Abstract

The invention discloses an output control method for maximum power of a photovoltaic module. The output control method comprises the steps of 1, enabling the photovoltaic module to charge a supercapacitor; 2, continuously monitoring voltage and charging current at the two ends of the supercapacitor to obtain the output power of the photovoltaic module; and 3, outputting the energy stored by the supercapacitor to a load when it is detected that the output power is to be reduced. By virtue of the output control method for maximum power of the photovoltaic module, the problem of inconvenience in tracking of the maximum power point of the photovoltaic module in the prior art can be overcome, the tracking of the maximum power point of the photovoltaic module is realized, and maximum of the discharging efficiency is also realized.

Description

technical field [0001] The invention relates to the output control of the maximum power of a photovoltaic module, in particular to a method for controlling the output of the maximum power of a photovoltaic module. Background technique [0002] Under certain sunlight intensity and ambient temperature, the load impedance connected to the photovoltaic module is different, and the output power is different. It can be known from circuit theory that the output power of photovoltaic modules can reach the maximum value only when the connected load impedance is equal to the real-time best matching impedance of photovoltaic modules. Therefore, in the photovoltaic power generation system, to improve the overall efficiency of the system, an important way is to adjust the connected load impedance in real time so that it is always equal to the best matching impedance of the photovoltaic module. This process is called maximum power point tracking. . [0003] Nowadays, how to track the ma...
