Introduction
In the RMVC 5100 converter, the medium voltage output isconstructed by connecting the outputs of single-phase
low-voltage IGBT-based inverters in series, with an equal number per phase. Each individual single-phase inverter power module is powered by an internal rectifier, itself supplied from separate phase-displaced secondary
windings of the integrated transformer. An inherent feature of this technology is that a high pulse number rectifier is created resulting in a significant reduction of input current harmonic distortion. In the example shown below for a 6kV output, the diode rectifier is 30-pulse. The input Power Factor is also high at a minimum of 0.95 regardless of speed and power. The PWM switching strategy ensures that sinusoidal current is supplied to the motor. The low levels of harmonic current in the motor ensure that both motor heating and shaft torque pulsations transmitted to the coupling and load are minimised. Use of the multi-level PWM topology also results in areduced size of voltage steps imposed on to the motor and cable insulation systems compared to 2 or 3-level inverters.The dV/dt is less than 1,000V/μs.

FAQ
1.what kind of load the frequency inverter used for?
2.Please provide specific motor parameters ?
3.Application Environment
4.if need special internet port?
- Q:How does the variable frequency motor output torque at very low frequencies?
- 50hz the following frequency, u constant, current and frequency is proportional to the frequency down the output current is also down, and torque and current is proportional to the natural torque is small
- Q:Delta inverter reported CE4 reasons? Casually asked how many kinds of CE under a total
- If the Delta C2000_M is the Modbus drive can not handle Not to the official website under the manual
- Q:Laptop power adapter leakage
- You feel, or do not feel is to take the amount of pen? If the feeling after it, then for a, if the amount of pen, then hand touched, it should not be bright. That is a induction, is Virtual electricity, it does not matter.
- Q:What is the difference when using inverter frequency conversion ordinary motor and variable frequency inverter motor
- First of all you have to understand the difference between variable frequency motor and ordinary asynchronous motor. 1, inverter motor cooling fan is not connected with the motor spindle, is independent, the fan rotation from the motor speed, to ensure that the motor cooling.
- Q:Quartet of the TA, TC terminals have positive and negative?
- There is no positive and negative, this is the relay output
- Q:The Schneider inverter reports the nlp command
- 1, the inverter control circuit with an external 24V power supply, the main circuit did not power 2, PO and PA between the short film can not cause this failure.
- 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:How to choose the inverter
- and you need to know how The use of frequency converter, as well as voltage 380, are fixed, and the frequency can be changed
- Q:On the laptop power adapter problem
- Can be simply calculated; 19 * 4.74 = 90.06 90W 19 * 3.42 = 64.98 65W Obviously, the second is a virtual standard, can not be used It is not enough power, ranging from the adapter burned, while the motherboard is like other notebook hardware damage, unpredictable. The adapter is likely to burn after the high and low voltage to the notebook board burned the situation more common. My notebook is dell original 4.62A, when playing the game are very hot.
- Q:Master Hello a machine requires 500 speed matching 6-pole motor frequency converter transferred to about 28HZ
- If the machine needs the same speed, constant 500r / min This can be directly with the motor, remove the inverter, but also save costs, while the motor at 50Hz, the maximum power point of rated power. Output torque is the most stable point. The pulley diameter becomes smaller and the reduction ratio increases, and the torque required by the motor becomes smaller, which is advantageous for the motor. 960/500 = 1.92, that is to say the motor pulley compared to the original tune less 1.92 times
