor transport system, the structure, the main circuit and the control system of traction converter was designed, and the process of device selection was shown. Indirect vector control method of sliding mode variable structure based on linear motor mathematical model was adopted, which can control the primary current of the linear motor quickly. Normal loading experiment was done. Experiment results showed that the traction converter has a stable, reliable performance which satisfies the demands of the novel linear motor transport system. |
