Q:Why use inductance
The basic function of inductive argument: effect of filtering, oscillation, delay, wave trapping image:
Q:What is the inductor
If the inductor is in the absence of an electric current, it will try to block the current flowing through it when the circuit is switched on; if the inductor is in the state of current passing, it will try to keep the current
Q:Effect of inductor
Inductor has a certain inductance, it only prevents the current changes
Q:What is the difference between a mobile power supply and a power adapter?
Similar SSYMB brand, there are two kinds of charging methods: one is charged by USB cable; one is charged by the power adapter.
Q:What is the difference between a power adapter and a voltage regulator?
The power adapter (Power adapter) is the power supply equipment transform small portable electronic equipment and electronic appliances
Q:Linear adapter and switching power adapter
But the linear power supply EMI is low, but the switching power supply EMI is higher, especially the small power.
Q:Is the inductor inductor
Divided into inductive and capacitive reactance, classification and comparison of science is impedor (inductors) and capacitive devices (capacitor) referred to as the reactor, but because of the past with the first inductor, and is called the reactor, so the capacitor is now known as capacitive device, and reactor as an inductor.
Q:How to classify inductors
The adjustable inductor is divided into a magnetic core adjustable inductor, a copper core adjustable inductor, a sliding contact adjustable inductor, a series mutual inductance adjustable inductor and a multi tap adjustable inductor.
Q:Main parameters of inductor
Usually, the more coils, the more dense the winding, the greater the inductance
Q:What is the substitution principle of inductance?
The inductor is similar in structure to the transformer but has only one winding.
We are a focus on the production of switching power supplies and power adapters and other power products for high-tech enterprises. Shenzhen power adapter, power adapter manufacturers, switching power adapter, switching power supply manufacturers, charger manufacturers, USB power adapter, 12V power adapter
