Description

technical field [0001] The invention relates to an electronic system, in particular to a solar photovoltaic control system with dynamically adjustable output of current and voltage. Background technique [0002] Solar energy is a clean and efficient renewable energy. The Maximum Power Point Tracking (MPPT for short) system is a system that adjusts the working conditions of solar cells so that the photovoltaic cells can always convert solar energy into electrical energy output to the greatest extent when the environmental conditions such as light intensity and temperature change. Technology. Using different software algorithms and control methods, the efficiency of MPPT varies greatly. Therefore, the market needs an MPPT module that can adapt to the actual outdoor photovoltaic power generation system requirements and environmental changes, so that it can be used in grid-connected or non-grid-connected photovoltaic systems. The MPPT module enables photovoltaic cells to maxi...
