降频 meaning in English
underclocking
Examples
- At last , the fit technology was applied into the system . 1 . base on the characteristics of cpu ( they can change the running state ) , and the system is parallel satellite - carried computer system , so divide them into three states : double run mode , single halt mode , power down mode
具体工作如下: 1 、根据cpu的可降频运行的特点,将其分为三种状态:双全速模式,单闲置模式和双闲置模式,降低功耗效果明显; 2 、根据系统可脱离i / o设备运行的特点,在系统运行时动态地给i / o设备供电。 - With the conduction property of the triggered thyristor and the intellective numerical controlled frequency reduction of the triggering pulse by mpu , we can divide alternating current into several complete sinusoidal waves to supply some loads . it can be made as a controller or a pcb ware , which is suitable for the air conditioning , machine tool and various instruments that require electric power or rotate speed adjustment
利用晶闸管的触发导通特性，用单片机对触发信号进行智能数字降频，可在交流电中切分出部分完整的正弦波形供负载使用，可以单独做成一台控制仪器或者作为一个控制电路板用于需要电功率和转速调节的空调、机床以及各类仪器设备中。 - Soft starters decline only the electric voltage and do not decline the frequency , and make the starting torque turn small , therefore the soft starters be applicable only to the induction motors which drive the low starting torque machine such as blower fan and pump . this paper designed a soft starter adopting the discrete frequency method to start induction motors . it declines not only the electric voltage , but also makes the frequency lower at the same time , so starting torque turns more
由于软起动器只降压不降频，电机的起动转矩较小，所以传统软起动器只适用于风机、水泵类低起动转矩的负载。本文设计并研制了一种采用分级变频方法的新型软起动控制器，在降压的同时实现有级变频，从而提高了异步电动机的起动转矩。
