| 摘 要： | 为实现航空多相永磁发电机在宽转速范围下的稳压并提高电能质量的目标,采用了一种改进的SVPWM过调制策略。该方法无需根据调制比的数值去分别计算角度,而是将所有的区域进行统一化处理,免去了复杂的计算,易于实现。仿真模型证明了其可行性,为该过调制策略与单电流调节器弱磁控制系统相结合对航空电源系统进行控制打下了基础。

| Abstract: | In order to achieve the goal of stabilizing voltage and improving power quality of aviation multiphase permanent magnet generator with wide rotation speed range,an improved SVPWM over-modulation strategy was adopted.This method does not need to calculate angles separately according to the value of modulation ratio,but unifies all the regions,which avoids complex calculation and was easy to implement.Its feasibility was proved in simulation model,which lays a foundation for the combination of the over-modulation strategy and the single current regulator flux weakening control system to control the aviation power system. |
