Q:How to learn the inverter debugging and design parameters
Personally think it is relatively simple, and now the inverter has been more intelligent, and some simple applications, and even do not need to set the parameters.
Q:Laptop power adapter (no power supply, but indicator light)
There may be reasons for the power adapter, there may be a computer can not identify the power supply is battery-powered or AC power. These are just speculated by your phenomenon, if you are better in the warranty period to the customer service test, so the best
Q:Motor a speed, the inverter will burn what is going on, the inverter is a large yuan
If you buy the inverter and the motor can match, it is certainly the quality of the inverter.
Q:Inverter principle eff23
Frequency conversion technology is the need for stepless speed of AC motor was born. Since the 1960s, power electronic devices have experienced SCR (thyristor), GTO (gate can be turned off thyristor), BJT (bipolar power transistor), MOSFET (metal oxide field effect transistor), SIT (electrostatic induction transistor) Development of SITH (Electrostatic Inductive Thyristor), MGT (MOS Control Transistor), MCT (MOS Control Thyristor), IGBT (Insulated Gate Bipolar Transistor), HVIGBT (High Voltage Insulated Gate Bipolar Thyristor), Device Update The power of electronic transformation technology continues to develop.
Q:What is the adapter?
USB adapter Buy a USB adapter: Audio-Video Adapter: Also offers the following types of audio-video adapters: O DVI to HDMI audio video adapter O DVI to VGA audio video adapter O RCA adapter O SCART adapter O XLR adapter O audio adapter
Q:Do not the laptop directly connected to the power adapter?
"Notebook do not power adapter", can only use the internal lithium battery power supply work. It can not directly use 220V AC power supply for it. 1, because the notebook product design power supply standard, is to use the matching power adapter power supply. That is, the power adapter will 220V civilian AC, rectifier filter, and then converted to low-voltage 19V DC, for the notebook to provide power supply;
Q:Laptop power adapter output voltage is not the same as the current? What's the effect?
so this replacement is generally feasible in the general use , But the remaining power supply power margin is very small, once your books took a lot of peripherals, such as two usb hard drive, and then cpu full speed operation, and then a base, the above to drive a full speed to read the disk, plus While charging the battery, it is estimated that the danger, and at any time to touch your power is not already already boiled eggs. 72w more than the 56w adapter 16w is to cope with this situation. So it is best not to use a small current instead of high current power supply
Q:Is the laptop power adapter hot?
Third, the power of the nominal voltage than my books the battery voltage is much higher, not an accident, right? First of all, to know is that the power supply to the books and the battery power supply to the notebook is different. Battery-powered, the battery output is pure DC, very clean, the battery voltage is neither possible nor need to design a high, lithium battery chemical properties determine a cell output voltage can only be about 3.6V, so Many batteries are used in three cascade way, 10.8V also became a very popular battery voltage. Some batteries are slightly larger than the integer value of 3.6V, such as 3.7V or 11.2V, etc., in fact, to protect the battery. Power supply, the situation is more complex, first of all need to add voltage to further regulation filter to ensure that the power performance is not very good in the case of stable work, the voltage regulator after the two parts of the city, all the way to the work of the power supply , The other way to the battery charge to the part of the power supply to the battery when the same power supply, and the part of the battery charge through the battery charge control circuit can be added to the battery, the control circuit can be very complex, so the power The voltage must be greater than the cell voltage to have sufficient capacity to supply the charge control circuit to the units. Finally the voltage actually added to the cell will never be the nominal voltage of your power supply. Rest assured.
Q:How to make the motor speed (control speed), can not use frequency
Do not use the variable frequency motor with the speed motor
Q:Is it possible to use a different laptop's power adapter?
For the power adapter, whether access to equipment, the following aspects of the measurement standards: Interface form The interface plug and socket used must be dimensioned. Voltage size The output voltage of the adapter is the same as the required voltage of the connected device (eg notebook). Inconsistencies may not be able to start or burn the device properly. Current or power The power of the adapter is greater than the maximum power required by the device. Power is not enough, may cause the voltage to drop, the adapter is hot, or burn the adapter. More than the above, the use of more power of the power adapter, while meeting the interface and voltage conditions, it can be replaced.
