Hey, I have 6V flooded lead acid battery and its 235 Ah.
I am designing a MPPT controller with a buck converter. I was told that, output voltage regulation is only in float or any stage after Bulk stage. In the Bulk stage, the output voltage is clamped to the battery voltage as long as Vin > Vout. So we are controlling the current in this case and only the current. Since the voltage is clamped to the battery voltage in bulk stage, why it is not clamped to the battery voltage in float stage or any stage after? Meaning why do we need a voltage regulation in float stage since the output will be clamped to the battery voltage?
let's say I have a 12V power supply and I directly connected to a 6V battery that is in bulk stage, does this power supply voltage will be clamped to 6V and current coming is determined by battery resistance? if yes, then why it is not clamped to it after bulk stage?
I really appreciate if someone can help me understand this
