مبدل های dc dc برای سیستمهای تغذیه شده با فتوولتاییک به همراه باطری قابل شارژ

many mobile and off-grid devices include electronics and other electrical consumers like servo drives, which need a quite low supply power. since the price for photovoltaic modules drops continuously, photovoltaic power supply is interesting in more and more applications. in solar powered systems, a battery is needed to store energy for the night and cloudy periods. the power electronics of such a system needs to convert the voltage of the solar panel to the voltage of the battery. furthermore, it has to control the current in order to operate the solar panel in the maximum power point or it has to shut down battery charging in case that the maximum battery voltage is reached.
