Abstract
A power supply equipment supplies power to a critical load and a non-critical load. The power supply equipment includes a plurality of power supplies coupled in parallel and a system controller. The system controller is coupled to the power supplies, and communicates with the power supplies to set a specific sequence. The system controller notifies the power supplies to adjust operating frequencies to be inconsistent according to the specific sequence.

A power supply equipment, configured to supply power to a critical load and a non-critical load, the power supply equipment comprising:
- a plurality of power supplies, coupled in parallel, and each power supply comprising:
- a control module, configured to control one power supply belonging to the control module to convert an input power according to an operating frequency so as to supply power to the critical load and the non-critical load, and
- a system controller, coupled to the control module of each power supply, and configured to communicate with the control module to set a specific sequence,
- wherein the system controller is configured to notify the control modules of the plurality of power supplies to adjust the operating frequencies to be inconsistent according to the specific sequence.
A method operating a power supply equipment, the power supply equipment configured to supply power to a critical load and a non-critical load, and the power supply equipment comprising a plurality of power supplies, the method comprising steps of:
- converting an input power, by the power supplies, to supply power to the critical load and the non-critical load according to operating frequencies,
- communicating with each other of the power supplies to set a specific sequence, and
- notifying the power supplies to adjust the operating frequencies to be inconsistent according to the specific sequence.
