摘　　要：为解决低压电网线路中由于电压调节技术原因导致电压畸变的问题,提出了一种新型低压电网线电压调节器LVR(line voltage regulator),并设计了磁控电感MCI(magnetically controlled inductor)元件。该元件可以使用一个较小的铁芯,省去了开关元件和其他运动部件,减小了铁损耗和材料损耗。基于MCI设计三相电路模型及实验平台,通过实验与仿真结果,对比电压的变化和效率均达到预期结果,验证了具有电压的无极调节功能和高鲁棒性,使得该器件可以用于低压电网电路的调节,为电压调节器的进一步研究提供参考。To solve the problem of voltage distortion caused by the voltage regulation technology in the line of low-voltage power grid,a novel low-voltage line voltage regulator(LVR)is proposed.In addition,a magnetically controlled in-ductor(MCI)component is designed,which can use a smaller core instead of switching components and other moving parts,thus reducing the iron loss and material loss.Based on the MCI,a three-phase circuit model and experimental platform were designed.According to the comparison between experimental and simulation results,both the voltage variation and efficiency reached the expected result.The function of voltage stepless regulation and a high robustness were verified,so that the device can be applied to the circuit regulation of low-voltage grid,providing reference for the further research on voltage regulators in the future.
