查询词典 mica capacitor

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。

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。

20 Output smoothing In a practical circuit, when a capacitor is directly connected to the output of a bridge, the bridge diodes must be sized to withstand the current surge that occurs when the power is turned on at the peak of the AC voltage and the capacitor is fully discharged .

在实际电路中，当一个电容器直接连接到桥式整流器的输出端时，桥式结构中的二极管必须能够承受交流电压峰值时开启电源和电容完全放电所产生的电流浪涌。
