1、 摘要摘要 随着各行各业控制技术的发展和对操作性能要求的提高， 许多行业的用电设 备都不是直接用交流电网提供的交流电作为电能源， 而是通过各种形式对其进行 变换，从而得到各自所需的电能形式。逆变就是对电能进行变换和控制的一种基 本形式，它完成将直流电变换成交流电的功能。现代逆变技术是研究现代逆变电 路的理论和应用设计方法的学科，这门学科综合了现代电力电子开关器件技术、 现代功率变换技术、模拟和数字电子技术、PWM 技术、开关电源技术和现代控制 技术等多种实用设计技术， 已被广泛的用于工业和民用领域中的各种功率变换系 统和装置中。 本文重点从改变 IGBT 开关频率来得到我们想要的交流电源，同时
2、引入 PWM 技术 PWM 改变逆变电路输出电压的大小，以及输出频率。研究无源逆变控制技术 的绿色变频电源技术，对当今提出的“节能、高效、绿色、环保”工业口号的实 现具有重要意义。 ABSTRACT With the development of control technology in all walks of life and the improvement of operating performance requirements, many electrical equipment industry is not communicate directly with the grid
3、provided by alternating current (ac) as the electric energy, but through various forms of transformation, thus the electricity required to get their respective forms. Inverter is the power transformation and control of a basic form, it will complete the function of the direct current into alternatin
4、g current (ac). Modern inverter technology is the study of modern design method of inverter circuit theory and application of the subject, the subject combines modern technology, modern power transformation technology power electronic switching devices, analog and digital electronic technology, the
5、PWM, switching power supply technology and modern control technology and so on the many kinds of practical design, has been widely used in industrial and civil in the field of all kinds of power conversion system and device. This paper mainly from the change of IGBT switch frequency ac power to get
6、what we want, at the same time introduced the PWM PWM changing the size of the inverter circuit output voltage, and output frequency. Research of passive inverter control technology of inverter power source green technology, put forward by the of todays “energy saving, efficient, green and environmental protection industry the realization of the slogan is of great significance. 目录目录 总体设计思想总体设计思想 1 第第一一章章 整流电路整流电路 2 第第二二章章 逆变电路逆变电路
