摘　　要：鉴于电力电子相关技术和智能电网技术的发展,配电用电力电子变压器技术得到了广泛的研究。提出了两类单相交流电源输入、三相交流低压输出、低压端增加阻抗变换器的电力电子变压器拓扑:第一类可以实现单向能量传输,由交流推挽变换器、阻抗变换器(PFC)和电压源逆变器构成;第二类可以实现双向能量传输,由交流推挽变换器、矩阵变换器、阻抗变换器(VSR)和电压源逆变器构成。在理论分析的基础上,利用MATLAB/Simulink进行了仿真分析,所得结果验证了所提方案的正确性。In view of the development of power electronics and smart grid technology,the power electronic transformer technology has been widely studied for power distribution.This paper proposes two kinds of power electronic transformer topologies with single-phase AC power input,three-phase AC low voltage output and impedance converter added at lowvoltage side：the first kind can implement unidirectional energy transmission,it is made up of AC push-pull converter,impedance converter（PFC）and voltage source inverter;and the second implement bidirectional energy transmission,consisting of AC push-pull converter,matrix converter,impedance converter（VSR）and voltage source inverter.On the basis of theoretical analysis,the simulation analysis is conducted with MATLAB/Simulink,and the results verify the correctness of the proposed scheme.
