Abstract: A power supply system and method include multiple power conversion units (PCUs) with independent power generation control and a PCU-to-PCU regulation of power, handoff control system to transfer control of power regulation to a load among the PCUs. The multiple PCUs maintain independent power generation control to collectively provide power to the load and handoff regulation of the power to the load from one PCU to another PCU. The term “handoff” refers to communication between PCUs that affects a transfer and acceptance of regulation of power control. The independent PCU power generation control with singularly located but transferable control of the regulation of power provides a flexible dynamic power supply.
