摘要
光伏逆变器是光伏发电系统的核心部分,对光伏逆变器最大功率点跟踪(MPPT)至关重要,它的效率高低直接影响着整个并网系统的效率。从电气安全的角度考虑,逆变器需要采用三相四线制接线方式。文章针对这种三相四线制三电平光伏逆变器提出一种基于DSP2812的新型的控制方法。
PV inverter is the core part of the photovoltaic power generation system; and for photovoltaic inverter maximum power point tracking （MPPT） is essential, its efficiency will directly affect the efficiency of the whole grid system. Considering from the point of view of electrical safety, inverters require three-phase four-wire connection. In this paper, a new control method based on DSP 2812 is proposed for the three-phase four-wire system three-level photovoltaic inverter.
