摘　　要：空间矢量脉宽调制算法是电压型逆变器控制方面的研究热点,广泛应用于三相电力系统中。基于硬件的FPGA/CPLD芯片能满足该算法对处理速度、实时性、可靠性较高的要求,本文利用Verilog HDL实现空间矢量脉宽调制算法,设计24矢量7段式的实现方法,对转速调节和转矩调节进行仿真,验证了设计的实现结果与预期相符。Space vector pulse width modulation algorithm is a research focus in voltage inverter controlling. And it has been widely used in three-phase power system. Hardware-based FPGA/CPLD chip can meet the high requirements in processing speed, real-time, and reliability of the algorithm. A 24-vector 7-segment implementation method was designed for the Space Vector Pulse Width Modulation algorithm with Verilog HDL. Speed and torque adjusting process were simulated, and the results verified the design.
