Abstract

Purpose The main purpose of this paper is to propose a quasi-impedance source (QIS) converter fed switched reluctance motor (SRM) drive. The proposed converter topology is configured for DC link capacitance minimization and power factor (PF) correction. Design/methodology/approach A QIS converter is used as a front end converter to reduce the bulk capacitance requirement during current commutation and to decline the power ripple. To improve the PF with reduced total harmonic distortion at the input current, the PF current control loop is merged with the QIS converter control loop. Findings The overall SRM drive speed is regulated over a wide range by controlling the DC link voltage. The voltage regulation can be achieved by pulse width modulation of the QIS converter. Hence, the overall system efficiency has been improved by operating the proposed converter at a low switching frequency. Moreover, the proposed QIS converter uses an advanced repetitive controller to achieve voltage regulation and fewer ripples in torque. Originality/value The steady state and dynamic analyzes have been performed on the proposed drive topology. The performance of the proposed topology has been simulated through MATLAB/Simulink environment. A hardware prototype with a processor of Xilinx SPARTAN 6 field-programmable gate array has been used to validate the experimental response with the simulation results.

利用前端变换器提高开关磁阻电机驱动性能

目的本文的主要目的是提出一种准阻抗源（QIS）转换器供电的开关磁阻电机（SRM）驱动器。所提出的转换器拓扑结构被配置用于DC链路电容最小化和功率因数（PF）校正。设计/方法/方法QIS转换器用作前端转换器，以降低电流换向期间的大容量需求并降低功率纹波。为了在降低输入电流的总谐波失真的情况下改善PF，将PF电流控制回路与QIS转换器控制回路合并。发现通过控制直流链路电压，可以在宽范围内调节SRM驱动的整体速度。电压调节可以通过QIS转换器的脉冲宽度调制来实现。因此，通过在低开关频率下操作所提出的转换器，提高了整个系统的效率。此外，所提出的QIS转换器使用先进的重复控制器来实现电压调节和较少的转矩波动。独创性/价值对所提出的驱动拓扑结构进行了稳态和动态分析。通过MATLAB/Simulink环境对所提出的拓扑结构的性能进行了仿真。利用Xilinx SPARTAN 6现场可编程门阵列处理器的硬件原型，用仿真结果验证了实验响应。
