Q:How to test the power adapter
if possible, can be appropriate resistance as a false load, it can be generally choose to fake the load resistance
Q:What is the power adapter
The power adapter (also called the external power switch power adapter)
Q:Why use inductance
The basic function of inductive argument: effect of filtering, oscillation, delay, wave trapping image:
Q:What is the role of inductance in the power supply
AC resistance: in the AC circuit, the inductance will have an impedance, that is, XL, the current of the circuit will become smaller, a certain degree of obstruction to the exchange.
Q:Is the inductor inductor
However, charged straight conductor inductance is small, the magnetic field generated by the strong, so the actual reactor is conducting wire into a solenoid, said hollow reactor; sometimes in order to make the solenoid has larger inductance, then inserted into the core in the solenoid, said iron core reactor.
Q:Inductance works?
Also refers to the use of this property made of components. Inductor and transformer (inductor) are insulated conductor (e.g. enameled wire, wire etc.) electromagnetic induction element formed by winding
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 Australia's power adapter the same as Europe?
Voltage is 240V, voltage is based on the country, China is 220V, the United States and Canada is 110V
Q:Effect of inductor
Inductor has a certain inductance, it only prevents the current changes
Q:Laptop power adapter are AC-DC dual-use
General notebook power adapter are DC output, AC DC converter.
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
