摘要电网电压输出电压的恒定在输电过程中具有日益重要的作用，本篇论文采用了补偿型控制法，不仅结构较为简单，而且易于后期调节，在成本控制以及设备体积跟容量方面相比同类型其他产品有着极大的优势。49117

本论文采用的主电路拓扑结构是基于双PWM型变换器的补偿型单相稳压交流电源，其中最重要的部分为PWM的整流器以及逆变器，逻辑结构方面，则采用了补偿型方式，通过PWM整流器将电网电压转为直流，后经过逆变器转变为交流，最后通过补偿机构将根据电压与额定电压的比对补偿至额定值，最终达到稳压的目的。

本次仿真过程利用的是Matlab R2014a中的Simulink工具，利用Simulink中的Sim Power System以及Simulink库中的各个元器件以及相应模块，最终通过搭建电路所仿真出来的波形在预计的误差范围内，为接下来的学习与工作提供了良好的借鉴经验。

Title   Design of single phase AC regulated power supply  

Abstract

Therefore, keep the output end of the power grid voltage stability is still not important. In this paper, the final choice compensation type AC voltage stabilized source as the measures for the implementation of the project, compared with the other same type of power, the capacity of the various components of the circuit to a lot of small, has a great advantage in terms of cost control and the volume of the equipment and capacity.

In this paper, the main circuit topology is based on Dual PWM converter compensation type single-phase AC voltage stabilized power supply, which is the most important part of the PWM rectifier and inverter, logic structure, the use of a compensation way, through the PWM rectifier will power grid voltage is changed into a direct, through the inverter into a communication. Finally, the compensation mechanism will according to voltage and rated voltage ratio compensation to the rated value, and ultimately achieve the regulator.  

The simulation process using the Simulink tool in MATLAB R2014a, using Simulink SIM power system and Simulink Library of various components and the corresponding module. Finally simulation results and experimental results can meet the basic requirements of the experiments in front, for next study provides a good reference.
