In order to achieve photovoltaic high voltage to connect the grid, this paper proposed a novel grid-connected inverter:cascaded photovoltaic grid-connected inverter. Next, this paper also put forwards a very simple and effective control strategy for cascaded photovoltaic grid-connected inverter. Finally, MATLAB/SIMULINK10.0 has verified the performance of proposed control strategy, and this novel inverter has very high grid-connected power factor.%为了实现光伏高压并网发电，本文提出了一种新型的并网逆变器---级联型光伏并网逆变器。针对级联型光伏并网逆变器提出了一种简单有效的并网控制算法；最后MATLAB/SIMULINK10.0仿真结果表明了所提出的控制算法的有效性和正确性且该逆变器具有很高的并网功率因数。
