摘　　要：提出了一种适合硬件实现的三电平空间矢量调制优化算法。该算法利用三电平空间矢量图的几何对称性,把三电平空间矢量的计算集中在一个扇区内完成,有效地减少三电平空间矢量的计算量,从而降低了算法实现所需硬件资源的需求。根据该优化算法,本文采用硬件描述语言在单片现场可编程序逻辑阵列上实现三电平空间矢量调制,同时给出具体设计步骤和关键设计考虑。仿真和实验验证了该算法的正确性以及硬件实现的快速性。This paper presents an optimized algorithm of three-level space vector PWM suitable for hardware implementation.The proposed algorithm accomplishes all the computation of three-level SVPWM algorithm in one sector by taking use of the geometrical symmetry of the space-vector diagram of the three-level topology,which reduces the computation amount of three-level SVPWM.Thus it reduces the hardware resources required by hardware implementation of the algorithm.Based on the proposed algorithm,the paper realizes the three-level SVPWM on a single field programmable gate array device using the hardware description language.The paper also gives the detailed design procedures and some key design considerations.Simulation and experimental results are given to verify the correctness of the proposed algorithm and quickness of the designed hardware.
