6) Acoustic noise
声学噪声
1.
Random pulse width modulation (RPWM) can make the harmonic spectrum of inverter output voltage be continuously distributed without affecting the fundamental frequency component, and thus the acoustic noise and mechanical vibration of an inverter-fed AC mot or drive are greatly reduced.
应用随机脉宽调制(pulse width modulation,PWM)方法可以使逆变器的输出电压频谱呈连续分布而不影响基波分量,这样由逆变器供电的电动机的声学噪声和机械振动就会大大减小。
