摘　　要：介绍了一种新型的五电平逆变器电压空间矢量脉宽调制(SVPWM)算法,该算法中不含复杂的三角函数运算,因此便于利用FPGA实现。设计了一种基于DSP和FPGA的硬件控制电路,其中FPGA主要用于实现SVPWM算法。给出了该算法利用FPGA实现的具体方法和步骤,并且利用Quartus II软件对该算法进行了仿真和实验验证。仿真和实验结果与理论计算相符,验证了本设计是正确且有效的。A novel algorithm of space vector pulse width modulation（SVPWM） for five-level inverter, without contain complex trigonometric function calculation, was introduced. Then FPGA was used. A control circuit based on DSP and FPGA was designed, and the FPGA was used to implement the SVPWM algorithm. The implementation approachs and concrete steps for the algorithm by used of FPGA were given, and the Quartus II software was used to simulated and experimental for the algorithm.The simulation and experimental results were consistent with the theoretical calculation, it showed that the design was correct and effective.
