Solar panel open voltage tracking type real-time MPPT control system and solar panel open voltage tracking type real-time MPPT control method using the same
Solar panel open voltage tracking type real-time MPPT control system and solar panel open voltage tracking type real-time MPPT control method using the same
The present invention relates to a solar panel open voltage tracking type real-time MPPT control system and a solar panel open voltage tracking type real-time MPPT control method using the same, and more particularly, tracking the maximum amount of power by periodically updating the open voltage of a solar panel A solar panel open voltage tracking real-time MPPT control system capable of improving the failure rate, and a solar panel open voltage tracking real-time MPPT control method using the same. The solar panel open circuit voltage tracking real-time MPPT control system and control method according to the present invention periodically and continuously measures the open voltage value, which is the voltage value in the no-load state of the solar panel, and updates the measured open circuit voltage value in real time and the maximum By updating the reference voltage for wattage tracking and periodically changing the switching frequency and frequency duty ratio settings for switching control, it is possible to efficiently track the maximum wattage of the solar panel that is sensitive to the surrounding environment, It can improve the maximum wattage tracking failure rate
