摘　　要：针对传统数值算法求解三相逆变器SHEPWM谐波模型时,难以确定初值,不易收敛等问题,采用改进的ABC-PSO算法求解三相逆变器消谐模型的开关角度,该算法求解出的开关角在同调制度下的线电压、线电流谐波更低,具有更低的总谐波含量。结果表明,在满足基波幅值要求下,输出的电压的5、7、11、13、17、19次及3的倍数次谐波基本为0,消除谐波效果更好,验证了ABC-PSO算法求解SHWPWM方程的可行性。This paper aims to address the difficulty in giving initial values and problem of hard convergence on solving the harmonic model of three-phase inverter SHEPWM by using traditional numerical algorithms.The study uses improved ABC-PSO algorithm to solve the switching angle of the three-phase inverter harmonic elimination model;and the switching angle obtained by this algorithm has lower line voltage,lower line current harmonics and lower total harmonic content under the same modulation system,as which solves the problems of relying on initial values,difficult to converge results,and easy to fall into local minima by traditional algorithms The results show that,under the condition of meeting the requirements of fundamental amplitude,the harmonic eliminations on the 5th,7th,11th,13th,17th,19th,and 3rd multiples of the output voltage are 0 basically,with better effect on harmonic elimination.This verifies the feasibility of the ABC-PSO algorithm in solving SHWPWM equation.
