摘　　要：以九开关变换器和非对称六相电机集成车载充电器拓扑结构为研究对象,研究了一种在充电模式下优化的预测直接功率控制策略。该控制策略运用滑模控制方法追踪参考直流电压并给定参考有功功率,采用拉格朗日插值法预测模型功率,计算下一采样周期的有功功率和无功功率,结合矢量脉宽调制(SVPWM)技术实现功率开关控制。在Matlab/Simulink环境中搭建系统模型,仿真结果表明,该方法能够实现单位功率因数下的稳定运行,能够有效降低交流侧电流总谐波失真(THD),改善系统的动态和稳态性能。Based on the topology of integrated on-board charger with nine switch converter and asymmetric six phase motor,an improved predictive direct power control strategy were proposed in charging mode.This control strategy used the sliding mode control method to track the reference DC voltage and gave the reference active power and the Lagrange interpolation method to predict the model power and calculate the active power and reactive power in the next sampling period.The power switching control were realized by combining the vector pulse width modulation(SVPWM)technology.The system model was built in Matlab/Simulink environment,and the simulation results show that the method can achieve stable operation under unit power factor,effectively reduce the total harmonic distortion(THD)of AC side current,and improve the dynamic and steady-state performance of the system.
