摘要
电力电子技术是研究采用电力电子器件实现对电能的换和控制的科学,是20世纪50年代诞生70年代迅速发展起来的一门多学科互相渗透的综合性技术学科。这些技术包括以节约能源、提高照明质量为目的的绿色照明技术。以节约能源、提高运行可靠性并更好地满足产要求为目的的交流变频调速技术以提高电力系统运行的稳定性、可控制性为目的,并可有效节能的灵括、柔性、交流输电技术等等。随着电力半导体制造技求、徽电子技术、汁算机技术以及控制理论的不断进步。电力电子技求向着大功率、高频化及智能化方向发展,应用的领域将更加广阔。八十年代末期和九十年代初期发展起来的、以功率MOSFET和IGBT为代表的、集高频、高压和大电流于一身的功率导体复合器件表明传统电力电子技术已经进入现代电力电子时代。
电力电子线路的基本形式之一即交流—交流—交流变换电路它是将一种形式的交流电能变换成另一种形式交流电能电路。交流调压器与常规的交流调压变压器相比它的体积和重量都要小得多。交流调压器的输出仍是交流电压它不是正弦波其谐波分量较大功率因数也较低。
正弦波同步移相触发电路分析研究了在交—交变频器中采用正弦波移相触发电路对输出电压的影响, 加深理解正弦波同步移相触发电路的工作原理及各元件的作用,掌握正弦波同步移相触发电路的调试方法,并介绍了一种功能齐全的正弦波移相触发电路及其应用。
正弦波同步移相触发电路由同步移相,脉冲放大等单元电路组成,对同步移相、脉冲放大、强触发等将做详细的讲解。

Abstract
Power electronic technology is based on a power electronic device for power transfer and control of science, is prehensive subject of a multi-disciplinary een fifties was born in 70's with the rapid development of mutual infiltration. These techniques include green lighting technology to save energy, improve the quality of lighting for the purpose of. To save energy, improve the running reliability and better meet the requirement of production for AC variable frequency speed control technology for the purpose to improve the stability of power system operation, the control for the purpose, and may be effective in saving spirit includes, flexible, AC transmission technology. With the development of power semiconductor manufacturing technology, Hui Electronic Technology, computer technology and the continuous progress of control theory. Power electronic technology towards high power, high frequency and intelligent direction, field of application will be more broad. Development of the late eighty's and early y's, with the power of MOSFET and IGBT as the representative, set power posite device of high frequency, high voltage and large current in a show that the traditional power electronic technology has entered the modern era of power electronics.
