Briefly introduce the filter capacitor

Filter capacitor is a kind of energy storage device, which is usually installed at both ends of the rectifier circuit to reduce the AC ripple coefficient and improve the efficiency and stability of DC output. Briefly introduce the filter capacitor

Filter capacitor has the characteristics of electrode, we call it electrolysis. One end of the electrolytic capacitor is positive and the other is negative. The positive pole is connected with the positive pole of the rectifier output circuit, and the negative pole is connected with the negative pole of the circuit. In all the circuits that need to convert alternating current to direct current, setting filter capacitor can make the performance of electronic circuit more stable and reduce the interference of alternating current ripple to electronic circuit. The symbol of filter capacitor in circuit is generally expressed as "C". The larger the capacitance, the better the filtering performance. In order to obtain better DC stability coefficient, the capacitance is usually selected in hundreds or thousands of microns.

The capacitor is dry type DC high voltage capacitor. The utility model has the advantages of small volume, light weight, convenient carrying, small leakage current, shell insulation, etc. The new filling technology can ensure the stable and reliable operation of the capacitor. The capacitor can be used for filters and voltage multiplier capacitors in different DC tests.
