本文首次研究了具有最少功率器件数量的变换器拓扑结构和便于线性开关磁阻电机无脉动力控制的控制实现。器件的最小化降低了成本，紧凑的封装和增强的整体可靠性。考虑到这一点，选择具有3 N/sub sc/+3个设备的拓扑，其中N/sub sc/是线性机器中的扇区数量。传统单相励磁控制的推进力换向转矩脉动大，本文提出的多相励磁控制策略克服了这一问题。此外，所提出的控制策略减少了法向力脉动。提出了一种系统的开关策略设计方法，即单极开关策略、比例积分电流控制器和长线性开关磁阻电机的门控策略。实验相关的建议转换器的安排和控制策略，提出了一个4.8米长的线性开关磁阻电机在实现所述目标。
The converter topology with a minimum number of power devices and control implementations to facilitate the pulsation free force control of linear switched reluctance machines are investigated for the first time in this paper. The minimisation of the devices offers cost reduction, compact packaging and enhanced overall reliability. With that in view, a topology with 3N/sub sc/+3 devices is chosen where N/sub sc/ is the number of sectors in the linear machine. The propulsion force with conventional control of single phase excitation has high commutation torque pulsation and it is overcome with a multiphase excitation strategy proposed in this paper. Further, the proposed control strategy reduces the normal force pulsation. A systematic step by step design procedure of the switching strategy for the converter known as unipolar switching strategy, proportional plus integral current controller and gating control strategy of a long linear switched reluctance machine are presented. Experimental correlation of the proposed converter arrangement and control strategy is presented with a 4.8 m long linear switched reluctance machine in achieving the stated objectives.
