摘　　要：按电流方向的不同,分析了永磁同步电机死区效应对逆变器输出的影响,提出了一种有效改善死区效应引起电流畸变的在线补偿方法,不仅实时性高、计算量小,而且其算法不需要任何额外的硬件电路和离线的实验测量。仿真和实验结果证明了理论分析和补偿方法的正确性。The impact of the dead-zone effect on inverter output voltage is analyzed in the different current direction. An affective online compensation algorithm to improve the output current distortion is put forward. It is highly-real-time, needs less computation and needs not any additional hardwarecircuits and off-line experimental measurement. The result of simulation and experiment proves correctness of the theoretical analysis and the compensation algorithm.
