我国高压变频器的发展

The Development of High Voltage Converter in China

介绍了高压变频器的主电路拓扑结构和控制技术的发展概况，随着电力电子器件和现代控制技术以及计算机技术的发展，高压变频器的主电路拓扑结构和控制技术都得到了快速发展。在“十一五”期间，对高压大容量电机进行节能改造、建设节约型社会意义重大。要加速对高压变频器的主电路拓扑结构和控制技术的研发、创新，开发具有自主知识产权的高性能高压变频器，以推动我国高压变频器的发展。

The article introduces the development of the main circuit topology structure and control technology of high- voltage converter. With the development of the power electric and modem control technology as well as computer, the main circuit topology structure and control technology of high-voltage converter have been developed quickly. In the ill^th Five-Year Plani the meaning is very importance for that the high-voltage motors have been reformed saving energy and building economization society. We have to increase the speed of researching and innovating the main circuit topology structure and control technology of high-voltage converter, developing the high performance high-voltage converter in order to promote the development of high-voltage converter in our country.
