摘要
分析、设计了一种结构简单、集充电和逆变功能于一体的大功率光伏逆变系统。本系统以Intel 80C196MC 芯片为控制核心,采用自寻最优控制方式实现太阳电池的最大功率点跟踪(MPPT)。同时逆变器使用 SPWM 控制方式和新型 PI 调节器将直流电迅速逆变为220V/50Hz 的标准正弦波单相交流电源。
This paper analyzes and designs a kind of high power photovoltaic inverter system containing charge and inversion function with simple structure.The system,based on the chip of Intel 80C196MC,realizes the solar cell's maxi- mum power point tracking(MPPT) by looking for the best controlling method by itself.At the same time,inverter with SPWM controlling method and new type PI conditioner converts the DC into standard single phase alternating current of 220V and 50Hz rapidly.
