As the frequency of the AC component increases, the DC meter response decreases, until at some frequency only the average input voltage will be displayed.
当交流分量的频率增加时，直流仪表的响应就会变得不够快，直到在某一频率时，仪表只能显示出输入电压的平均值。
In a dc-dc converter with a given input voltage, the average output voltage is controlled by controlling the switch on and off durations (ton and toff).
在一个给定了输入电压的直流-直流变流器中，输出的平均电压是通过控制开关的导通和关断时间来控制的。
Controlling the DC capacitor average voltage and fluctuant voltage at an adequate value is an important factor which guarantees the excellent compensation characteristics of shunt active filter (APF).
控制逆变器直流电容的平均电压与电压波动为适当值是保证并联型电力有源滤波器具有良好补偿性能的一个重要因素。
In dc-dc converts, the average dc output voltage must be controlled to equal a desired level, though the input voltage and the output load may fluctuate.
对于直流-直流变流器，虽然输入电压和输出负载会波动，直流输出电压必须控制在一个希望的水平。
