CURRENT SHARING CONTROL CIRCUIT, POWER PROVIDER, AND POWER SUPPLY SYSTEM THEREOF

A current sharing control circuit includes a controller and a current feedback circuit. The controller is configured to output a current control signal to a power supply circuit for indicating an output terminal of the power supply circuit. The current feedback circuit is configured to output a corresponding feedback signal to a current sharing bus based on the current control signal. The current feedback signal is a current signal. The controller is also configured to receive a voltage of the current sharing bus and adjust the current control signal based on the voltage of the current sharing bus. Thus, the current sharing control circuit achieves a stable and precision current sharing control of the output currents of power providers in a power supply system, which are electrically connected in parallel. A power provider and a power supply system are also provided.
