What is the role of a capacitor in a power supply?
As one of the passive components of the capacitor, its role is nothing more than the following: 1. When a capacitor is used in power supply circuits, its major function is to carry out the role of bypass, decoupling, filtering and energy storage. Filtering is an important part of the role of capacitors. It is used in almost all power circuits.
What is the function of a capacitor?
Capacitors are widely used to realize many electrical functionalities. As one of the passive components of the capacitor, its role is nothing more than the following: 1. When a capacitor is used in power supply circuits, its major function is to carry out the role of bypass, decoupling, filtering and energy storage.
What type of electrolytic capacitor is used?
Aluminum electrolytic capacitors with a voltage rating of 40 to 450 VDC and a capacitance between 220 and 150 000 uF (such as EP43’s B43504 or B43505) are more commonly used. According to different power requirements, devices are sometimes used in series, parallel or a combination of them.
What is a filter capacitor?
Specifically used in filtering, a large capacitor (e.g. 470uF) filters low frequencies, and a small capacitor (e.g. 120pF) filters high frequencies. It is very common to compare the filter capacitor to a “reservoir”.
Can a bypass capacitor be charged and discharged?
Just like a small rechargeable battery, the bypass capacitor can be charged and discharged to the device. To minimize the impedance, the bypass capacitor should be placed as close as possible to the power supply pin and ground pin of the load device. This can prevent ground potential rise and noise caused by excessive input value.
Why is a capacitor connected in parallel with a resistor?
A capacitor is connected in parallel with the resistor. Because a capacitor of appropriate capacity has small impedance to the AC signal, this reduces the coupling effect caused by the resistance, so this capacitor is called a decoupling/bypass capacitor.
