SPWM数字化自然采样法存在脉冲竞争现象。
There are some pulse competition in the digital natural sampling based SPWM.
当采样频率比较高时，数字化自然采样法的频谱分布与自然采样法的频谱分布类似。
When sampling frequency is quite high, frequency spectrum distributing of digital natural sampling and natural sampling is similarity.
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.
