Abstract
A multi-power management system and an operation method for the multi-power management system are provided. The multi-power management system includes multiple adapters and a power supply circuit. The adapters respectively provide multiple powers. The power supply circuit receives multiple input power values of the adapters, and calculates multiple input power value contribution ratios of the adapters according to the input power values. The power supply circuit further provides a control signal according to a sum of the output current values of multiple output current values of the powers and the input power value contribution ratios. The adapters adjust the output current values and multiple output voltage values respectively in response to the control signal.
