摘　　要：针对我国部分地区的低压配电问题,以单相智能调压器为设计对象,设计基于BOOST升压电路的单相功率因数校正电路,使得输入侧在功率因数为1的状态下运行,给逆变侧输入稳定的直流电压,最后利用全桥逆变电路加入LC滤波器来产生用户需要的、质量可靠的系统电压。同时,基于MATLAB/SIMULINK仿真实验平台,搭建了该装置的系统仿真模型,完成系统的稳态和瞬态实验。仿真结果表明该装置在整个调压范围内都能完成输出稳定电压的任务。Aiming at the problem of low voltage distribution in some regions of our country,setting the single phase intelligent regulator as the design object, a single-phase power factor correction circuit based on BOOST circuit is deveopled, which enables the input side to run when power factor is 1, inputs stable DC voltage to the inverter side, and finally generates a voltage system with reliable quality that user needs by adding LC filter to the full bridge inverter circuit. At the same time, based on the MATLAB/SIMULINK simulation experiment platform, the system simulation model of the device is built, and the steady and transient experiments of the system are completed.The simulation results show that the device can accomplish the task of stabilizing output voltage of AC 220 V in the whole voltage regulation range, improving the power factor of the power grid,ensuring the reliability of the power supply, and increasing the qualified rate of the voltage.
