| 摘 要： | 为使五相电压源逆变器同时获得最大电压利用率及最小输出电压谐波,在分析两种SVPWM算法调制机理的基础上,设计了一种改进的相邻最近四矢量SVPWM算法。该算法在调制比为0~1.051 4范围内,通过消除谐波空间合成矢量,使得输出电压谐波为零;在调制比为1.051 4~1.23 1范围内,通过优化重新分配电压矢量作用时间来合成参考电压矢量,保证了谐波空间的合成矢量最小,使逆变器工作在最优状态。构建了五相电压源逆变器仿真模型以及FPGA实验平台,仿真和实验结果表明:在整个线性调制范围内,优化算法能够使五相电压源逆变器的输出电压谐波最小。

| Abstract: | To make sure that five-phase voltage source inverter(VSI) get maximal DC voltage utilization and minimal output voltage harmonics,a novel space vector pulse width modulation(SVPWM) algorithm using four nearest space vectors was proposed.When modulation ratio m is between 0 and 1.051 4,harmonic in output voltage could be restricted to zero by eliminating the voltage vectors in harmonic space.When m is between 1.051 4 and 1.23 1,the active time of space vectors was optimized to minimize the voltage vectors in... |
