Do you know that there is a component called a filter capacitor in variable frequency power supplies?
　　The filtering capacitor,also known as the DC capacitor,works in a variable frequency power supply by being used in the rectification circuit of the power supply to filter out AC components.Make the output DC smoother.Featuring small size,light weight,and convenient installation.
　　There are many internal components in variable frequency power supplies,among which the filter capacitor is one of the most important components.The filter capacitor is mainly installed at both ends of the rectifier circuit,and its function is to reduce the coefficient of AC artery ripple and improve efficient and smooth DC output.
　　So,what are the main functions of filter capacitors?
　　The filtering capacitor is mainly used to filter out the cancellation components.Of course,for those precision circuits,using a combination of parallel capacitor circuits can improve the efficiency of the filtering capacitor,because the filtering capacitor is used in the DC part of the variable frequency power supply.
　　So now let's talk about the maintenance of the filter capacitor.We know that variable frequency power supplies are also electronic products,and the filter capacitor is an internal component.After using it for a long time,it is inevitable that there will be problems or need to be replaced.As long as it is a spare part product that has been used for a long time,its performance will age or decrease to some extent.In order to not affect the use of variable frequency power supplies,it is recommended that everyone regularly inspect them every quarter or every year.When the capacity of the filter capacitor has decreased by more than 20%,it should be replaced to ensure the normal operation and long-term use of variable frequency power supplies.
