单周期控制在矩阵式交流稳压电源中的应用研究

Research of One-cycle Control Used in Matrix Fast AC Stabilizer

将单周期控制方法引入交流稳压电源的控制 ,其快速的动态响应和抗输入扰动性 ,正是稳压电源所需要的。主电路采用了由IGBT构成的矩阵式电路或称交流斩波串联补偿电路。交流斩波电路可以四象限运行 ,能量双向流动 ,电源适用于感性和容性负载。

One cycle control is used in the AC stabilizer,by which the controller corrects the switching errors in one swit ching cycle.An AC PWM converter circuit is used to compensate the grid in series through a transformer.The converter can work in four quadrant to make the energy flow in two directions.So the power is suitable for either the leading or the lagging load.Experiment proves that the instrument is excellent in dynamic response.
