双Buck交流电压调节器的建模与仿真

Modeling and simulation of dual Buck AC voltage regulator

斩控调压控制技术作为一种新型交流调压技术,解决了相控调压技术含有大量不易滤除谐波和功率因数较低等问题,是一种很有发展前景的调压技术。双Buck交流电压调节器的拓扑解决了传统AC/AC变换器开关器件死区电感过电压等问题,控制方式也比较简单。建立双Buck交流电压调节器数学模型和控制模型,并对其控制环路校正进行了设计。

As a new type of AC voltage regulating technology,the chopping control technology solves the problems that the phase control technology is not easy to filter a lot of harmonic and the power factor is low. It is a promising voltage regulating technology. The topology of dual Buck AC voltage regulator solves the over-voltage problem of dead zone inductance of switch device for traditional AC/AC converter,and the control method is simple. So the mathematical model and control model for dual Buck AC voltage regulator are established,and the control loop correction is also designed.
