| 摘 要： | 分析了死区电压矢量和定子电流矢量的关系,由此得到一种根据重构电流矢量来补偿定子电压矢量的方法。在实现中采用了输出电压矢量脉冲宽度补偿策略,给出了软件实现流程图和实验波形。该方法实现简单,无需额外的硬件成本。实验结果表明,该方法补偿效果显著,有较强的工程应用价值。

| Abstract: | The relationship between the dead-time voltage sector and the stator current sector is analyzed and a method for compensating the stator voltage sector is proposed based on the reconstructed current.The strategy of compensating output voltage sector is taken in realization,furthermore the flow chart and testing waveform is presented as well.The method is convenient to realize and needs no additional hardware cost.The experimental results show that the compensation effects are remarkable. |
