摘　　要：为克服逆变器非线性因素造成的不利影响,本文分析了电压源型逆变器的非线性因素以及其对输出相电压的影响,并结合矢量控制算法,采用了一种基于q轴电流误差的在线补偿方法,该补偿方法不需要外加硬件电路且无需已知逆变器和电机的参数。实验结果表明,该补偿方法有效地降低了相电流谐波,改善了相电流正弦度。This paper addresses the nonlinear factors of voltage source inverters and their impact on output phase voltage.To counter these effects,the study implements a vector control algorithm and an online compensation method that corrects q-axis current error.This method requires no additional hardware or knowledge of inverter and motor parameters.Experimental results verify that this method effectively reduces phase current harmonics and improves the sine of the phase current output.
