Many different random PWM methods have been developed to reduce noise and suppress electromagnetic interference (EMI). A new dual randomized modulation of zero-vector and variable-delay is presented based on analysis and comparison of random PWM technologies.
从降低噪声和减少电磁干扰角度出发对各种随机PWM技术进行了分析和比较,在此基础上提出了一种零矢量-变延时的双随机PWM调制策略,该方法在简化数字化程序实现的同时,在调制比较低时有着独特的谐波频谱特性。
