The circuit topology of a novel three-phase quasi-Z source AC-AC converter is proposed,and the basic working principle and structure of the circuit are analyzed.In addition,the relationship between input voltage and output voltage is also derived.This circuit topology is controlled by a pulse width modulation method,which can achieve the ef-fect of changing the output voltage.MATLAB/Simulink is used to build a simulation model,and the simulation results are analyzed.Finally,an experimental circuit was built on the basis of the simulation model,and experimental results verified the feasibility of the proposed circuit topology and the correctness of circuit analysis.
