开关频率 [kāi guān pín lǜ]
[自] switching frequency
- 首先就是开关频率。
The first is switching frequency. - 其中尤其是开关频率优化中的零矢量交替相移空间矢量法具有开关频率更低，输出电压谐波更小的特点；
Especially the way of zero vector by turns of switch frequency optimized modulation has lower device switching frequency and lower harmonic of output voltage. - 同时，高速交流传动机车广泛采用高开关频率器件的脉宽调制（PWM）逆变器，使得逆变器输出脉冲具有陡上升沿。
Meanwhile, PWM inverters using high switching frequency device that shortens the rise time of PWM output pulse have been widely applied in high-speed AC driving locomotive.
