Abstract: 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.
