Abstract：The voltage-fed Z-source inverter will be applied to UPS system to make the inverter circuit can operate in shoot-through state and achieve the buck-boost function through controlling the shoot-through vector. The thesis introduces and analyzes the topology、operating principle、control method of Z-source inverter and establishes voltage and current double closed-loop control system to keep the output voltage constant, has a good dynamic performance and steady-state performance. Finally,Matlab/Simulink software is applied to the simulation of UPS system and the validity of the theoretical analysis is proved by simulation results.
