| Abstract: | The circuit topology structure, mathematical model and control structure of a three-phase photovoltaic grid connected inverter are analyzed. The control structure adopts synchronous rotation cordinate system based on PI control, which consists of the double closed loop control of the outer voltage loop and inner current loop, achieving decoupling control of active power and reactive power. It can agilely achieve unit power factor connected grid. |
