摘要
针对太阳能电池工作原理的特殊性,提出了一种多电平光伏并网逆变器输出能量最大化的设计方法,在以单位功率因数输出高质量电流波形的同时,保证了太阳能电池电势能的不间断输出。同时给出一种有效的正弦脉宽调制(SPWM)方案,通过改变基本逆变单元的连接方式,实现六电平输出。仿真和实验结果验证了该设计的可行性和有效性。
The design of multilevel grid-connected photovoltaic inverter to maximizing output energy is introduced in accordance with the specialty of solar battery.While outputting the current of high quality at unit power factor,the device also ensures a continuous output of electrical potential energy.The paper also proposes an effective sinusoidal pulse width modulation （SPWM） control scheme, which get six-level signal by changing the connection mode of basic inverter cells.The simulation and experimental results verify the proposed design.
