Q: Which country invented the inverter?: Since 1960s, thyristor and its upgrade products have been widely used in power electronic devices. But its speed performance is far from meeting the needs. In 1968, the high-tech enterprises represented by Danfoss began to batch produce frequency converters and opened a new era of inverter industrialization.The beginning of 1970s, PWM VVVF (PWMVVVF) speed research get breakthrough, in 1980s after the microprocessor technology is perfect makes the algorithm easier to achieve.In the middle and late 1980s, VVVF converter technology in developed countries, such as America, Japan, Germany and Britain, was practical and the products were put into market and widely used. The earliest converters could have been bought by British and developed by British patent. However, the United States and Germany, with the advantages of electronic components production and electronic technology, high-end products quickly seize the market.Entered in twenty-first Century, the domestic inverter gradually rise, has gradually seize the high-end market. Shanghai and Shenzhen to become the forefront of domestic inverter development, emerged as Huichuan inverter, inverter, AMB inverter, frequency converters and a number of well-known domestic inverter. The AMB inverter was established in 1998, is one of China's first production of inverter manufacturers. Over the past decade, as the cornerstone to AMB rich cultural heritage, to support growth, enterprise quality system ISO9000 TUV earlier passed the certification, was awarded the "national high tech enterprise", has been appraised as "China user satisfaction of the ten domestic brands inverter".

Q: Where is the difference between soft starter and converter?: The high voltage soft starter must have a high performance control core that can handle the signal in a timely and rapid manner. Therefore, this control core usually uses high performance DSP chips instead of ordinary microcontroller cores of low voltage soft starter. Low voltage soft starter. The main circuit is composed of three sets of thyristor in reverse connection. But in the high-voltage soft starter, because of the shortage of the capacity of the single high voltage thyristor, it must be divided into several high voltage thyristors for partial pressure. However, the performance parameters of each thyristor are not exactly the same. The inconsistency of the thyristor parameters can cause the thyristor to break out of time, resulting in damage to the thyristor. Therefore, in the selection of thyristors, it is necessary to ensure that each phase of the thyristor parameters as consistent as possible, and each phase of the thyristor RC filter circuit element parameters as consistent as possible.

Q: What does "EPCU" mean in a frequency converter?: But look at your inverter has also been used for some time, if not before, and now appear, it is estimated that the hardware is broken, and manufacturers communicate maintenance!

Q: Why does the frequency change when the frequency converter regulates the frequency?: Main flux of motorM = U/ (4.44*f*N)In the upper model, the U is the stator voltage, that is, the output voltage of the inverter, f is the frequency, and N is the stator winding turn number.N is a constant.Obviously, when the frequency changes, if the voltage is constant, then the flux will change.The iron core of the motor is nonlinear, and when the flux changes, both too large (saturated) or too small (weak magnetic) is detrimental to the motor.Therefore, when changing the frequency, the voltage is changed, and the constant value of U/f is kept, so that the magnetic flux can be kept unchanged.

Q: How much is the motor 90KW and the frequency converter selected?Colleagues suggest 110W?The cost will be higherIs it okay to choose 90KW?: You refer to the type and parameters of the frequency changer to select.

Q: The difference between soft starter and converter: Soft start only in low voltage system, so called, high voltage motor is currently using more liquid resistance starter (cabinet), commonly known as "water resistance."". The function is almost the same, but the principle is different. The former is activated by thyristor controlled current limiting, and the latter is started by resistance voltage regulation and current limit.

Q: What does the RUN key on the inverter mean? How do you use it?: In general, when selecting panel operations (when the panel of the inverter is the control source of the inverter), it is the meaning of the "running" button. Press it, the converter will run, turn or reverse

Q: PT100 temperature patrol instrument, when the converter is not open, the measurement is normal. Once opened, it shows completely disorder, and sometimes there are puzzling characters. How can I solve this problem? Please enlighten master!: To clear the train of thought, in order to achieve the normal work of the temperature detector, it is impractical to test the inverter. So what we can do, basically, is shielding, filtering, grounding, and the like.

Q: What does "frequency" in household appliances mean?: The new inverter refrigerator not only the reduction of power consumption, realize mute, and the use of high-speed operation can achieve substantial rapid freezing; in the washing machine, used frequency variable speed control, improve washing performance, washing machine popular in addition to saving energy and silent, still ensure soft clothing washing and other aspects of the introduction of control new content;

Q: What is the over-current of the inverter?: External cause:?1, the motor load mutation caused by excessive impact, resulting in excessive flow.?2, the motor and motor cable phase or insulation damage to each other, resulting in short circuit turns to the ground, resulting in over-current.?3, over-current fault and motor leakage reactance, motor cable coupling reactance, so choose motor cable must be selected according to requirements.?4. Power factor correction capacitor or surge absorption device on the output side of inverter.?5. When the speed feedback signal is lost or abnormal, it will cause excessive flow, and check the encoder and its cable.
