The speed at which switched reluctance motors (SRMs) make transitions from chopping control to single pulse operation (i.e., low-speed to high-speed operation) is unsatisfactory for realizing optimum performance at all operational regimes. In this paper, we improve the operational performance of SRMs using the current hysteresis control method, which is able to maintain a generally flat current waveform. At high speeds, the current-chopping capability is lost because of the development of the back-EMF. Therefore, SRMs operate in single pulse mode. By using the zero-current switching and zero-voltage switching techniques, the stress of power switches can be reduced in the chopping mode. When the commutation changes from one phase winding to another phase winding, the current can become zero rapidly in this period because a negative DC-source voltage is produced several times in the phase winding. In this paper, we compare the performance based on the energy-efficient C-dump converter topology and the proposed resonant C-dump converter topology. We present simulation and experimental results to verify the effectiveness of the proposed circuit.

建议的谐振 C-dump 转换器在开关磁阻电机驱动中的性能

开关磁阻电机 (SRM) 从斩波控制过渡到单脉冲操作（即低速到高速操作）的速度对于在所有操作状态下实现最佳性能都不能令人满意。在本文中，我们使用电流滞后控制方法提高了 SRM 的运行性能，该方法能够保持大致平坦的电流波形。在高速下，由于反电动势的发展，电流斩波能力会丧失。因此，SRM 在单脉冲模式下运行。通过使用零电流开关和零电压开关技术，可以降低斩波模式下功率开关的应力。当换相从一相绕组变为另一相绕组时，在此期间电流会迅速变为零，因为在相绕组中多次产生负直流电源电压。在本文中，我们比较了基于节能 C-dump 转换器拓扑结构和所提出的谐振 C-dump 转换器拓扑结构的性能。我们提出了仿真和实验结果来验证所提出的电路的有效性。
