Abstract :
By contrast with fossil fuel, which has many environmental problems such as exhausted gas or air pollution, the photovoltaic power generation system has a great future. The interface connecting photovoltaic and grid is a key element. This paper describes the topology of main circuit, control methods, design of passive filter. The important point of this paper is control methods for grid-connecting, PFC, control methods of power direction. Based on the analyzing of SPWM (sinusoidal pulse-width-modulated) technique control method in detail, this paper improves the control means. This paper proposes a neoteric grid-connecting inverter, which synchronizes a sinusoidal AC output current with a utility line voltage, and control the power generation of each photovoltaic battery cell.
