摘　　要：采用一种无自耦变压器的方案,通过改变拓扑中的3组桥臂的状态,从而达到稳压的目的.设计了一种高效的测控系统,通过对输入输出电压实时检测,微控制器产生相应的PWM信号和控制信号,并且通过硬件逻辑电路对控制信号的处理,有效地减轻了微控制器的负担,增加了系统的安全性和稳定性,采用新型的三臂式拓扑结构,提高了稳压器的整体效率.In this paper, the project of none-autotransformer was introduced which can achieve voltage regulation by changing the three groups of bridge arm in the topology, in the meaning time a kind of measurement and control system with high-efficiency was designed. Through the real-time detection of the input voltage, the output voltage, the relevant PWM signal and control signal produced by micro control unit（MCU）, and then after disposing the control signal through hardware logic circuit, the burden of MCU is relieved efficiently also the safety and stability of the system was increased. Using new topology, it improved the efficiency of the whole system.
