【摘要】 多电平逆变器空间矢量的发生需要形成复杂的逆变器驱动信号。本文介绍采用FPGA与DSP的组合来实现三电平逆变器空间矢量发生的一个方法。其设计思想是DSP通过算法生成“开关状态码”,FPGA对这些“开关状态码”进行译码并得到逆变器中12个开关元件的驱动信号,从而形成空间矢量。这种三电平逆变器空间矢量发生器的实验结果体现了该方法的可行性和简易性。更多还原

【Abstract】 The generation of the space vectors of multi-level inverter requires the formation of a group of complex driving signals. The paper introduces a method that realizes the generation of the space vectors of a 3-level inverter by using a combination of DSP and FPGA. A DSP produces the "switching states codes", and a FPGA translates those codes into signals driving the 12 switches in the inverter, thereafter forming the space vectors. The experiment using such a 3-level inverter space vector generator exhibited feasibility and simplicity of this method.更多还原
