摘　　要：采用AC/DC/AC三级式拓扑结构来实现对电能质量的调节,输入级可以对网侧的功率因数进行校正,使其近似等于1;中间DC/DC级将直流输入与直流输出进行电气隔离;输出级可以输出正弦化的交流电压。采用MATLAB/Simulink软件进行了仿真研究,证明可以实现对电能质量的调节。Electronic power transformer combines power electronic converter technology with high-frequency transformer, and can realize self-regulating , oil-free, and adjust the power quality. This paper uses AC/DC/AC 3 level topology structure to adjust the power quality,the input stage can adjust power factor in the grid side,make its value approximately equal to 1. The middle stage can insulate the DC input from the DC output. The output stage can output sinusoidal AC voltage. This paper uses MATLAB/Simulink software to carry on the simulation experiment, which proves that it can be used to adjust the power quality.
