正弦波同步移相触发电路 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、、分析了在交—交变频器中采用正弦波移相触发电路对输出电压的影响,并介绍了一种功能齐全的正弦波移相触发电路及其应用。变频器正弦波触发电路输出电压移相控制电压 Sine wave synchronous trigger circuit Abstract Power electronic technology is based on a power electronic device for power transfer and control of science, is a comprehensive subject of a multi-disciplinary nineteen fifties was born in 70s 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 eightys and early ninetys, with the power of MOSFET and IGBT as the representative, set power conductor composite 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. One of the basic forms of power electronic circuit AC - AC - AC converter which is a form of AC can be changed into another form of alternating current circuit. AC voltage regulator with conventional AC voltage transformer compared to its volume and the weight should be much smaller. AC output AC voltage regulator is it not sine wave the harmonic component big power factor is low. Sine wave synchronous
