文章提出了一种改进型正弦波脉宽调制(SPWM)对称规则算法。
In this paper, the Sine Pulse Width Modulation (SPWM) technology is investigated, and an improved SPWM algorithm is presented.
与傅里叶分析中使用的无限重复的正弦波不同，小波常常是不规则的和非对称的，随着离中心点越来越远，其数值逐渐靠近零。
Unlike the sinusoidal, endlessly repeating waves used in Fourier analysis, wavelets are often irregular and asymmetric, with values that die out to zero as they move farther from a central point.
自然采样法产生的SPWM脉冲效果最接近正弦波，但工程中不利于实时控制，在实际中常采用的规则采样法精度不够高。
As the natural sampling method generating SPWM pulses closer to sine wave is impractical in real-time control, the regular sampling method with poor precision is usually adopted in practical projects.
