| Abstract: | A Matlab simulation method is introduced to realize the transient current control of four quadrant converter and its mathematical mode is established.Analysis the dynamic response,traction condition and regeneration condition are performed.A prototype based on TMS320F2812 is built to verify the performance of the control scheme.The simulation and experimental results show that the harmonic is restrained effectively and power factor correction can be achieved by using the control scheme. |
