Q:What is the principle of capacitance isolation?
When the capacitor is connected to the AC circuit, there is also a charging process in which the charge is stopped when the capacitor voltage is equal to the supply voltage, and then the power supply voltage drops and the capacitor begins to discharge.
Q:What is the capacitor, what is the use, where is there?
The role of the capacitor filter, coupling, bypass, decoupling function. Capacitors are mainly used for AC circuits and pulse circuits, in the DC circuit capacitors generally cut off the role of DC. Capacitors do not produce nor consume energy, are energy storage components.
Q:Why some Y capacitor is very small, and some Y capacitor is very large?
In line between the line of fire and zero line suppression capacitor, commonly known as X capacitance. As the location of the capacitor connection is also more critical, the same need to meet the relevant safety standards. X capacitance is also one of the safety capacitors. According to the actual needs, the capacitance value of the X capacitor is larger than the capacitance of the Y capacitor. However, it is necessary to connect a safety resistor in parallel with the X capacitor to prevent the charging and discharging of the power supply line.
Q:What is the relationship between capacitance and voltage?
when you charge 5v, want to be in the first The capacitor is full, the second capacitor half; if you charge a higher voltage 6v, then the first capacitor to diffuse out, the actual performance of the capacitor was breakdown!
Q:What is the use of capacitors?
As a passive component of the capacitor, its role is nothing more than the following; applied to the power circuit, to achieve bypass, decoupling, filtering and energy storage role, the following classification:
Q:What is the electrolytic capacitor inside?
Electrolytic capacitor features three: the price than other types have overwhelming advantages, because the composition of electrolytic capacitors are common industrial materials, such as aluminum and so on.
Q:Cd capacitance to express what
Mainly used in high voltage, high current and high pulse circuit, such as buffer, energy converter, switching power supply, inverter and inverter protection circuit, especially for IGBT, SCR, Darlington line For absorption capacitors.
Q:Capacitance for AC and DC effects?
Potential has a concept of space, referring to the electric field to a Coulomb charge from A to B work 1 joules, A on the B potential is 1 volt. The concept of potential for the circuit, specify a point of the circuit for the 0 potential, the other points are based on the point of the voltage is the potential of the other points. Electromotive force used in batteries, generators, is the power to generate voltage.
Q:What is the difference between the power capacitor and the complement?
In fact, in the case of three-phase imbalance, but also a total complement and sub-all have, the three-phase power factor, respectively, 0.53,0.67,0.71, then, in the 0.71 above this part, The reactive power required by the other parts of the two phases is compensated by tipping.
Q:Does anyone know the difference between the stray inductance of the capacitor and the parasitic inductance?
This impedance can not be ignored in the presence of high frequency current, with particular note that the bypass capacitor needs to pass through the two vias when connecting the power plane and the formation so that the parasitic inductance of the vias is multiplied.
