POWER SUPPLYING SYSTEM AND POWER SUPPLY ADJUSTMENT METHOD

A power supplying system and a power supply adjustment method are provided. The power supplying system includes a plurality of power suppliers. Each power supplier is connected to a power source respectively, and the power suppliers are connected to a load and a bus together. Each power supplier includes a current equalizer and a voltage converter electrically connected with the current equalizer. Each current equalizer generates a voltage conversion signal according to at least an output power information and an output current of the corresponding power supplier. Each current equalizer generates a voltage adjustment signal according to the voltage conversion signal, other voltage conversion signals which are received by the bus from other current equalizers, and an output voltage provided to the load by the corresponding power supplier. Each voltage converter adjusts an input voltage of the corresponding power source according to the voltage adjustment signal.
