| 摘 要： | 为了将直流母线电压维持在所需的水平,并更好实现整流器的单位功率因数运行,基于预测控制设计实现了三相Vienna整流器的电流控制策略。提出一种改进预测电流控制算法,在每个开关周期的开始,计算整流器平均电压矢量,同时在开关周期结束时消除输入电流矢量分量的跟踪误差,输出矢量再以空间矢量调制SVPWM方法得到调制波,经过驱动电路实现对开关器件MOSFET的控制。基于改进预测电流控制设计了三相Vienna的仿真与实验平台,结果展现了其在动态和稳态下的良好性能。

| Abstract: | In order to maintain the DC bus voltage at the required level and achieve the unit power factor operation of the rectifier,this paper implements the current strategy of the three-phase Vienna rectifier based on the predictive control design.An improved predictive current control algorithm is proposed.At the beginning of each switching cycle,the average voltage vector of the rectifier is calculated,and the tracking error of the input current vector component is eliminated at the end of the switching period.The output vector is modulated by SVPWM(space vector pulse width modulation)method to obtain the modulation wave to realize the control of the switch device(MOSFET)by driving circuit.The simulation and experimental platform is designed based on the proposed predictive current control and the results demonstrate its excellent performance under dynamic and steady state. |
