| 摘 要： | 电压型逆变器驱动多相电机运行时,虽然降低了转矩脉动,但却在定子绕组中出现了明显的低次谐波电流.抑制多相电机定子谐波电流的方法是串联电抗滤波器,电抗器与多相电机定子绕组电磁结构类似,使在多相电机中不产生旋转磁场的谐波电流在滤波电抗器中产生旋转磁场来抵抗谐波电流.据此提出一种新颖的两电机串联驱动系统,将电抗器换作一台多相电机,使谐波电流在这台电机中产生旋转磁场输出转矩,并且实现对两台电机转矩的独立控制.以双Y移30°六相永磁同步电动机(PMSM)为例,对两电机串联驱动系统建立数学模型并进行了仿真分析,仿真结果验证了串联驱动系统的可行性.

| Abstract: | Multi-phase motors with voltage source inverter(VSI) had smaller torque pulsation than three-phase motors.However,they generally have large low-order stator harmonic currents.Reactance filter was usually used in reducing harmonic current,construction of reactance was resembled the stator of multi-phase motor.By using filter,harmonic currents that do not produce revolving magnetic field in motor will generate revolving field to reduce harmonic currents in the reactance filter.By replacing filter with one mot... |
