摘　　要：介绍了四象限变流器瞬态直接电流控制的Matlab建模和仿真方法,建立了四象限变流器的数学模型,并对四象限变流器的牵引工况和再生工况进行了分析。仿真和基于TMS320F2812的实验样机验证了该控制算法不但能有效抑制注入电网的谐波电流,获得稳定的直流输出电压,而且实现了功率因数校正和能量双向流动。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.
