Q: Use capacitance to do transformer how to calculate: Although the current flowing through the capacitor has 70mA, but in the capacitor does not produce power, because if the capacitor is an ideal capacitor, the current flowing through the capacitor for the virtual part of the current, the work done by the reactive power.

Q: How to use the capacitor: Circuites that are forbidden use: Even if the customer installs a solid-state aluminum capacitor in strict accordance with the welding conditions we have given, the leakage current of the solid-state aluminum capacitor may also increase or even increase significantly.

Q: How to judge the capacitor is good or bad?: Multimeter selection R × 1k block. Both triodes have a beta value of 100 or more and a small penetration current. Can choose 3DG6 and other types of silicon transistors composed of composite pipe. The multimeter's red and black test leads are connected to the emitter e and collector c of the composite tube, respectively.

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?: To charge the power cord for long periods of time. The safety standard stipulates that the voltage (or ground potential) charged at both ends of the power cord plug must be less than 30% of the original rated operating voltage within two seconds when the machine power cord is in operation.

Q: On the ground resistance, what role the capacitor: The capacitor used in the bypass circuit is called the bypass capacitor. If the signal is removed from the signal in the circuit, the bypass capacitor circuit can be used. According to the frequency of the removed signal, there is a full frequency domain (all AC signals ) Bypass capacitor circuit and high frequency bypass capacitor circuit.

Q: How does the capacitor work? What does it do?: The bypass capacitor is an energy storage device that provides energy to the local device, which can equalize the output of the regulator and reduce the load demand. 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 as close as possible to the load device's power supply pin and ground pin.

Q: Why does the circuit current gradually decrease when charging the capacitor?: due to the increase in the number of charge, the electrostatic field field strength will gradually increase, increasing the field strength caused by the absorption of electrons to produce exclusion, So that the number of adsorbed charges gradually reduced, the number of charge to reduce the performance of the phenomenon that the charging current is gradually reduced. When the number of charges on the two electrode plates of the capacitor reaches a gradually increasing field strength constraint, the amount of charge is not increased and the equilibrium state is reached, that is, the charge saturation current is zero.

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?: Different components of the ceramic, its dielectric constant and temperature coefficient is different, the temperature coefficient range is wide, easy to make different temperature coefficient of the capacitor, used as a temperature compensation capacitor.
