Perfect Power Output Section
The HIVERT general MV VFD adopts the power cells connected in series and voltage overlapping method (i.e. Power cells multi-level cascade technology), it can output the perfect PWM sinusoidal waveform (see Figure 2 and Figure 3). It has the following advantages:
1. No need for the additional output filter
2. Directly driving general synchronous or asynchronous motor
3. No de-rating operation on the motor
4. No dV/dt stress on the insulation of motor and cables
5. No torque ripple, extending service life of motors and mechanism
6. No cable length restriction within the acceptable voltage drop.
The general MV VFD has the following protection functions and features:
Overload and over-current
Phase loss and grounding
Over voltage
Overheat
Current limit
Redundant control power supply
Cell Bypass (optional)
Cabinet door alarm
Phase-Lock function
Synchronous Switching between VFD and Grid system

- Q:How is the notebook with a power adapter?
- Refer to the following factors when purchasing: Choose the brand: The principle is to choose the same type with the brand, if not, it can only find other brands. Now online to sell a lot of notebook power adapter are cut corners of the substandard products, the normal use of what should be no problem, once the accident will burn your laptop, save dozens of pieces but burn thousands of pieces of notebook worth the candle. (Such as the actual only 19V3.42A, but the standard 19V4.74A, this will lead to a very slow charge, and even damage the battery and laptop computers. There are some protection removed, this more horrible, there Accidentally burn the laptop.
- Q:How to choose the right inverter?
- 1, constant power load During the operation of the load device, the power remains constant. Such as machine tools, cutting machines, paper machines and so on. For example: a marble cutting machine frequency conversion system, is a constant power load, load inertia, inverter selection configuration A power with the G-type machine, plus the braking unit and braking resistor.
- Q:Can the laptop power adapter be generic?
- Output voltage, current, interface can be used as well.
- Q:My laptop can not use the power adapter, and can only use the battery, how is it ah,
- 1, laptop power adapter can not be used, first check the power outlet, plug, cable has no virtual state, if you can tell the normal equipment damage. Should be repaired. 2, the laptop battery must be charged through the power adapter or directly for the computer power, the power adapter is not missing, if you have experience can turn on the power adapter to see if the fuse is broken, try to update the fuse can be restored. If the integrated circuit is damaged, only updated.
- Q:Siemens g120 inverter torque limit what is the meaning
- For example, you have 100kg of power, but you can send the power and you lift the weight of the object, if the object weight of 10kg, you can only use 10kg of power.
- Q:400w 6-pole motor should be equipped with much of the inverter?
- 0.75KW just fine, neither waste the inverter resources, but also to meet the occasional overload. And 0.75KW inverter is the standard model.
- Q:Laptop power supply 20V 3.5A can use 20V 4.5A power adapter Mody, what impact?
- It's ok. As long as the voltage is appropriate on the line. Current value refers to the maximum current that can be output. How much depends on your computer. Or, with a big no harm, can only be better, if you can use a small, but a little longer charging time.
- Q:Three-phase asynchronous AC motor speed control method
- Third, cascade speed control method Cascade speed regulation refers to the winding motor in the rotor loop into the adjustable additional potential to change the motor slip, to speed control purposes. Most of the slip power is absorbed by the additional potential in series, and the additional device is used to return the absorbed slip power to the grid or to convert the energy. According to the slip power absorption and utilization, cascade speed can be divided into motor cascade speed, mechanical cascade speed control and thyristor cascade speed form, the use of thyristor cascade speed, which features: Can be transferred in the speed of the process of slip loss back to the grid or production machinery, the higher efficiency; Device capacity and speed range is proportional to the investment province, for the speed range of 70% -90% of the rated speed of production machinery; Speed ??control device failure can switch to full speed operation, to avoid shutdown; Thyristor cascade speed power factor is low, the greater the impact of harmonics. This method is suitable for use in wind turbines, water pumps and rolling mills, mine hoists, extruders.
- Q:What is the IGBT? Our inverter IGBT fried,
- Basically change the voltage, the voltage changes in accordance with the different frequencies, so that change the speed.
- Q:380V motor addition to the inverter, but also how to change its speed?
- 1. Change the number of pole pairs of the motor. (Multi-pole motor use) 2. Use the frequency converter to change the frequency
