| 中文摘要 | 死区补偿和最小脉宽限制减小了空间矢量脉宽调制的线性调制区。针对死区补偿,提出一种改进的基于脉冲的死区补偿(PBDTC)方法,在复杂可编程逻辑器件中整合了死区插入和死区补偿功能,避免了传统PBDTC的双计算周期和输出占空比限制。针对最小脉宽限制,提出叠加零序分量的方法,使线性调制区的损失降低到50%以下,在过调制区可以平滑过渡到六方波模式以输出最大基波电压。该方法易于实现,应用场合广泛。实验结果验证了它的有效性。; Dead-time compensation and minimum pulse-width limitations lead to losses in the linear modulation region of space vector modulation.A pulse-based dead-time compensator developed to improve the dead-time compensation integrates the dead-time insertion and compensation into a programmable logic device which avoids double computing cycles and duty-cycle limitations caused by the traditional design.A zero-sequence superposition method developed to minimize the pulse-width limitations reduces the losses in the linear modulation region to less than 50% of the traditional method.The method also smoothly transitions into the six-step mode to produce the largest fundamental voltage.The method is easy to implement and can be widely applied.Experimental results fully support the conclusions.; 国家自然科学基金资助项目(50807028) |
