- Q:Do you need to rectify before switching?
- Need to rectify.
The inverter is actually an inverter, which first turns the alternating current into direct current, then switches the DC power with the electronic components, changes to alternating current, and the general-purpose inverter is equipped with a thyristor and an adjustable frequency The frequency is adjustable in a certain range, and it is used to control the number of revolutions of the motor, so that the number of revolutions can be adjusted within a certain range.The frequency converter is widely used in the speed regulation of AC motor. Technology development direction, with the development of power electronics technology, AC frequency conversion technology from theory to practice gradually mature. Inverter not only smooth speed, large range, high efficiency, start current is small, smooth operation, and energy saving effect is obvious. Therefore, the exchange frequency control has gradually replaced the traditional traditional slip speed, variable speed control, DC speed control system, more and more widely used in metallurgy, textile, printing and dyeing, smoke machine production lines and buildings, Water supply and other fields. Generally divided into rectifier circuit, flat wave circuit, control circuit, inverter circuit, and so on several major parts.
- Q:Laptop power adapter is used to do what
- Simply put the transfer into DC
China's electricity is 220V AC, and the notebook is a direct current, the need for adapter to rectify, filter, regulator, and finally we need to form a direct current
- Q:Delta VFD-A frequency converter motor number of poles set
- Variable frequency
Drive, VFD) is the application of frequency conversion technology and microelectronics technology, by changing the motor operating frequency mode to control the AC motor power control equipment. The inverter is mainly rectified (AC variable DC), filter
Wave, inverter (DC variable AC), the braking unit, the drive unit, the detection unit micro-processing unit and so on. The inverter is used to adjust the voltage and frequency of the output power by breaking the internal IGBT.
- Q:Variable frequency pump pressure in the very low flow instability, why?
- . If you want to stabilize the pressure, you must adjust the pipeline characteristic curve is the work point to enhance, so that you can both stabilize the pressure and adjust the flow.
- Q:Motor 2 pole and 4 pole in the inverter with what set to show
- There are parameters for the number of motor poles / pole pairs or the rated speed of the motor in the inverter parameters
- Q:Can the inverter stop intermittently during operation? If so, how to connect and set up
- Look at your inverter manual, because the inverter is not a simple wiring can run, first of all have to know that a few are external terminals (inverter input terminals),
- Q:First reduce the frequency of about one-third of the test, not the case, then appropriate adjustments!
- In short, then connected to the bk-dk electrical appliances, is a resistor for the discharge effect
- Q:Laptop power adapter repair how much money
- Dell laptop warranty 36 months of hardware include: CPU, memory. Warranty 24 months of hardware include: motherboard, graphics card, LCD screen, hard drive, power adapter, keyboard, mouse module. Warranty 12 months of hardware include: LCD accessories, CD-ROM, DVD, CDR / W, floppy drive, Modem card, network card, camera and other functional modules and components. Battery warranty for 3 months. Random disc, random gift of micro-computer products such as warranty 3 months. The
- Q:How to view your own laptop power adapter is how much tile?
- There are signs on the power adapter, you look for sticky paper to write the voltage and current power. If there is no write power, the direct voltage multiplied by the current is the maximum power.
- Q:The relationship between the power supply of the notebook and the battery
- 2, when the laptop turns on the power adapter, and the battery power is low, the charging circuit detects the battery power is lower than the set value, the power adapter will side of the host power supply, while the battery charge. After the charge is restored, it is restored to the power supply state directly from the adapter.
Therefore, the relationship between the power supply of the notebook and the battery is that the battery is charged by the power adapter when the battery level is below the set value.
