摘要
Abstract
The circuit topology architecture of the cascading multi⁃level inverter was adopted in the photovoltaic(PV)grid⁃connected system. The control strategy of the PV grid⁃connected system based on the architecture is studied in this paper. In or⁃der to realize effective grid⁃connecting and get the same phase between current and grid voltage,the hybrid control mode with staircase control and current loop control was applied on the basis of the control strategies of single⁃stage PV grid⁃connected sys⁃tem and the cascaded inverter. Matlab/Simulink simulation analysis of the PV grid⁃connected system was conducted to verify the feasibility of the control method. The application of current loop control using PR regulator improved the efficiency of the casca⁃ded inverter.关键词
