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

Power module
The inverter section within the drive is of a modular designusing identical power modules connected in series to create
the required medium voltage output. Each power moduleuses a well-proven low-voltage IGTB-based single-phase H-bridge architecture for added reliability, economy and ease of replacement.The standard power module for two-quadrant control
(bi-directional motor speed control without braking) uses a diode rectifier at the front end. An optional power module is available which uses an IGBT-based rectifier to allow power to be returned to the supply allowing full four-quadrant operation (motoring and braking in both directions). This
“Active Front End” is modulated to draw sinusoidal current from the supply and control the input power factor to unity. The AFE version can also be used to continuously return power to the network for renewable energy generation applications such as for wind and tidal turbines.
- Q: What is the difference between the electronic governor and the frequency converter on the motor speed regulation?
- Electronic governor is the use of control thyristor conduction angle to change the motor supply voltage, the motor characteristics of the curve down to change the speed of asynchronous motor. Its characteristics are as follows: the motor speed adjustment range is small, low speed when the motor load capacity is poor, the speed decreases, the motor torque decreases, not applicable with constant load, when the speed is low, prone to stall phenomenon; Applicable to fan load. Inverter speed is to change the frequency of the motor to achieve the AC asynchronous motor speed adjustment, speed adjustment balance, the motor load characteristics do not change with the speed change, suitable for load adjustment and constant torque adjustment. Excellent performance, but the cost is higher.
- Q: Motor 2 pole and 4 pole in the inverter with what set to show
- Motor parameters, there must be a parameter "motor pole" of the bar.
- Q: What are the types of power adapter used in notebooks?
- Notebook function is limited, such as power requirements of only 50-70 watts (W). In recent years, power requirements have risen above 100 W, but the expectations for weight and size have not improved accordingly. In addition, the need to meet the low standby power performance in the specification, external power (EPS) efficiency requirements and IEC1000-3-2 harmonic power requirements above 75 W make this challenge more difficult to deal with. This article explores new trends that enable power supply manufacturers to address these challenges and provide alternative solutions to choose from.
- Q: Motor nameplate on the standard 2P, I set the number of motor pole in the inverter, is set 2 or 4 pole?
- n the motor pole, an Antarctic (S pole), an Arctic (N pole), calculate a pair of poles, the number of pole pairs is how many such "pairs" (S pole + N pole). 2 pole motor --- pole pairs 1 = P = 1,4 pole motor --- pole pairs 2 = P = 2, and so on.
- Q: Delta VFD-F frequency converter how to adjust the number of poles
- Go to the official website of some inside a detailed description
- Q: What is the base blockade in the drive?
- After the base is blocked, the power tube is fully closed to protect the power tube.
- Q: Can the four motors be tuned to 2900 rpm?
- Will be affected, under normal circumstances overclocking is possible, but speed is not possible.
- Q: What is the maximum speed adjustable for a 4-stage motor with a rated frequency of 50Hz / 60Hz?
- Generally transferred to 60Hz, about 1800 rpm, although the maximum speed when the inverter speed adjustable to 135Hz, but the motor does not work. Bearing first to consider.
- Q: Three sets of batteries (540V) DC power supply U / f inverter.
- It is estimated that the battery should be string - and - series connection method, and then rectifier part of the converter (which may also be caused by the switch) is actually a series of diodes in series, positive and negative after the reverse is actually the battery is Negative shorts, resulting in burning, as to burn only one of the group of a few cells, it should be string - and - string and that group, because the parallel to bear it double voltage.
- Q: 90KW inverter start 90KW, 4-pole motor and 6-pole motor j What is the difference? The inverter can be used for it?
- The number of poles of the motor and the inverter is not very different, the difference is the motor speed is different
