摘　　要：间接矩阵变换器具有无直流滤波电容、控制策略简洁等优点,获得广泛研究;为了提高其供电的电机驱动系统可靠性及满足不间断运行需要,需要驱动系统具有容错运行功能。文中研究了一种间接矩阵变换器逆变级三相四开关供电电励磁同步电动机直接转矩控制(DTC)容错运行技术。分析研究了间接矩阵变换器容错运行的网侧整流级两种控制策略;结合网侧控制策略对逆变级输出电压矢量进行详细推导。仿真和实验结果证明了控制策略的可行性。Indirect matrix converters （IMCs） are widely researched because there are not DC filtering capacities and the control strategy algorithm is simplified for two-step structure. The fault-tolerant operation performance is always needed for the motor drive system supplied by IMC to improve the drive system reliability and satisfy the demand for uninterrupted operation. The direct torque control strategy for electrically excited synchronous motor supplied IMC with three-phase-four-switch inverter step was investigated. Two control strategies for rectification step and the voltage vector were discussed under the condition of fault-tolerant operation. The simulation and experiment results show that the studied control strategies are feasible.
