摘要
建立了多相逆变器的电路模型,并以此为基础,分别建立3相和6相逆变器——异步电机的matlab仿真模型,在不同的开关频率下,分别对三相逆变系统和六相逆变系统进行了仿真。仿真结果表明,在开关频率较低的情况下,多相逆变系统转矩脉动减小,系统效率和功率因数也有所提高。
The mathematical model of multi-phase inverter is set up. A simulation model based on matlab/simulink is proposed. The six-phase inverter can get better performance than three phase inverter even with low switch frequency. The simulation results show that multi-phase inverter has higher power, lower current harmonic and lower power loss.
