With the rapid development of inverter industry in China, the development of high voltage frequency conversion speed control technology has the following points:
Inverter in the AC variable frequency speed control technology is a form of hybrid electrical, mechanical and electrical integration and comprehensive technology, can better from this area to handle the huge power conversion form, and in this collection and processing of information transmission, transformation and there is a certain effect, so it will surely success rate and most of the two forms, according to this comparison, so the effect is largely rotation, to consider the situation from the aspects of technology.
The former to solve the problem of high voltage and high current technology, the latter to solve the problem of software and hardware control. Its main performance is:
1, high voltage inverter will be toward the large power, miniaturization, light of the direction of development.
2, high voltage inverter will be directly to the high voltage and multiple stack (device series and elements in series) in two directions.
3, higher voltage, a new type of power semiconductor devices will be applied in the high voltage inverter.
4, at this stage, IGBT, IGCT, SGCT will still play a major role, GTO, SCR will exit the inverter market.
5, the speed sensorless vector control, flux control and direct torque control technology applications will tend to mature.
6, full digital, automatic: parameter self setting technology; process self optimization technology; fault self diagnosis technology.
7, the application of 32 MCU, DSP and ASIC devices, to achieve high precision inverter, multi function.
8, the relevant supporting industries are moving toward specialization, scale development, social division of labor will be more obvious.
From this eight points will be able to better understand the effect of the transducer, and the significance of expression also has a great effect, so as to better experience this effect.
