Selection of inverter power

The system efficiency is equal to the product of the inverter efficiency and the motor efficiency. From the perspective of efficiency, the following points should be paid attention to when selecting the converter power:

1) the inverter power value and the motor power value is the most appropriate, to facilitate the inverter in high efficiency value operation. 

2) when the power classification of the inverter is different from that of the motor, the power of the inverter should be as close to the power of the motor as possible, but slightly greater than the power of the motor. 

3) when the motor is in frequent starting and braking work, or in heavy load starting and more frequent work, the converter of a higher level can be selected to make use of the inverter for long-term and safe operation. 

4) according to the test, the actual power of the motor does have surplus. It can be considered to choose a frequency converter with a power less than the motor's power. However, it is necessary to pay attention to whether the instantaneous peak current will cause overcurrent protection. 

5) when the power of the inverter is different from that of the motor, the setting of the energy saving program must be adjusted accordingly to achieve a higher energy saving effect .

Selection of inverter box structure

The box structure of frequency converter must adapt to the environmental conditions, that is, temperature, humidity, dust, ph, corrosive gas and other factors must be considered. The following types of structures are commonly available to users:

1) open IPOO type itself has no chassis, which is suitable for the screen, disk and frame installed in the electric control box or the electric room, especially when multiple frequency converters are used in one place, it is better to choose this type, but the environmental conditions are higher; 

2) closed type IP20 is suitable for general use, where there is a small amount of dust or a little temperature and humidity; 

3) sealed IP45 is suitable for poor industrial site conditions; 

4) closed type IP65 is suitable for poor environmental conditions with water, dust and certain corrosive gases.

Determination of frequency converter capacity

Reasonable capacity selection itself is a kind of energy-saving measures. According to the existing data and experience, there are three relatively simple methods:

1) determine the actual power of the motor. First of all, the actual power of the motor is measured to select the capacity of the inverter. 

2) formula method. When a frequency converter is used for more than one motor, it should be satisfied that the influence of starting current of at least one motor should be considered to avoid overcurrent trip of the frequency converter. 

3) motor rated current converter. 

Frequency converter capacity selection process, is actually a process the best match between the inverter and motor, relatively safe is the most common, also make the converter capacity is greater than or equal to the motor rated power, but want to consider the actual power of the motor in the actual match what differ with rated power, are usually selected equipment capacity is big, but the actual ability to small, so according to the actual power of the motor to select frequency converter is reasonable, avoid to choose the frequency converter is too large, increased investment. For the light load class, the frequency converter current should be generally selected according to 1.1n (N is the rated current of the motor), or according to the maximum motor power specified in the product by the manufacturer to match the rated value of the output power of the frequency converter.

The main power supply

1) power supply voltage and fluctuation. Special attention should be paid to the frequency converter low voltage protection setting value, because in practice, the possibility of low power grid voltage is greater. 

2) frequency fluctuation and harmonic interference of the main power supply. This interference will increase the heat loss of the converter system, resulting in increased noise and decreased output. 

3) the power consumption of the inverter and the motor when working. When designing the main power supply of the system, the power consumption factors of both should be taken into account.

The development direction

The substrate of power electronic devices has been transformed from Si to SiC, which makes the new components have the advantages of high voltage resistance, low power consumption and high temperature resistance. And the manufacture of small volume, large capacity of the drive device; Permanent magnet motors are also being developed. With the rapid popularization of IT technology, the technology related to frequency converter develops rapidly, and IT will mainly develop to the following aspects in the future:

Network intelligence

The intelligent frequency converter does not need to set many parameters when it is used. It has the function of fault self-diagnosis, high stability, high reliability and practicability. The Internet can realize the linkage of many frequency converters, and even the integrated management control system of frequency converters based on the factory.

Specialization and integration

Inverter manufacturing specialization, can make the inverter in a field of stronger performance, such as fan, water pump inverter, elevator inverter, special frequency converter for lifting machinery, special frequency converter for tension control. In addition, the frequency converter has the trend of integration with the motor, make the frequency converter become a part of the motor, can make the volume smaller, more convenient control. 

Energy conservation and environmental protection

Protecting the environment and making "green" products are new ideas of human beings. The energy saving and the low public hazard in the energy conversion process of inverter should be taken into consideration in the electric drive device, so as to reduce the noise and power harmonic pollution to a minimum degree. 

Adapt to new energy

Fuel cells powered by solar and wind power are now emerging as a cheap alternative. The biggest characteristic of these power generation equipment is the capacity is small and dispersive, the frequency converter in the future will have to adapt to such new energy, both high efficiency, and low consumption. At present, power electronics technology, microelectronics technology and modern control technology are developing at an amazing speed, and the technology of variable frequency speed regulating drive is also making rapid progress, which is mainly reflected in the large capacity of ac speed regulating device, the high performance and multi-function of frequency converter, the miniaturization of structure and so on. 

 Variable frequency Drive (VFD) is the principle of applying frequency conversion technology and microelectronics technology to control the ac motor's power control equipment by changing the frequency of the motor's working power supply. The power supply can be divided into ac power supply and dc power supply. The general dc power supply is mostly obtained by ac power supply through transformer transformer transformer, rectifying and filtering. Ac power supply in the use of power supply in people accounted for about 95% of the total power supply.

There are two methods of frequency conversion speed regulation: one is ac - dc - ac frequency conversion, suitable for high speed small capacity motor; The other is ac - ac frequency conversion. Suitable for low speed and large capacity drag system.

Variable frequency air conditioners can be classified into 3A and 3D variable frequency air conditioners according to the types of indoor fan motors, outdoor fans and compressors. For the indoor, outdoor fans and frequency conversion compressor are AC (AC) form of variable frequency air conditioner, commonly known as 3A variable frequency air conditioner; And for indoor, outdoor fans and variable frequency compressor are three - phase dc brushless motor (DCBLM) form variable frequency air conditioner, generally called 3D variable frequency air conditioner. The latter price is much higher than the former, only the material cost is higher than the same power of the 3A variable frequency air conditioner nearly 300 yuan, and the development is more difficult, the air conditioning system and controller with high complexity.
