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

- Q: Is the laptop power adapter high temperature normal? Is there anything else?
- Normal, my power adapter is also very hot, generally ignore
- Q: Laptop adapter
- This principle is not, try, look at how the charge situation, if you can charge, can be filled, just a long time, to no harm However, the heat may be high, long-term so, there is a risk
- Q: Can the laptop power adapter be generic?
- Not common. Different computer adapter interface is not the same, and the voltage, current is not the same. If just the same, you can use, the voltage can also be used.
- Q: How does the variable frequency motor output torque at very low frequencies?
- 1, to improve the slip of the inverter compensation coefficient 2, to improve the continuous lifting coefficient of the inverter, but the coefficient is too high there will be overcurrent. 3, with no sensor vector control can increase the motor output torque or encoder with the vector control can make the motor at low frequency to achieve the rated output torque.
- Q: How to view your own laptop power adapter is how much tile?
- 1, the power adapter has a logo, you can find their own look, close to the paper or direct letterpress printed with the voltage, current and power. If there is no write power, the direct voltage multiplied by the current is the maximum power. 2, if the power adapter only identifies the output voltage is 20V, the output current is 4.5A, then we formula W (power) = V (voltage) xI (current) to calculate. Calculate the formula with a power to know the output power is 20 × 4.5 = 90W.
- Q: The notebook power adapter flashes
- It seems you are still a novice ~ know the output voltage with the current is not ~ know the words to dig treasure shop name marked (days and along the power adapter) to find it ~ you have to ~ the price will not be expensive ~ I am in the days of business with the company Repair ~ ~
- Q: What is the difference between AC and DC frequency converters?
- Advantages and disadvantages: Advantages: inverter air conditioner with variable frequency power supply, inverter compressor, electronic expansion valve and microcomputer technology, the organic combination of air conditioning to further improve the performance, the use of room temperature fluctuations, better comfort, the better Power supply voltage fluctuation is not sensitive, the compressor starts, the general non-stop, cooling capacity in the range of 35% to 117% change, to avoid the frequent open air-conditioning, to extend the life of the compressor, while efficient, Features. Disadvantages: the price is more expensive, compared with ordinary air conditioning, about 1/3 to 1/4 of the price, at the same time, because the inverter air conditioner control system and frequency conversion system is more complex, higher requirements for components, compared to ordinary air conditioning , Inverter air conditioner failure rate is high, and, due to the use of frequency conversion technology, at the same time, will produce harmonic pollution. What is DC inverter air conditioner? DC inverter air conditioner is relative to the AC inverter air conditioner, in fact, its name is not correct, because the DC and no frequency, it is by changing the DC voltage to adjust the compressor speed, thus changing the air conditioning cooling capacity, It can only be said to be a DC variable speed air conditioning, not strictly in the sense of inverter air conditioner.
- Q: 18: 5 kilowatts bipolar multi-pole pump motor with inverter
- Under normal circumstances, with 15KW inverter on it.
- Q: How to make the motor speed (control speed), can not use frequency
- In general, the torque generated by the motor is reduced with decreasing frequency (decrease in speed), and the reduced actual data is given in some frequency converter manuals. By using the flux vector control of the inverter, will improve the motor at low speed torque, even in the low speed area motor can also output enough torque. When the frequency converter to speed up to 60Hz frequency, the motor output torque will reduce the normal motor is designed to 50Hz (60Hz) voltage, the rated torque is given in this voltage range. So the rated frequency under the speed is called constant torque speed, the inverter output frequency is greater than 50Hz frequency, the motor torque to be inversely proportional to the frequency of the relationship between the decline. When the motor is running at a frequency greater than 60 Hz, the magnitude of the motor load must be taken into account to prevent the motor output torque from being insufficient. For example, when the torque generated by the motor at 100 Hz is about to be reduced to about 50 Hz, the torque is generated. So the rated frequency above the speed is called constant power speed.
- 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.
