Abstract

In this paper, the deadbeat control of single-phase photovoltaic(PV) grid connected converter is studied, and the mathematical model of the control model is derived. The application of a large number of power electronic equipment will be reduced, considering the direct power supply of the DC load by the distributed power supply. In this paper, distributed generation is used as photovoltaic power generation system. It adopts maximum power point tracking control(MPPT), and sends part of power directly to DC load. The surplus power is transported to the grid, which not only ensures the maximum efficiency of energy, but also reduces the cost. In addition, this paper gives the real time calculation formula of inductance, and realizes the more precise control of the system by calculating the inductance on line. Finally, the system has been simulated and verified with Simulink.
