摘要
A power system with a combination of active current sharing and droop current sharing is disclosed. The power system includes a system load and plural power supplies connected with each other and connected to the system load. The power supplies are configured to respectively output a load current to the system load, and each power supply includes an active current sharing circuit and a droop current sharing circuit. The active current sharing circuit is configured to enter an operation or shutdown mode depending on whether the load current is higher than a first current set point. The droop current sharing circuit is configured to enter an operation or shutdown mode depending on whether the load current is higher than a second current set point. Hence, each power supply can respectively output an equal share of the load current by an active current sharing technique and/or a droop current sharing technique.
