Abstract
A power supply system includes at least a first power supply module and at least one redundant power supply module. The at least one power supply module supplies power to an output terminal. The at least one redundant power supply module operates in a first state and in a second state. In the first state the second power supply module supplies power to the output terminal. In the second state the second power supply module provides standby power and operates in a burst mode (for example, such as a discontinuous conduction mode).
Claims22
A system, comprising:
- two AC-to-DC (alternating current-to-direct current) power supply modules, wherein a first AC-to-DC power supply module is a master power supply and a second AC-to-DC power supply module is a standby power supply, wherein in one mode the second AC-to-DC power supply module is to deliver power to an output terminal, and in another mode the second AC-to-DC power supply module is to provide standby power and to operate in a burst mode.
A system, comprising:
- two power supply modules, wherein a first power supply module is a master power supply and a second power supply module is a standby power supply, wherein in one mode the second power supply module delivers power to an output terminal, and in another mode the second power supply module is to provide standby power and to operate in a burst mode;
- wherein a predetermined threshold range of a current level of the system enables maximum subsystem efficiency at any given load level.
An apparatus comprising:
- two AC-to-DC (alternating current-to-direct current) power supply modules, wherein a first AC-to-DC power supply module is a master power supply and a second AC-to-DC power supply module is a standby power supply, wherein in one mode the second AC-to-DC power supply module is to deliver power to an output terminal, and in another mode the second AC-to-DC power supply module is to provide standby power and to operate in a burst mode.
