为了避免复杂的三角函数和求根运算，便于数字信号处理器的实时运算，提出一种新 的SVPWM算法。采用SPWM中调制波与载波相比较的规则采样思路，通过在静止坐标系下直接 计算每个参考电压矢量所对应的三相调制波的函数值，进而得到每相电压在一个PWM周期中的 占空比．该算法的主要特点是计算简单，只需要普通的四则运算，适用于数字化系统。在扇区划 分和占空比饱和的处理上较传统SVPWM算法更简便，且过调制范围也略有拓展，具有很大的实 用性。仿真和实验结果证实了该算法的有效性。(In order to avoid complex trigonometric and root operation, ease of operation, real-time digital signal processor, propose a new SVPWM algorithm. Using SPWM modulation wave in comparison with the carrier' s regular sampling ideas, through the stationary coordinate system directly calculated for each reference voltage vector corresponding to the phase modulation wave function value, and then get each phase voltage in a PWM period accounted for air ratio. The main features of the algorithm is to calculate simple and requires only ordinary arithmetic for digital systems. Saturation in the sector division and duty cycle of the treatment more convenient than traditional SVPWM algorithm, and also a slight over-modulation range expansion, with great practicality. Simulation and experimental results confirm the effectiveness of the algorithm.)
