Description
The power sharing feature discussed above can be further modi ed to allow individual maximum power point tracking for both inputs. The ability to regulate the output voltage is sacri ced to allow for power control on each loop. As step-up converters for renewable systems generally feed into a fixed DC bus the loss of output regulation does not present a problem.
Dual MPPT control scheme
CURRENT SHARING MICROCONTROLLER CODE
Using current mode control the current through each boost inductor can be controlled to a set level. The CW multiplier is a charge pump, therefore the input and output current ( and with it charge) are related to another.
