Hey everyone,
I just finished designing a buck boost converter. The converter is implementing a Maximum Power Point Tracking (MPPT) algorithm at its input. Now I would like to charge a 12 Volts lead-acid battery with the buck-boost. The voltage at the output of the converter is held by the voltage of the
lead-acid battery. But in order to charge the battery properly, the current into the battery from the converter is to be controlled.
I could not figure out a way to control the output current of the converter. How can the current be controlled?
