查询词典 capacitor

If a capacitor is connected to a battery, the electrons will flow out of the negative terminal of the battery and accumulate on the capacitor plate connected to that side.

如果电容器连接到电池上，电子将从电池的负极流出堆积在与负极相连的极板上。

The analysis results show that PAPF is effective for parallel resonance damping, but can not damp series resonance when capacitor current is not included in the detecting current. And when capacitor current is included in the detecting current, PAPF is prone to be unstable and can not damp parallel and series resonance.

分析表明，由于无功补偿电容器的影响，传统控制策略下的PAPF对系统谐振的抑制效果不理想，同时当检测的负载电流中包括无功补偿电容器电流时，系统还有可能出现不稳定的现象。

Another feature of electrolytic CAPACITOR s, both aluminium and tantalum, is that most of them are polarized and require a DC bias for correct operation - a reverse bias may do damage and will certainly increase leakage (unpolarized electrolytic CAPACITOR s, which may be biased in either direction, do exist but they are uncommon, and considerably larger than the polarized variety).

电解电容还有一个特点，那就是绝大多数都是有极性的，其两端必须施加直流电压才能正常工作。如果极性接反，电容就可能损坏，其漏电流也会增加。无极性电解电容虽然已经问世，但是相比之下不常用，而且外形尺寸也比有极性电容大。

This thesis has been discussed the Integrated Passive Devices including the capacitor and the inductor characteristics, as well as one of their variables such as the circle number, the width, the space, the radius and the capacitor area has been changed to investigate their scattering parameter, inductance, capacitance and Q-factor.

本论文内容主要是讨论整合式被动元件中的电感与电容之特性，并试著改变单一变因如圈数、线宽、线距、半径、及电容面积，并分别讨论其反射系数、电感值、电容值及品质因数。

This complements the reservoir capacitor with a choke and a second 滤波电容, so that a steadier DC output can be obtained across the terminals of the filter capacitor.

这补充一扼流和一个第二个的滤波电容的储层电容器，以便可以跨接线端与滤波电容器得到稳定的直流输出。

In high-voltage var compensation field, when switching the capacitor banks by mechanical switch, it is easy to bound when it closes and to restrike when it opens, and the mechanical switch can not be switched frequently. When switching the capacitor banks by electronic switch in series, it needs dynamic and static voltage sharing circuit and synchronous triggering circuit. It leads to complex structure and high cost.

为解决当前高压无功补偿领域采用常规机械开关投切电容器组开关合闸时触点弹跳产生过电压，分闸时易重燃及不可频繁操作，而采用串联固态电子开关需要相应的动、静态均压及同步触发电路导致系统结构复杂且成本较高的问题，提出一种基于新型高压投切开关的高压动态无功补偿装置。

In a capacitor start motor, a starting capacitor is inserted in series with the startup winding, creating an LC circuit which is capable of a much greater phase shift (and so, a much greater starting torque).

在电容启动电机，启动电容与启动绕组串连在一起，从而形成一个LC电路，这个电路有很好的相移（因此也有很好的启动扭矩）。

But the using life of the smoothing capacitor is greatly reduced be- cause of the heat generated by the excessive ripple current on the ESR of the smoothing electrolyte capacitor.

但是电解电容器最大的缺点就是使用寿命问题，特别是在高温条件下尤为明显，电解电容器的寿命直接影响着变频器/逆变器的使用寿命。

Because a bulk smoothing capacitor is usually installed on the DC side of many AC to DC converters, the characteristics of harmonic loads will be influenced by this capacitor. Nowadays, shunt active power filters can't reduce harmonics effectively for this voltage type harmonic-producing load. Therefore, a series active power filter is designed to meet the requirements of voltage-sourced harmonic loads. Both source current and load voltage are detected in order to reach the compensation voltage for the SAPF.

由於许多交直流电源转换器均在直流端并联一直流电容以作为稳压之用，此大电容将造成负载谐波特性的改变；此类谐波源负载，如果使用现今常见的并联型主动式电力滤波器并不能很有效解决此类谐波问题；因此本文将采用串联型主动式电力滤波器，并配合同时量测电源电流及负载电压的混合式控制模式，即可有效解决此类谐波问题。
