摘　　要：分析了一种三电平SVPWM新型算法,通过选择合适的坐标系,可以避开复杂的三角函数及查表计算,直接识别出参考矢量所处的区域,并求取基本矢量的作用时间,从而降低了对处理器性能的要求。该法只涉及少量的逻辑运算,适合于FPGA进行实现。最后在Xilinx公司XCS3400FPGA上对该算法进行实现,并在硬件平台上进行实验,实验结果验证了该算法的正确性。A new three-level SVPWM algorithm was introduced, and presented a circuit realization based on FPGA. By choosing appropriate coordinate,the location of the reference voltage and the duration of basic vectors can he identified directly without complex trigonometric functions and look-up tables,thus the performance of processors can be reduced. For only some logical operations are involved,it can be realized by FPGA easily. The proposed algorithm was realized using a XC3S400 FPGA from Xilinx, Inc. Experimental results are then presented for verification.
