摘　　要：提出不对称空间矢量调制算法,使输出脉冲不再关于载波对称,在维持逆变器开关频率不变的前提下改善系统的谐波性能,提升系统带宽,有效抑制高频电流谐波。为验证该方法,进行了仿真分析,并在实机平台上进行了实验,验证了该方法对永磁同步电机高频谐波电流抑制的有效性。The asymmetric space vector pulse width modulation(ASVPWM)algorithm was proposed,so that the output pulse was no longer symmetrical about the carrier wave.The harmonic performance of the system was improve while maintaining the switching frequency of the switching devices unchanged,the system bandwidth was increased,and the proportional resonant(PR)controller was powerful to suppress high-frequency current harmonics.Simulations and experiments were carried out to validate the method.
