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 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 ninety's, 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 trigger circuit analysis of the effect of triggering circuit on the output voltage by wave phase shift in the AC-AC converter, deepen understanding of sine wave synchronous phase-shift trigger circuit operation principle and the function of each component, master debugging method of sine wave synchronous phase-shift trigger circuit, and introduces the sinusoidal phase shift a full-featured trigger circuit and its application.
