变频调速技术的飞速发展为变频器性能的提高提供了技术保障,而环保和节能的客观需要,又为变频器在生产和生活的各个领域的应用提供了发展空间,随着国民经济的发展,小容量变频器越来越不能满足现代化生产和生活的需要、大容量变频器正在调整铁道运输系统、船舶推进系统、轧钢系统、大型风机、压缩机调整系统等领域展示了其良好的应用前景,但是大容量变频器和小容量相比,还有许多关键技术需要进一步解决和完善。
The rapid development of inverter technology provides technical support for the improvement of inverter performance, while the objective requirements of environmental protection and energy saving also provide space for the application of inverter in various fields of production and living. With the development of national economy , Small-capacity inverters are increasingly unable to meet the needs of modern production and living. The large-capacity inverters are showing good application prospects in the fields of railway transportation systems, ship propulsion systems, rolling systems, large fans and compressor adjustment systems However, there are many key technologies that need to be further solved and improved in comparison with the small capacity of a large-capacity inverter.
