For engineers engaged in the research and development of MPPT controllers, it is undoubtedly a difficult problem to select the best partner among many field effect tubes. Improper selection will not only affect the efficiency of the controller, but may also drag down the entire project schedule. Faced with thousands of choices, how can we choose the best model? This article will give you a detailed answer. First of all, we need to understand the characteristics of MPPT controller. As the brain of the solar photovoltaic system, the MPPT controller can detect the power generation voltage of the solar panel in real time, track the voltage and current value, and make the system charge the battery with the maximum power output. It has a built-in maximum power tracking algorithm, and its charging efficiency is 15%-20% higher than that of traditional PWM controller. The combination of multiple tracking algorithms can accurately find the best operating point within 1 second, and the MPPT tracking efficiency can reach up to 99.9%.
