Q: What is the role of inductance in the power supply: The effect of inductance is to prevent the change of electric current

Q: Main parameters of inductor: Inductance inductance of the size, mainly depends on the number of coils (turns), winding method, with or without the core and core materials, etc.

Q: What is a power adapter, what is the use of: generally consists of a shell, a power transformer and rectifier circuit, according to the type of output can be divided into AC output type and DC output type; according to connection can be divided into the plug wall and desktop

Q: What is the difference between a power adapter and a voltage regulator?: Straightforward can be understood as a voltage converter, such as the 110-220 AC voltage into a fixed DC voltage

Q: Inductance has no direction?: To discuss the situation: in the general filter circuit, the direction is not large; but if used in the PWM output inductance, this direction is too critical.

Q: What are the two functions of the inductor in the circuit: it will hinder the current increase of electric energy in the magnetic field in the form of temporary storage

Q: Inductance is what concept?: Usually, the more coils, the more dense the winding, the greater the inductance.

Q: What is inductance effect: According to Lenz's law, the flux tends to resist the change of electric current by the induced voltage (back EMF).

Q: What is the difference between a mobile power supply and a power adapter?: Adapters are constantly transformed and cannot be fully charged

Q: The value of the inductance is determined by what: It was also reduced the Q value of the inductor, the purpose is to avoid high frequency resonance / gain is too large
