Maximum power tracking among different groups of distributed power sources with uniform time/voltage distribution control

An apparatus, comprising:

• groups of distributed-input series-output (DISO) converters actively controlled by a common maximum power tracking (MPT) controller, a uniform time distribution (UTD) controller, and a group uniform voltage distribution (UVD) controller, wherein
• the MPT controller is configured to actively control a plurality of DISO converters in one enabled group of DISO converters to update a present group-peak power voltage of the DISO converters within the enabled group, while remaining groups of DISO converters are controlled to hold most recent grouped peak power voltages updated during a previous uniform time window of an active MPT control, and
• the UTD controller is configured to enable input voltages of the one enabled group to be actively controlled to track a new group peak power voltage of associated power sources connected to the DISO converters within the enabled group, while the remaining groups are disabled from being actively controlled for their respective new group peak power voltages, and are controlled to hold most recent group peak power voltages, the most recent group peak power voltages are previously updated during previous uniform time windows of the active MPT control using the common MPT controller,
• each UVD controller is dedicated per one group of DISO converters and is configured to actively equalize distributed input voltages of the DISO converters belonging to the associated converter group,
• equal input voltages for one group of DISO converters have a different voltage from that of the equal input voltages for another group of DISO converters, and
• the number of the group UVD controllers are equal to the number of groups of DISO converters.
