We often see a cable called "power adapter" on the market, but do you have any understanding for it?
So let me take you into the "power adapter"!
Power adapter is a small portable electronic equipment and electrical and electronic power supply conversion equipment, generally by the shell, transformer, inductor, capacitor, control IC, PCB board and other components, its working principle from AC input to DC output; According to the connection mode can be divided into wall type and desktop type. Widely used in security cameras, set-top boxes, routers, light bars, massagers and other equipment.
Above we have a general understanding of the power adapter, but I believe you will still have a lot of questions about the power adapter, and then let me answer it for you one by one!
1. What does mean of the nominal voltage of the power adapter (hereinafter referred to as the power supply) ?
First of all, the nominal voltage of the general power supply refers to the open-circuit output voltage, that is, the voltage when the outside is not connected to any load and there is no current output, so it can also be understood that this voltage is the upper limit of the output voltage of the power supply.
In the case of the use of an active voltage regulator inside the power supply, even if the mains voltage fluctuates, its output is a constant value, like the general small transformers on the market, such as the Walkman power supply, if the mains fluctuations, the output of the power supply will not fluctuate.
Generally speaking, the real no-load voltage of the ordinary power adapter is not necessarily completely consistent with the nominal voltage, because the characteristics of the electronic components can not be completely consistent, so there is a certain error, the smaller the error, the higher the consistency requirements for the electronic components, the higher the cost of production, so the price is more expensive.
2. Are the same nominal voltage power supply, the output current is different, can it be used in the same notebook?
The actual current depends on the load at the same voltage. When the notebook is running at high load, the current is larger, and when the notebook enters standby, the current is smaller, and the power supply with large nominal current has enough current margin.
On the contrary, there is no problem with someone using 56w power instead of 72w, the reason is that the design of the power adapter usually has a certain margin, and the load power is less than the power supply power, so this substitute is feasible in general use, but the remaining power supply power margin is very small, once your notebook is connected to a lot of peripherals, such as two usb hard drives, Then the cpu is running at full speed, and there is a base, which comes with a optical drive reading disk at full speed, plus charging the battery at the same time, it is estimated to be dangerous.
Therefore, it is best not to use a small current power supply instead of a large current power supply.
3. The nominal voltage is much higher than the voltage of my laptop battery, will it be OK?
First of all, it is important to know that the power supply to the laptop is different from the battery to the laptop power supply.
Battery power supply, the output of the battery is pure DC, the voltage of the battery is neither possible nor need to be designed very high, the chemical characteristics of the lithium battery determines the output voltage of a battery cell can only be about 3.6V, so many batteries are the use of three series, 10.8V has become a very popular battery voltage. The nominal value of some batteries is slightly larger than the integer multiple of 3.6V, such as 3.7V or 11.2V, etc., in fact, in order to protect the battery.
Power supply, the situation is more complicated, first of all, you need to add further voltage regulation filter to ensure stable work in the case of power performance is not very good, the voltage after voltage regulation is divided into two parts, one way to supply power to the notebook, the other way to charge the battery, the part that supplies power to the notebook is the same as when the battery is powered. The part that charges the battery needs to be added to the battery through the battery's charging control circuit, the control circuit can be very complex, so the power supply voltage must be greater than the battery voltage to have the full ability to supply to the charging control circuit units. The actual voltage applied to the cell will never be the nominal voltage of your power supply. Don't worry.
