Can high voltage ceramic capacitors be used in AC applications?

The high-voltage ceramic capacitor is a kind of ceramic capacitor. It is different from the ordinary ceramic capacitor. It is used in high-voltage ceramic capacitors. Generally, high-voltage ceramics are used in the measurement, energy storage and partial pressure of power systems. Chip capacitor. It is made by pressing a high dielectric constant capacitor ceramic (barium titanate titanium oxide) into a circular tube, a disk or a disk as a medium, and plating the silver on the ceramic as an electrode by a fire infiltration method to form a high pressure porcelain. Chip capacitors. Can high voltage ceramic capacitors be used in AC applications? The following is for everyone to answer.

In fact, high-voltage ceramic capacitors can be used in AC, and it will not work when used in DC. This is determined by the DC-connected AC characteristics of the capacitor, and it has a high loss of capacity loss with temperature and frequency, and a special series structure. Suitable for high voltage and long-term operational reliability, high current climb rate and suitable for high current loop non-inductive structure.

It should be noted that because of the high voltage, high frequency of the power system, the large voltage/current of the lightning strike in the outdoor environment, and so on, various factors have caused the high-voltage ceramic capacitors to have strict requirements in research and development and production. To have strong stability. At the same time, the measurement, energy storage, partial pressure and other products require high precision, which is zero for the partial discharge of the high voltage ceramic capacitor in this environment. Therefore, it is necessary to select high-quality high-voltage ceramic capacitors produced by reliable manufacturers, otherwise the consequences of using inferior capacitors are unimaginable.
