A new type of single-phase ac converter is presented, it uses less power devices and realizes the single stage power conversion, and then the power density and transformation efficiency of the converter are improved. Through the analysis of the circuit topology structure and working principle of the new type of single-phase ac converter,using the volt-second characteristics of the inductor, the MATLAB/Simulink performs the simulation for the open loop ac converter circuit, and the experimental circuit implement the circuit topology. The experimental results and simulation results have consistency, and both of them verify the validity and reliability of the new type of single-phase ac converter.
