Electric power of high voltage capacitor

In electronic circuits, high voltage capacitors are used to block DC, as well as to store and discharge charge to act as a filter to smooth out the output ripple signal. Small-capacity capacitors are commonly used in high-frequency circuits such as radios, transmitters, and oscillators. Large-capacity capacitors are often used for filtering and storing charge. Usually, capacitors above 1μF are electrolytic capacitors, while capacitors below 1μF are mostly ceramic capacitors.

Of course, there are other things, such as monolithic capacitors, polyester capacitors, and small-capacity mica capacitors. The electrolytic capacitor has an aluminum case filled with electrolyte inside and leads two electrodes as positive (+) and negative (-) poles. Unlike other capacitors, their polarity in the circuit cannot be connected incorrectly. The capacitor has no polarity.

Because many of the devices on the power to convert electrical energy into other ways are called electric loads, such as many electric motors. Because the communication current through the rational load appliance lags behind the two connected communication voltages, the device that converts other ways into electrical energy is called the power supply. The apparent power of the apparent power S) is converted into useful Energy (active power P), the ratio of the two is called the power factor Cos.

Cos=P/S puts the high-voltage capacitor in a rational load, because the communication current through the capacitor leads the voltage one point of view, so that the angle between the total current and the voltage is reduced, the power factor is improved, and then the utilization of the power can be improved, and the line can be cut. damage.
