Q:What is the output voltage of the laptop power adapter?
Generally have 19V of the common friends, I was 19V
Q:What is the application of variable frequency speed control?
In the second half of the 20th century, the power electronic devices from the SCR (thyristor), GTO (gate can be turned off thyristor), BJT (bipolar power transistor), MOSFET (metal oxide field effect transistor), SIT (electrostatic induction transistor ), SIT (Electrostatic Inductive Thyristor), MGT (MOS Control Transistor), MCT (MOS Control Gate) to today's IGBT (Insulated Gate Bipolar Transistor), HVIGBT (High Voltage Insulated Gate Bipolar Thyristor), Device To promote the continuous development of power conversion technology. Since the 1970s, pulse width modulation variable frequency (PWM-VVVF) speed control research has aroused people's attention. In the 1980s, the PWM model optimization problem, which was the core of the frequency conversion technology, attracted people's interest and made many optimization modes, in which the saddle-wave PWM mode was the best. The 20th century, the late half of the 1980s, the United States, Japan, Germany, Britain and other developed countries VVVF inverter has been put into the market and widely used.
Q:Laptop computer about electricity no electricity, is the power adapter problem?
To judge this is very simple: 1. The computer is in the battery state to see if it works properly. If it does not work, the battery has a problem 2. Remove the battery from the computer with a power adapter to see if it is working properly. If not, there is a problem with the power adapter 3. If the two states can work that is the computer charge management part of the poor contact and other issues.
Q:What is the IGBT? Our inverter IGBT fried,
Popular point is a switch, give him the signal to continue in accordance with a certain order switch, the DC through the switch into a change in the exchange of alternating current, different frequency.
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:How many types of CVT are classified?
CVT (Continuously Variable Transmission) technology that is continuously variable technology, which uses the belt and the working diameter of the main and driven wheel to match the power to transfer, you can achieve a continuous change in transmission ratio, resulting in transmission and engine conditions of the most Good match
Q:18: 5 kilowatts bipolar multi-pole pump motor with inverter
With a 18.5kw inverter can ah such as ABBACS510 series
Q:Laptop adapter heat
Therefore, in the design and production of switching power supply, we must choose high temperature components. Of course, be sure to control the temperature of the power supply within the allowable range of the application environment. First, the conversion efficiency should be designed as high as possible, and secondly, to use the pressure drop is small, low loss of switching components, the third is to be thermal design, cooling area to be as large as possible, more than 100W switching power supply Should have a metal perforated shell, or add a cooling fan. The current notebook power adapter power is generally around sixty or seventy W, the use of high temperature plastic fire sealed package, the internal heat generated by the plastic shell mainly distributed out. Therefore, the power adapter surface temperature is still quite high, the maximum temperature or even reach about 70 degrees! Think of the inside of the adapter, it is not like the fire! So, when you use the laptop, try to place the power adapter in a better place to ventilate heat, do not put books and the like on the power above. As for the kind of hot feeling, do not have to worry about is the power, not angry strange!
Q:ASUS and dell notebook power adapter can be universal?
I can not remember to insert into the ah. The Looks like DELL that interface is very special
Q:Laptop power adapter bad what is the phenomenon?
If you unplug the power adapter is good, then your adapter has a problem, you are the original adapter, I encountered the imitation of the adapter has this problem,
