采用g-h坐标下的SVPWM算法,以开关状态方程解的数目为依据,对作用时间的计算等问题进行了简化。在理论分析的基础上,对2种算法进行MatlabSimulink建模。结果表明60°坐标系下SVPWM算法的优越性。本文选用Cyclone II系列FPGA作为主控芯片,基于Quartus II开发软件设计流程及方法,用Verilog HDL语言设计各个模块。利用Quartus II软件仿真结果表明输出的驱动波形和电压波形达到了设计的要求。 Based on the SVPWM algorithm in g-h coordinates, the problem of calculation of working time is simplified based on the number of solutions of switch state equations. On the basis of theoretical analysis, the two algorithms are modeled by Matlab Simulink. The results show the superiority of SVPWM algorithm in 60 ° coordinate system. This article selects Cyclone II series FPGA as the main control chip, based on QuartusII development software design flow and method, each module is designed by Verilog HDL language. Simulation results using Quartus II software show that the output drive waveforms and voltage waveforms meet the design requirements.
