电力变换和控制技术导论

电力的开发和应用是现代社会经济发展和人类高质量生活条件的基础，经过变换处理后再供用户使用的电能占全国总发电量的百分比值的高低是衡量一个国家技术进步的主要标志之一。文章阐述了开关型电力电子变换和控制基本原理，介绍了实用的半导体电力开关器件、电力电子开关型电源及电力电子补偿控制器的应用，最后，总结了电力电子技术的发展历史和今年十年电力电子技术变革。

Discussion on Electricity Power Conversion and Control Technology

Development and utilization of electricity power is the foundation of economy development and high quality living condition in the modern society. Percentage of the electricity energy which is available for users after conversion among the national total electricity capacity is one of the symbol of advanced technology in that nation. The article describes the basic principle of the switching mode electric electronic conversion and control technology; presents applications of the semi-conductor switching device, electric electronic switching mode power supply and electric electronic compensation controller; and at last, concludes the developing history of the electric electronic technology and its possible reform in the next decade.
