Problems solved by technology

However, since the film capacitor is greatly affected by the environmental conditions during operation, in order to ensure that it can work safely in the circuit where it is located, the film capacitor has to be derated, or additional equipment or devices must be added to avoid the film capacitor. A safety failure occurs, which seriously affects the working efficiency of the capacitor and also increases the cost

Description

technical field [0001] The invention relates to the technical field of power electronics, in particular to an intelligent capacitor, an intelligent capacitor control system, a method, and power equipment. Background technique [0002] Capacitors are one of the common electronic components widely used in power electronic equipment. As a device that can accommodate charges, capacitors are widely used in DC blocking, coupling, filtering, etc. in circuits. According to different dielectrics, capacitors can be divided into many types. For example, a film capacitor is a capacitor with a plastic film as its dielectric. [0003] In general, film capacitors have the advantages of non-polarity, high insulation resistance, excellent frequency characteristics, and small dielectric loss, and have been widely used in various power electronic devices since they appeared. However, since the film capacitor is greatly affected by the environmental conditions during operation, in order to ens...
