Q: What's the use of switching frequency of converter?: The chopper device also has switching life, the higher the switching frequency, the shorter the life of the inverter, and will reduce the inverter output current and power. The smaller the chopping frequency, the higher harmonic content and the more serious harmonic pollution.

Q: High-voltage converterGeneral inverterPump frequency converterEngineering frequency converterCould you tell me some frequency converter according to the class?: Frequency converter classification method can have many kinds, according to the technical characteristics of the points, according to the voltage level to be divided, and also according to the application characteristics of the points. It's hard to make a brief statement. The four types of frequency converters you list are based on different classification methods. The above is according to the technical classification to tell you, more complex, I will not say more.

Q: Knowledge, principle and operation method of frequency converter.: The three major parts of the working principle of frequency converter:This is how the inverter works, but how does it work? Mainly composed of three components. (1) convert the power frequency power to the rectifier of the DC power: it transforms the power frequency power into the DC power supply. A reversible converter can also be constructed using two sets of transistor converters, which can be regenerated for their reversible power direction. (2) absorption in the converter and inverter voltage generated by the pulsating "flat wave circuit" in the rectifier DC voltage is rectified, ripple voltage with power frequency 6 times, in addition the pulsating current generated by the inverter to the DC voltage fluctuation. (3) the DC power conversion for AC power rectifier with "inverter": instead, the inverter is DC power converter for AC power required frequency, to the time the 6 switch off, you can get 3 phase AC output.

Q: The frequency converter is in use suddenly the speed reduces, then the debugging is out of control, how to do?: The average DC voltage Ud=1.35U line =513V is calculated by the 380V line voltage. When the overvoltage occurs, the energy storage capacitor on the DC bus will be charged, and when the voltage rises to about 700V, due to different models, the converter will protect the voltage. There are two main causes of over voltage: over voltage and over voltage.

Q: What's the function of this brake unit?: When the motor is fast stopping, the motor will feedback the energy to the converter, causing the DC bus voltage to rise or even damage the IGBT. Therefore, it is necessary to use the braking unit to save the part of the energy to protect the converter.Inverter braking a lot, can refer to:

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: Why does harmonic generator produce harmonic? What's his working principle?: Harmonic generation mechanism of inverter inputThe main circuit of inverter is composed of AC-DC-AC, external input 380V/50Hz power supply through the three-phase bridge rectifier, a DC voltage, AC voltage by the capacitor filter and high power transistor switching element for variable frequency inverter. In the rectifying circuit, the input current waveform is a rectangular wave irregular waveform, according to Fu Liye series is decomposed into fundamental and harmonics, the harmonic frequency is usually 6N + 1 harmonic, the harmonic interference input power supply system. If the reactance of the supply side is sufficiently small and the commutation overlap angle can be neglected, then the n order harmonic is the 1/n of the fundamental current.

Q: What are the basis of the frequency converter to choose?: According to the applied industry.The application of inverter industry RGB field is widely used, the main products are: SAJ-S simple ultra small, SAJ-M mini, SAJ-G universal, SAJ-F type, SAJ-P type wind pump, SAJ-Y injection molding machine type, SAJ-Z type, heavy machine industry, naked personalized products, high performance vector inverter S350.

Q: What is the working principle of a three phase AC asynchronous motor inverter?: I. operating temperature. The internal electronic components of high power, extremely easy to be influenced by the working temperature of the product, the general requirements for 0 ~ 55 degrees, but in order to ensure the safe and reliable work, use should be considered under the best control in 40 DEG C. In the control box, the inverter shall be installed on the upper part of the box, and strictly comply with the installation requirements in the product specification. Absolutely no heating element or easy heating element shall be installed on the bottom of the converter.

Q: Delta inverter fault output which parameter is set?: Overvoltage overvoltage fault of inverter DC bus voltage on the tributaries. Under normal circumstances, the average DC inverter three-phase full wave rectifier after. If 380V line voltage calculation, the average DC voltage Ud= = 513V. 1.35 U line in the overvoltage occurs when the DC bus capacitor will be when the charging voltage to about 760V, inverter over-voltage protection action. Therefore, inverter, have a normal range of working voltage, when the voltage of the inverter is likely to damage more than this range, there are two types of common overvoltage.
