Basics: What Is The Role Of Capacitor?
Capacitor role:
Filtering role in the power circuit, the rectifier circuit to exchange into a pulsating DC, and in the rectifier circuit after the access of a large-capacity electrolytic capacitors, using its charge-discharge characteristics, so that the rectified pulsating DC voltage changes into a relatively stable DC voltage. In practice, in order to prevent parts of the circuit supply voltage changed due to load changes, so the output power and load power input generally has had dozens to hundreds of microfarads electrolytic capacitor. As the large-capacity electrolytic capacitor generally has a certain inductance, high frequency and pulse can not effectively filter out interfering signals, it has a parallel in his capacity both ends 0.001 - 0.lpF capacitor to filter out high frequency and pulse interference.
Coupling: In the low frequency signal transmission and amplification process, before and after the two circuits to prevent the static work point of interaction, often using capacitive coupling. Signal in order to prevent excessive loss of the low frequency components rhyme, generally the larger the total capacity of electrolytic capacitors used. The importance of
capacitor into the raging river to the lake, let it flow out, it seems calm and softened. Capacitor should be as a lake on the role of it. So do not clutter the current cleaner.
So-called capacitor is charged up and release of electronic components. The basic principle is the capacitor charge and discharge
Course, rectification, oscillation, and other role. Another capacitor structure is very simple, the main positive and negative electrodes and by the two
Caught in the middle of the dielectric composition, the capacitance type is mainly determined by the electrode and dielectric. In the computer system
Board, card, power supply circuit, the application of the electrolytic capacitors, paper dielectric capacitors and ceramic capacitors and other types of capacitors, and to
Mainly electrolytic capacitors.
Paper dielectric capacitor foil by two layers of positive and negative electrodes and a layer of insulation caught in the middle of the stencil foil composition and body split quartet built flat
Rectangle. Rated voltage is generally between 63V ~ 250V, capacity is small, basically pF (PF) level. Modern Paper
Medium capacitor As a result of hard plastic shell and resin sealed package, not easy to aging, but also because they basically work in the area of low pressure
And pressure values are relatively high, so are less likely to damage. The event was electric damage, the general appearance of symptoms for the capacitors made
Heat.
Ceramic capacitor is a metal electrode coated on both sides of tiles made of generally flat circular. Capacitance is small, both
In p F (skin micro-method) orders of magnitude. And because the medium is thicker insulation tiles, so the rated voltage is generally about 1 ~ 3kV,
Electrical damage will be difficult, usually only a mechanical damage. Very few in the application of computer systems, each circuit board, respectively,
Only about 2 ~ 4.
Electrolytic capacitor paper dielectric capacitor structure similar to and different as the two metal foil electrodes of different (so in electrolysis
Capacitors are divided into positive and negative, and generally indicate the negative), metal foil and paper at the two electrodes into a cylindrical volume, the mounted
Circular containing electrolyte aluminum bucket closed. Therefore, should the capacitor leakage, it is easy to cause electrolyte fever, from
Muster or arising shell burst phenomenon.
