Q:Does anyone know the difference between the stray inductance of the capacitor and the parasitic inductance?
With the increase in stray inductance, IGBT turn-on loss will be reduced, the diode loss will increase. Stray inductance may also cause oscillations, such as oscillations caused by current mutations, which may result in limited device use due to EMI or overvoltage limits.
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:Is the capacitor attached to the carbon foil positive?
Electrolytic capacitors of the positive plate with aluminum foil, immersed in the electrolyte for anodic oxidation treatment, aluminum foil surface will produce a layer of aluminum oxide film, the thickness is generally 0.02 - 0.03μm. This layer of oxide film is positive and negative insulation between the plates.
Q:How to judge the capacitor is good or bad?
Measurement, the choice of multimeter R × 10k block, with two test leads were any then the capacitor of the two pins, the resistance should be infinite. If the measured resistance (pointer to the right swing) is zero, then the capacitor leakage damage or internal breakdown.
Q:How does the capacitor work? What does it do?
Capacitance works: the principle of charge and discharge simply put the capacitor is the two poles charged or discharge, that is, charge diffusion. Charge and discharge capacitors should be connected in series, can be connected in parallel; it is the basis of other properties of capacitance. The phenomenon of intermittent communication is the embodiment of charge and discharge, if it is DC, charged to stop, the capacitor charged; if it is alternating current, is constantly charging discharge. Complete the transmission of AC.
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 difference between polyester film capacitors and ceramic capacitors?
Ceramic dielectric (type CC) ceramic material dielectric constant ε is very large, so the capacitor volume can be made very small.
Q:What kind of capacitance can be divided into?
Oil and paper capacity. It is the paper dielectric capacitor immersed in a specially treated oil, can enhance its pressure. It is characterized by large capacity, high pressure, but the larger. Glass glaze capacitors to glass glaze for the media, with the advantages of ceramic capacitors, and smaller, high temperature.
Q:What are the differences between capacitors and capacitors?
There is a capacitor is a unit of the capacitor is a substantial object ah
Q:Why does the circuit current gradually decrease when charging the capacitor?
Why does the circuit current gradually decrease when charging the capacitor? Because the charge began to charge the capacitor, the capacitor two electrode plate charge began to zero, the electrostatic field is zero, the absorption of electrons is not exclusion, the performance of the phenomenon is the beginning of the charge when the circuit current is very large, with the capacitor The charging time increases, there will be more and more charge adsorption on the capacitor two electrode plates,
