Abstract In view of these problems, large volume, large input harmonic and Low power factor of Traditional AC/DC/AC single-phase AC regulated power supply. Designed a single-phase AC regulated power supply based on PWM Chopping conversion, The structure is compared to the traditional control saves the DC side capacitor. The LC filter parameters Selection considering multielement such as frequency characteristic, power factor, etc. From the minimum reactive capacity of filter to design the LC filter, which can not only Optimize the filter performance, but reduces the harmonic content in the line; In order to better inhibition the DC voltage disturbance and improve the stability of regulated power supply, The trinal-loop control method that the inductive current inner loop, the output instantaneous voltage central loop and effective value of output voltage outer loop were proposed to Improve the dynamic performance and the load adaptability of the power supply. Finally, using MATLAB simulated the system and lapped hardware platform, the simulation and experimental verified the feasibility of the topology and control method.
