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: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: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:What is the difference between an inductor and a sensor?
inductors are used in passive mode, sensors are usually used to measure and feedback
Q:Inductor and inductor coil is not a concept
So the inductor and inductor coil can be considered the same, some different
Q:What are the two functions of the inductor in the circuit
The role is to impede the flow resistance current power consumption for the logo, change of inductance to impede current is purely to increase the current change
Q:What is the inductor
The inductor is similar in structure to the transformer but has only one winding
Q:How to select power adapter
the rated output current of the power adapter shall not be less than the rated input current of the computer.
Q:How to determine whether the computer adapter is available
Always worried that will affect the computer, so full after I put the adapter pull from the computer
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.
