摘　　要：12/8结构开关磁阻发电机(SRG)系统可以实现双通道工作,在一个通道故障时能够实现单通道容错工作模式,以提高电源系统的可靠性。但由于两个通道之间存在强耦合,当系统单通道容错运行时电机性能将受到影响。通过建立12/8结构双通道开关磁阻发电机系统的数学模型,仿真分析不同工作模式下绕组电感和不同通道间绕组互感对电机性能的影响。提出一种新的绕组连接方案,实现了两个通道之间的解耦,以提高系统单通道容错运行时的电机性能。最后实验验证了理论和仿真分析的正确性以及该方案的有效性。Switched reluctance generator （SRG） of 12/8 structure can be implemented for dual-channel working. The single-channel fault tolerance operation mode can be obtained when any channel is failure, namely the power system of the fault tolerance is made for the high reliability. But the out power of single-channel fault tolerant operation mode will be influenced because of the strong coupling between double channels. Based on an analysis of the mathematical model of 12/8 structure of the SRG, windings inductance and mutual inductance on different working status are analyzed and researched by simulation. In this paper, a new windings connection mode is proposed to get the decoupling between double channels and improve its capability of single-channel fault tolerant operation mode. Experiment results validate this theory.
