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: The inverter control power is also the same, the pole is not the same as the motor 6 or 4 pole can be used?
- Can be used, their rated current is not the same, the need to use the inverter over-current overload protection and other parameters for the corresponding changes.
- 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: Laptop power adapter current is not the same alternative?
- The adapter is the voltage source, the actual output current depends on the size of the load resistance,
- Q: What is the motor series parameter setting of the inverter? If it is with the spindle,
- Ordinary inverter standard drive is a 4-pole motor, the greater the number of poles of the motor, the greater the rated current, the motor pole number is the frequency converter when the self-learning automatically set, in the vector control must be self-learning
- Q: I have a 5.5 kilowatts of 4-pole motor, want to pass through the inverter, slow down to 130 per minute use, eliminating the need for speed,
- Power will drop, down to the original one-tenth
- Q: What are the differences and links between the soft starters and the frequency converters, and their respective principles and uses?
- Soft starters and frequency converters are two completely different uses of the product. The frequency converter is used for the need for speed control where the output not only changes the voltage but also changes the frequency; the soft starter is actually a voltage regulator for the motor to start when the output only changes the voltage and does not change the frequency. The frequency converter has all the soft starter functions, but its price is much more expensive than the soft starter, the structure is much more complex. Soft starter (soft starter) is a set of motor soft start, soft stop, light load energy saving and a variety of protection functions in one of the new motor control device, known as the Soft Starter abroad. The softener uses a three-phase anti-parallel thyristor as a voltage regulator, which connects it between the power supply and the motor stator. This circuit, such as three-phase full-bridge rectifier circuit. When using the soft starter to start the motor, the output voltage of the thyristor gradually increases, the motor gradually accelerates until the thyristor is fully conductive, the motor works at the mechanical characteristics of the rated voltage, smooth start, reduce the starting current and avoid starting the overcurrent trip. When the motor reaches the rated speed, the start-up process ends, the soft starter automatically uses the bypass contactor to replace the completed thyristor, providing the rated voltage for the normal operation of the motor to reduce the heat loss of the thyristor and prolong the service life of the soft starter , To improve its efficiency, but also to avoid the harmonic pollution to the grid. Soft starter also provides soft stop function, soft stop and soft start the process of reverse, the voltage gradually reduced, the number of revolutions gradually reduced to zero, to avoid free-wheeling caused by the impact of torque. How the frequency converter works
- Q: Huichuan frequency converter drag a 4-kilowatt four-pole motor to change the six pole can?
- can. Re-enter the new motor parameters in the drive.Inverter motor power to 4KW, speed 980 can!
- Q: Short-term short-circuit converter DC link positive and negative will damage the inverter?
- This short circuit may not necessarily line, the inverter fan has three, one is no speed line, two are pulse, three are switching signal (this is very little, I only encountered several),
- Q: Three motors, if coupled with the governor speed, is it necessary to add the inverter?
- ?Fifth, the hydraulic coupler speed: hydraulic coupler is a hydraulic transmission device, generally composed of the pump wheel and turbine, when the pump wheel in the prime mover driven under the rotation, in which the liquid is driven by the blade and rotation, in the Under the action of centrifugal force along the outer ring of the pump wheel into the turbine, in the same turn to the turbine blades to thrust, to drive the production machinery operation. Through different hydraulic (lubricants and turbines) to achieve speed.
- Q: What is the output voltage of the laptop power adapter?
- 16V to 20V, different brands may be different, 19V, 20V more.
