| 摘 要： | 分析了变频器的死区效应以及SVPWM算法中电压矢量、电流矢量与功率因数角三者的关系,并由此得到一种基于功率因数角预测电流矢量的死区补偿方法。采用输出电压矢量脉冲宽度补偿策略进行死区补偿,最终给出实验波形。实验结果表明,该方法补偿效果明显,有较好的实用价值。

| Abstract: | The paper analyzed the dead-time effect of inverter and the relationship among voltage vector,current vector and power factor angle of the space vector pulse width modulation(SVPWM),then a method for dead-time compensation was proposed based on predicting current vector by power factor angle.The strategy for compensating output voltage sector was taken in realization,and the test waveform was showed at last.The method is convenient to realize.The experimental results show that the compensation is remarkable. |
