摘要：The solar radiation conditions and environmental factors on the shadow of the power generation resulted in loss of efficiency. In this paper, a simple structure with interleaved isolation converter according to the characteristics of the hardware circuit is proposed in order to improve the conversion efficiency of photovoltaic grid system. First, the hot spot effect and discretization of solar panels according to the characteristics of the micro- inverter with a lot of promotion is analyzed. The least action recursive method is involved, which has high computing precision, and therefore is more suitable for distributed micro- inverter system. The PC56F8245 chip is chosen to overcome the loss of photovoltaic energy and improve the conversion efficiency. The stability and high accuracy has been proved through the related experiments.
