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

- Q:Can the inverter be used to control the speed of the DC motor?
- The inverter can be used to control the speed of the DC motor. Inverter control DC motor is to control the DC motor. Inverter is the application of frequency conversion technology and microelectronics technology to change the AC power frequency and effective voltage power control equipment. The frequency converter is usually used to control the AC motor. Inverter at work can change the AC power frequency and effective voltage, another point of view, is the inverter in the control output (injected into the controlled device) AC frequency, but also control the output of the effective power. A DC motor is a rotating electric machine that converts DC power into mechanical energy. DC motor coil in the current must be in accordance with certain changes (commutation) can be rotated, according to the principle of commutation DC motor can be divided into brush and brushless motor two categories.
- Q:Is the motor having a variable frequency motor and a variable voltage motor?
- According to the way to start talking about a variable frequency motor and variable voltage motor
- 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:Is the laptop power adapter AC and DC?
- Most laptop power adapters can be used for 100 ~ 240V AC (50 / 60Hz). Basically, most of the notebook computers are external power supply, with a power cord and the host connection, which can reduce the size and weight of the host, only a very small number of models built in the host power.
- Q:The relationship between the power supply of the notebook and the battery
- The relationship between the laptop power adapter and the battery should not be called a power supply relationship, both of which are devices that power the notebook host. The basic relationship between the power adapter, the battery, and the host is as follows:
- Q:What is the adapter?
- An adapter is a physical device that allows a hardware or electronic interface to interface with another hardware or electronic interface (adapt and without any loss).
- Q:Computer frequency changer to do cd frequency changer how points positive and negative
- Two identical capacitors in series, the capacity is half of the original, the two capacitors in parallel after the same capacity doubled.
- Q:Three-phase motor, quadrupole asynchronous motor to 15rpm, the inverter output how many volt voltage? The 4 V
- The voltage is basically the same, the inverter changes the frequency of the power supply, not the voltage.
- Q:Why G120 inverter to be equipped with 4-pole motor?
- I add point with the premise of the inverter is to understand the mechanical load characteristics (or process, etc.), can the parameters set.
- Q:What is the common COM point of the PLC and the inverter? Is it positive?
- Plc is divided into two kinds of transistor output and relay output, com side may be connected to the high level may also be connected to the low level, the general input com port then low, the output port com mouth high, specifically what to take See the data sheet. Inverter is the same, the inverter has 24v com side and 10v com side, can not be connected together, com side generally low.
